Extensions
Kotlin, similar to C# and Gosu, provides the ability to extend a class with new functionality without having to inherit from the class or use any type of design pattern such as Decorator. This is done via special declarations called extensions. Kotlin supports extension functions and extension properties.
Extension Functions
To declare an extension function, we need to prefix its name with a receiver type, i.e. the type being extended.
The following adds a swap
function to MutableList<Int>
:
fun MutableList<Int>.swap(index1: Int, index2: Int) {
val tmp = this[index1] // 'this' corresponds to the list
this[index1] = this[index2]
this[index2] = tmp
}
The this keyword inside an extension function corresponds to the receiver object (the one that is passed before the dot).
Now, we can call such a function on any MutableList<Int>
:
val l = mutableListOf(1, 2, 3)
l.swap(0, 2) // 'this' inside 'swap()' will hold the value of 'l'
Of course, this function makes sense for any MutableList<T>
, and we can make it generic:
fun <T> MutableList<T>.swap(index1: Int, index2: Int) {
val tmp = this[index1] // 'this' corresponds to the list
this[index1] = this[index2]
this[index2] = tmp
}
We declare the generic type parameter before the function name for it to be available in the receiver type expression. See Generic functions.
Extensions are resolved statically
Extensions do not actually modify classes they extend. By defining an extension, you do not insert new members into a class, but merely make new functions callable with the dot-notation on variables of this type.
We would like to emphasize that extension functions are dispatched statically, i.e. they are not virtual by receiver type. This means that the extension function being called is determined by the type of the expression on which the function is invoked, not by the type of the result of evaluating that expression at runtime. For example:
open class C
class D: C()
fun C.foo() = "c"
fun D.foo() = "d"
fun printFoo(c: C) {
println(c.foo())
}
printFoo(D())
This example will print "c", because the extension function being called depends only on the declared type of the
parameter c
, which is the C
class.
If a class has a member function, and an extension function is defined which has the same receiver type, the same name and is applicable to given arguments, the member always wins. For example:
class C {
fun foo() { println("member") }
}
fun C.foo() { println("extension") }
If we call c.foo()
of any c
of type C
, it will print "member", not "extension".
However, it's perfectly OK for extension functions to overload member functions which have the same name but a different signature:
class C {
fun foo() { println("member") }
}
fun C.foo(i: Int) { println("extension") }
The call to C().foo(1)
will print "extension".
Nullable Receiver
Note that extensions can be defined with a nullable receiver type. Such extensions can be called on an object variable
even if its value is null, and can check for this == null
inside the body. This is what allows you
to call toString() in Kotlin without checking for null: the check happens inside the extension function.
fun Any?.toString(): String {
if (this == null) return "null"
// after the null check, 'this' is autocast to a non-null type, so the toString() below
// resolves to the member function of the Any class
return toString()
}
Extension Properties
Similarly to functions, Kotlin supports extension properties:
val <T> List<T>.lastIndex: Int
get() = size - 1
Note that, since extensions do not actually insert members into classes, there's no efficient way for an extension property to have a backing field. This is why initializers are not allowed for extension properties. Their behavior can only be defined by explicitly providing getters/setters.
Example:
val Foo.bar = 1 // error: initializers are not allowed for extension properties
Companion Object Extensions
If a class has a companion object defined, you can also define extension functions and properties for the companion object:
class MyClass {
companion object { } // will be called "Companion"
}
fun MyClass.Companion.foo() { ... }
Just like regular members of the companion object, they can be called using only the class name as the qualifier:
MyClass.foo()
Scope of Extensions
Most of the time we define extensions on the top level, i.e. directly under packages:
package foo.bar
fun Baz.goo() { ... }
To use such an extension outside its declaring package, we need to import it at the call site:
package com.example.usage
import foo.bar.goo // importing all extensions by name "goo"
// or
import foo.bar.* // importing everything from "foo.bar"
fun usage(baz: Baz) {
baz.goo()
}
See Imports for more information.
Declaring Extensions as Members
Inside a class, you can declare extensions for another class. Inside such an extension, there are multiple implicit receivers - objects members of which can be accessed without a qualifier. The instance of the class in which the extension is declared is called dispatch receiver, and the instance of the receiver type of the extension method is called extension receiver.
class D {
fun bar() { ... }
}
class C {
fun baz() { ... }
fun D.foo() {
bar() // calls D.bar
baz() // calls C.baz
}
fun caller(d: D) {
d.foo() // call the extension function
}
}
In case of a name conflict between the members of the dispatch receiver and the extension receiver, the extension receiver takes
precedence. To refer to the member of the dispatch receiver you can use the qualified this
syntax.
class C {
fun D.foo() {
toString() // calls D.toString()
this@C.toString() // calls C.toString()
}
}
Extensions declared as members can be declared as open
and overridden in subclasses. This means that the dispatch of such
functions is virtual with regard to the dispatch receiver type, but static with regard to the extension receiver type.
open class D { }
class D1 : D() { }
open class C {
open fun D.foo() {
println("D.foo in C")
}
open fun D1.foo() {
println("D1.foo in C")
}
fun caller(d: D) {
d.foo() // call the extension function
}
}
class C1 : C() {
override fun D.foo() {
println("D.foo in C1")
}
override fun D1.foo() {
println("D1.foo in C1")
}
}
fun main(args: Array<String>) {
C().caller(D()) // prints "D.foo in C"
C1().caller(D()) // prints "D.foo in C1" - dispatch receiver is resolved virtually
C().caller(D1()) // prints "D.foo in C" - extension receiver is resolved statically
}
Note on visibility
Extensions utilize the same visibility of other entities as regular functions declared in the same scope would. For example:
- An extension declared on top level of a file has access to the other
private
top-level declarations in the same file; - If an extension is declared outside its receiver type, such an extension cannot access the receiver's
private
members.
Motivation
In Java, we are used to classes named "*Utils": FileUtils
, StringUtils
and so on. The famous java.util.Collections
belongs to the same breed.
And the unpleasant part about these Utils-classes is that the code that uses them looks like this:
// Java
Collections.swap(list, Collections.binarySearch(list,
Collections.max(otherList)),
Collections.max(list));
Those class names are always getting in the way. We can use static imports and get this:
// Java
swap(list, binarySearch(list, max(otherList)), max(list));
This is a little better, but we have no or little help from the powerful code completion of the IDE. It would be so much better if we could say:
// Java
list.swap(list.binarySearch(otherList.max()), list.max());
But we don't want to implement all the possible methods inside the class List
, right? This is where extensions help us.

@Documented @Retention(value=RUNTIME) @Target(value=TYPE) public @interface MXBean
Annotation to mark an interface explicitly as being an MXBean
interface, or as not being an MXBean interface. By default, an
interface is an MXBean interface if its name ends with MXBean
, as in SomethingMXBean
. The following interfaces
are MXBean interfaces:
public interface WhatsitMXBean {} @MXBean public interface Whatsit1Interface {} @MXBean(true) public interface Whatsit2Interface {}
The following interfaces are not MXBean interfaces:
public interface Whatsit3Interface{} @MXBean(false) public interface MisleadingMXBean {}
The MXBean concept provides a simple way to code an MBean
that only references a predefined set of types, the ones defined
by javax.management.openmbean
. In this way, you can be
sure that your MBean will be usable by any client, including
remote clients, without any requirement that the client have
access to model-specific classes representing the types
of your MBeans.
The concepts are easier to understand by comparison with the Standard MBean concept. Here is how a managed object might be represented as a Standard MBean, and as an MXBean:
| Standard MBean | MXBean |
|---|---|
public interface MemoryPoolMBean { String getName(); MemoryUsage getUsage(); // ... } |
public interface MemoryPoolMXBean { String getName(); MemoryUsage getUsage(); // ... } |
As you can see, the definitions are very similar. The only
difference is that the convention for naming the interface is to use
SomethingMXBean
for MXBeans, rather than
SomethingMBean
for Standard MBeans.
In this managed object, there is an attribute called
Usage
of type MemoryUsage
. The point of an
attribute like this is that it gives a coherent snapshot of a set
of data items. For example, it might include the current amount
of used memory in the memory pool, and the current maximum of the
memory pool. If these were separate items, obtained with separate
getAttribute
calls, then we could
get values seen at different times that were not consistent. We
might get a used
value that was greater than the
max
value.
So, we might define MemoryUsage
like this:
| Standard MBean | MXBean |
|---|---|
public class MemoryUsage implements Serializable { // standard JavaBean conventions with getters public MemoryUsage(long init, long used, long committed, long max) {...} long getInit() {...} long getUsed() {...} long getCommitted() {...} long getMax() {...} } |
public class MemoryUsage { // standard JavaBean conventions with getters @ConstructorProperties({"init", "used", "committed", "max"}) public MemoryUsage(long init, long used, long committed, long max) {...} long getInit() {...} long getUsed() {...} long getCommitted() {...} long getMax() {...} } |
The definitions are the same in the two cases, except
that with the MXBean, MemoryUsage
no longer needs to
be marked Serializable
(though it can be). On
the other hand, we have added a @ConstructorProperties
annotation
to link the constructor parameters to the corresponding getters.
We will see more about this below.
MemoryUsage
is a model-specific class.
With Standard MBeans, a client of the MBean Server cannot access the
Usage
attribute if it does not know the class
MemoryUsage
. Suppose the client is a generic console
based on JMX technology. Then the console would have to be
configured with the model-specific classes of every application it
might connect to. The problem is even worse for clients that are
not written in the Java language. Then there may not be any way
to tell the client what a MemoryUsage
looks like.
This is where MXBeans differ from Standard MBeans. Although we
define the management interface in almost exactly the same way,
the MXBean framework converts model-specific classes into
standard classes from the Java platform. Using arrays and the
CompositeData
and
TabularData
classes
from the standard javax.management.openmbean
package, it
is possible to build data structures of arbitrary complexity
using only standard classes.
This becomes clearer if we compare what the clients of the two models might look like:
| Standard MBean | MXBean |
|---|---|
String name = (String)
mbeanServer. |
String name = (String) mbeanServer. |
For attributes with simple types like String
, the
code is the same. But for attributes with complex types, the
Standard MBean code requires the client to know the model-specific
class MemoryUsage
, while the MXBean code requires no
non-standard classes.
The client code shown here is slightly more complicated for the
MXBean client. But, if the client does in fact know the model,
here the interface MemoryPoolMXBean
and the
class MemoryUsage
, then it can construct a
proxy. This is the recommended way to interact with
managed objects when you know the model beforehand, regardless
of whether you are using Standard MBeans or MXBeans:
| Standard MBean | MXBean |
|---|---|
MemoryPoolMBean proxy =
JMX. |
MemoryPoolMXBean proxy =
JMX. |
Implementing the MemoryPool object works similarly for both Standard MBeans and MXBeans.
| Standard MBean | MXBean |
|---|---|
public class MemoryPool implements MemoryPoolMBean { public String getName() {...} public MemoryUsage getUsage() {...} // ... } |
public class MemoryPool implements MemoryPoolMXBean { public String getName() {...} public MemoryUsage getUsage() {...} // ... } |
Registering the MBean in the MBean Server works in the same way in both cases:
| Standard MBean | MXBean |
|---|---|
{
MemoryPoolMBean pool = new MemoryPool();
mbeanServer. |
{
MemoryPoolMXBean pool = new MemoryPool();
mbeanServer. |
An MXBean is a kind of MBean. An MXBean object can be
registered directly in the MBean Server, or it can be used as an
argument to StandardMBean
and the resultant MBean
registered in the MBean Server.
When an object is registered in the MBean Server using the
registerMBean
or createMBean
methods of the
MBeanServer
interface, the object's class is examined
to determine what type of MBean it is:
DynamicMBean
then the MBean is a Dynamic MBean. Note that the class
StandardMBean
implements this interface, so this
case applies to a Standard MBean or MXBean created using
the class StandardMBean
.SMXBean
where
S
is any non-empty string, and
do not have an annotation @MXBean(false)
; and/or@MXBean(true)
or just @MXBean
.MemoryPoolMXBean
.
NotCompliantMBeanException
.
Every Java type that appears as the parameter or return type of a method in an MXBean interface must be convertible using the rules below. Additionally, parameters must be reconstructible as defined below.
An attempt to construct an MXBean that does not conform to the above rules will produce an exception.
The same naming conventions are applied to the methods in an MXBean as in a Standard MBean:
T getN()
, where
T
is a Java type (not void
)
and N
is a non-empty string, specifies
that there is a readable attribute called
N
. The Java type and Open type of the
attribute are determined by the mapping rules below.
The method final Class getClass()
inherited from Object
is ignored when looking for getters.boolean isN()
specifies that
there is a readable attribute called N
with Java type boolean
and Open type
SimpleType.Boolean
.void setN(T x)
specifies that there is a writeable attribute called
N
. The Java type and Open type of the
attribute are determined by the mapping rules below. (Of
course, the name x
of the parameter is
irrelevant.)The rules for getN
and
isN
collectively define the notion of a
getter. The rule for setN
defines
the notion of a setter.
It is an error for there to be two getters with the same name, or
two setters with the same name. If there is a getter and a setter
for the same name, then the type T
in both
must be the same. In this case the attribute is read/write. If
there is only a getter or only a setter, the attribute is
read-only or write-only respectively.
An MXBean is a kind of Open MBean, as defined by the javax.management.openmbean
package. This means that the types of
attributes, operation parameters, and operation return values must
all be describable using Open Types, that is the four
standard subclasses of OpenType
.
MXBeans achieve this by mapping Java types into Open Types.
For every Java type J, the MXBean mapping is described by the following information:
OpenType
.For example, for the Java type List<String>
:
List<String>
), is ArrayType
(1,
SimpleType.STRING
)
, representing a 1-dimensional
array of String
s.List<String>
), is String[]
.List<String>
can be converted to a String[]
using List.toArray(new
String[0])
.String[]
can be converted to a List<String>
using Arrays.asList
.If no mapping rules exist to derive opentype(J) from J, then J cannot be the type of a method parameter or return value in an MXBean interface.
If there is a way to convert
opendata(J) back to J then we say that J is
reconstructible. All method parameters in an MXBean
interface must be reconstructible, because when the MXBean
framework is invoking a method it will need to convert those
parameters from opendata(J) to J. In a proxy
generated by JMX.newMXBeanProxy
, it is the return values
of the methods in the MXBean interface that must be
reconstructible.
Null values are allowed for all Java types and Open Types, except primitive Java types where they are not possible. When converting from type J to type opendata(J) or from type opendata(J) to type J, a null value is mapped to a null value.
The following table summarizes the type mapping rules.
| Java type J | opentype(J) | opendata(J) |
|---|---|---|
int , boolean , etc(the 8 primitive Java types) |
SimpleType.INTEGER ,SimpleType.BOOLEAN , etc |
Integer , Boolean , etc(the corresponding boxed types) |
Integer , ObjectName , etc(the types covered by SimpleType ) |
the corresponding SimpleType |
J, the same type |
int[] etc(a one-dimensional array with primitive element type) |
ArrayType.getPrimitiveArrayType(int[].class) etc |
J, the same type |
E[] (an array with non-primitive element type E; this includes int[][] , where E is int[] ) |
ArrayType.getArrayType( opentype(E)) |
opendata(E)[] |
List< E> Set< E> SortedSet< E> (see below) |
same as for E[] |
same as for E[] |
| An enumeration E (declared in Java as enum E
{...} ) |
SimpleType.STRING |
String |
Map< K,V> SortedMap< K,V> |
TabularType (see below) |
TabularData (see below) |
| An MXBean interface | SimpleType.OBJECTNAME (see below) |
ObjectName (see below) |
| Any other type | CompositeType ,
if possible(see below) |
CompositeData |
The following sections give further details of these rules.
The 8 primitive Java types
(boolean
, byte
, short
, int
, long
, float
, double
, char
) are mapped to the
corresponding boxed types from java.lang
, namely Boolean
, Byte
, etc. The Open Type is the corresponding
SimpleType
. Thus, opentype(long
) is SimpleType.LONG
, and
opendata(long
) is java.lang.Long
.
An array of primitive type such as long[]
can be represented
directly as an Open Type. Thus, openType(long[]
) is ArrayType.getPrimitiveArrayType(long[].class)
, and
opendata(long[]
) is long[]
.
In practice, the difference between a plain int
and Integer
, etc, does not show up because operations in the JMX API
are always on Java objects, not primitives. However, the
difference does show up with arrays.
List<
E>
etc)A List<
E>
or Set<
E>
, such as List<String>
or Set<ObjectName>
, is mapped in the same way as an array of the
same element type, such as String[]
or ObjectName[]
.
A SortedSet<
E>
is also mapped in the
same way as an E[]
, but it is only convertible if
E is a class or interface that implements Comparable
. Thus, a SortedSet<String>
or
SortedSet<Integer>
is convertible, but a SortedSet<int[]>
or SortedSet<List<String>>
is not. The
conversion of a SortedSet
instance will fail with an
IllegalArgumentException
if it has a
non-null comparator()
.
A List<
E>
is reconstructed as a
java.util.ArrayList<
E>
;
a Set<
E>
as a
java.util.HashSet<
E>
;
a SortedSet<
E>
as a
java.util.TreeSet<
E>
.
Map<
K,V>
etc)A Map<
K,V>
or SortedMap<
K,V>
, for example Map<String,ObjectName>
, has Open Type TabularType
and is mapped
to a TabularData
.
The TabularType
has two items called key
and
value
. The Open Type of key
is
opentype(K), and the Open Type of value
is
opentype(V). The index of the TabularType
is the
single item key
.
For example, the TabularType
for a Map<String,ObjectName>
might be constructed with code like
this:
String typeName = "java.util.Map<java.lang.String, javax.management.ObjectName>"; String[] keyValue = new String[] {"key", "value"}; OpenType[] openTypes = new OpenType[] {SimpleType.STRING, SimpleType.OBJECTNAME}; CompositeType rowType = new CompositeType(typeName, typeName, keyValue, keyValue, openTypes); TabularType tabularType = new TabularType(typeName, typeName, rowType, new String[] {"key"});
The typeName
here is determined by the
type name rules detailed below.
A SortedMap<
K,V>
is mapped in the
same way, but it is only convertible if
K is a class or interface that implements Comparable
. Thus, a SortedMap<String,int[]>
is convertible, but a
SortedMap<int[],String>
is not. The conversion of a
SortedMap
instance will fail with an IllegalArgumentException
if it has a non-null comparator()
.
A Map<
K,V>
is reconstructed as
a java.util.HashMap<
K,V>
;
a SortedMap<
K,V>
as
a java.util.TreeMap<
K,V>
.
TabularData
is an interface. The concrete class that is
used to represent a Map<
K,V>
as
Open Data is TabularDataSupport
,
or another class implementing TabularData
that serializes as TabularDataSupport
.
An MXBean interface, or a type referenced within an MXBean
interface, can reference another MXBean interface, J.
Then opentype(J) is SimpleType.OBJECTNAME
and
opendata(J) is ObjectName
.
For example, suppose you have two MXBean interfaces like this:
public interface ProductMXBean { public ModuleMXBean[] getModules(); } public interface ModuleMXBean { public ProductMXBean getProduct(); }
The object implementing the ModuleMXBean
interface
returns from its getProduct
method an object
implementing the ProductMXBean
interface. The
ModuleMXBean
object and the returned ProductMXBean
objects must both be registered as MXBeans in the
same MBean Server.
The method ModuleMXBean.getProduct()
defines an
attribute called Product
. The Open Type for this
attribute is SimpleType.OBJECTNAME
, and the corresponding
ObjectName
value will be the name under which the
referenced ProductMXBean
is registered in the MBean
Server.
If you make an MXBean proxy for a ModuleMXBean
and
call its getProduct()
method, the proxy will map the
ObjectName
back into a ProductMXBean
by making
another MXBean proxy. More formally, when a proxy made with
JMX.newMXBeanProxy(mbeanServerConnection, objectNameX,
interfaceX)
needs to map objectNameY
back into interfaceY
, another MXBean interface, it does so with JMX.newMXBeanProxy(mbeanServerConnection, objectNameY,
interfaceY)
. The implementation may return a proxy that was
previously created by a call to JMX.newMXBeanProxy
with the same parameters, or it may create a new proxy.
The reverse mapping is illustrated by the following change to the
ModuleMXBean
interface:
public interface ModuleMXBean { public ProductMXBean getProduct(); public void setProduct(ProductMXBean c); }
The presence of the setProduct
method now means that the
Product
attribute is read/write. As before, the value
of this attribute is an ObjectName
. When the attribute is
set, the ObjectName
must be converted into the
ProductMXBean
object that the setProduct
method
expects. This object will be an MXBean proxy for the given
ObjectName
in the same MBean Server.
If you make an MXBean proxy for a ModuleMXBean
and
call its setProduct
method, the proxy will map its
ProductMXBean
argument back into an ObjectName
.
This will only work if the argument is in fact another proxy,
for a ProductMXBean
in the same MBeanServerConnection
. The proxy can have been returned from
another proxy (like ModuleMXBean.getProduct()
which
returns a proxy for a ProductMXBean
); or it can have
been created by JMX.newMXBeanProxy
; or it can have been created using Proxy
with an invocation handler that
is MBeanServerInvocationHandler
or a subclass.
If the same MXBean were registered under two different
ObjectName
s, a reference to that MXBean from another
MXBean would be ambiguous. Therefore, if an MXBean object is
already registered in an MBean Server and an attempt is made to
register it in the same MBean Server under another name, the
result is an InstanceAlreadyExistsException
. Registering
the same MBean object under more than one name is discouraged in
general, notably because it does not work well for MBeans that are
NotificationBroadcaster
s.
Given a Java class or interface J that does not match the other
rules in the table above, the MXBean framework will attempt to map
it to a CompositeType
as follows. The type name of this
CompositeType
is determined by the
type name rules below.
The class is examined for getters using the conventions above. (Getters must be public instance methods.) If there are no getters, or if any getter has a type that is not convertible, then J is not convertible.
If there is at least one getter and every getter has a
convertible type, then opentype(J) is a CompositeType
with one item for every getter. If the getter is
T getName()
then the item in the CompositeType
is called name
and has type opentype(T). For example, if the item is
String getOwner()
then the item is called owner
and has Open Type SimpleType.STRING
. If the getter is
boolean isName()
then the item in the CompositeType
is called name
and has type SimpleType.BOOLEAN
.
Notice that the first character (or code point) is converted to
lower case. This follows the Java Beans convention, which for
historical reasons is different from the Standard MBean
convention. In a Standard MBean or MXBean interface, a method
getOwner
defines an attribute called Owner
, while
in a Java Bean or mapped CompositeType
, a method getOwner
defines a property or item called owner
.
If two methods produce the same item name (for example, getOwner
and isOwner
, or getOwner
and getowner
) then the type is not convertible.
When the Open Type is CompositeType
, the corresponding
mapped Java type (opendata(J)) is CompositeData
. The mapping from an instance of J to a
CompositeData
corresponding to the CompositeType
just described is done as follows. First, if J
implements the interface CompositeDataView
, then that
interface's toCompositeData
method is called to do the conversion.
Otherwise, the CompositeData
is constructed by calling
the getter for each item and converting it to the corresponding
Open Data type. Thus, a getter such as
List<String> getNames()
will have been mapped to an item with name "names
" and
Open Type ArrayType(1, SimpleType.STRING)
. The conversion
to CompositeData
will call getNames()
and convert
the resultant List<String>
into a String[]
for the
item "names
".
CompositeData
is an interface. The concrete class that is
used to represent a type as Open Data is CompositeDataSupport
, or another class implementing CompositeData
that serializes as CompositeDataSupport
.
CompositeData
If opendata(J) is CompositeData
for a Java type
J, then either an instance of J can be
reconstructed from a CompositeData
, or J is not
reconstructible. If any item in the CompositeData
is not
reconstructible, then J is not reconstructible either.
For any given J, the following rules are consulted to
determine how to reconstruct instances of J from
CompositeData
. The first applicable rule in the list is
the one that will be used.
If J has a method
public static
J from(CompositeData cd)
then that method is called to reconstruct an instance of
J.
Otherwise, if J has at least one public
constructor with a ConstructorProperties
annotation, then one
of those constructors (not necessarily always the same one)
will be called to reconstruct an instance of J.
Every such annotation must list as many strings as the
constructor has parameters; each string must name a property
corresponding to a getter of J; and the type of this
getter must be the same as the corresponding constructor
parameter. It is not an error for there to be getters that
are not mentioned in the ConstructorProperties
annotation
(these may correspond to information that is not needed to
reconstruct the object).
An instance of J is reconstructed by calling a
constructor with the appropriate reconstructed items from the
CompositeData
. The constructor to be called will be
determined at runtime based on the items actually present in
the CompositeData
, given that this CompositeData
might come from an earlier version of
J where not all the items were present. A
constructor is applicable if all the properties named
in its ConstructorProperties
annotation are present as items
in the CompositeData
. If no constructor is
applicable, then the attempt to reconstruct J fails.
For any possible combination of properties, it must be the case that either (a) there are no applicable constructors, or (b) there is exactly one applicable constructor, or (c) one of the applicable constructors names a proper superset of the properties named by each other applicable constructor. (In other words, there should never be ambiguity over which constructor to choose.) If this condition is not true, then J is not reconstructible.
Otherwise, if J has a public no-arg constructor, and
for every getter in J with type
T and name N there is a corresponding setter
with the same name and type, then an instance of J is
constructed with the no-arg constructor and the setters are
called with the reconstructed items from the CompositeData
to restore the values. For example, if there is a method
public List<String> getNames()
then there must also be a method
public void setNames(List<String> names)
for this rule to apply.
If the CompositeData
came from an earlier version of
J, some items might not be present. In this case,
the corresponding setters will not be called.
Otherwise, if J is an interface that has no methods
other than getters, an instance of J is constructed
using a Proxy
with a CompositeDataInvocationHandler
backed by the CompositeData
being converted.
Otherwise, J is not reconstructible.
Here are examples showing different ways to code a type NamedNumber
that consists of an int
and a String
. In each case, the CompositeType
looks like this:
CompositeType
( "NamedNumber", // typeName "NamedNumber", // description new String[] {"number", "name"}, // itemNames new String[] {"number", "name"}, // itemDescriptions new OpenType[] {SimpleType.INTEGER, SimpleType.STRING} // itemTypes );
from
method:
public class NamedNumber { public int getNumber() {return number;} public String getName() {return name;} private NamedNumber(int number, String name) { this.number = number; this.name = name; } public static NamedNumber from(CompositeData cd) { return new NamedNumber((Integer) cd.get("number"), (String) cd.get("name")); } private final int number; private final String name; }
@ConstructorProperties
annotation:
public class NamedNumber { public int getNumber() {return number;} public String getName() {return name;} @ConstructorProperties({"number", "name"}) public NamedNumber(int number, String name) { this.number = number; this.name = name; } private final int number; private final String name; }
public class NamedNumber { public int getNumber() {return number;} public void setNumber(int number) {this.number = number;} public String getName() {return name;} public void setName(String name) {this.name = name;} public NamedNumber() {} private int number; private String name; }
public interface NamedNumber { public int getNumber(); public String getName(); }
It is usually better for classes that simply represent a
collection of data to be immutable. An instance of an
immutable class cannot be changed after it has been constructed.
Notice that CompositeData
itself is immutable.
Immutability has many advantages, notably with regard to
thread-safety and security. So the approach using setters should
generally be avoided if possible.
Recursive (self-referential) types cannot be used in MXBean
interfaces. This is a consequence of the immutability of CompositeType
. For example, the following type could not be the
type of an attribute, because it refers to itself:
public interface Node { public String getName(); public int getPriority(); public Node getNext(); }
It is always possible to rewrite recursive types like this so they are no longer recursive. Doing so may require introducing new types. For example:
public interface NodeList { public List<Node> getNodes(); } public interface Node { public String getName(); public int getPriority(); }
An MXBean is a type of Open MBean. However, for compatibility
reasons, its MBeanInfo
is not an OpenMBeanInfo
.
In particular, when the type of an attribute, parameter, or
operation return value is a primitive type such as int
,
or is void
(for a return type), then the attribute,
parameter, or operation will be represented respectively by an
MBeanAttributeInfo
, MBeanParameterInfo
, or
MBeanOperationInfo
whose getType()
or getReturnType()
returns the primitive name ("int
" etc).
This is so even though the mapping rules above specify that the
opendata mapping is the wrapped type (Integer
etc).
The array of public constructors returned by MBeanInfo.getConstructors()
for an MXBean that is directly
registered in the MBean Server will contain all of the public
constructors of that MXBean. If the class of the MXBean is not
public then its constructors are not considered public either.
The list returned for an MXBean that is constructed using the
StandardMBean
class is derived in the same way as for
Standard MBeans. Regardless of how the MXBean was constructed,
its constructor parameters are not subject to MXBean mapping
rules and do not have a corresponding OpenType
.
The array of notification types returned by MBeanInfo.getNotifications()
for an MXBean that is directly
registered in the MBean Server will be empty if the MXBean does
not implement the NotificationBroadcaster
interface.
Otherwise, it will be the result of calling NotificationBroadcaster.getNotificationInfo()
at the time the MXBean
was registered. Even if the result of this method changes
subsequently, the result of MBeanInfo.getNotifications()
will not. The list returned for an MXBean that is constructed
using the StandardMBean
or StandardEmitterMBean
class is derived in the same way as for Standard MBeans.
The Descriptor
for all of the
MBeanAttributeInfo
, MBeanParameterInfo
, and
MBeanOperationInfo
objects contained in the MBeanInfo
will have a field openType
whose value is the OpenType
specified by the mapping rules above. So even when getType()
is "int
", getDescriptor().getField("openType")
will
be SimpleType.INTEGER
.
The Descriptor
for each of these objects will also have a
field originalType
that is a string representing the Java type
that appeared in the MXBean interface. The format of this string
is described in the section Type Names
below.
The Descriptor
for the MBeanInfo
will have a field
mxbean
whose value is the string "true
".
Sometimes the unmapped type T of a method parameter or
return value in an MXBean must be represented as a string. If
T is a non-generic type, this string is the value
returned by Class.getName()
. Otherwise it is the value of
genericstring(T), defined as follows:
Class.getName()
, for example "int"
or "java.lang.String"
.
"[]"
. For example, genericstring(int[]
)
is "int[]"
, and genericstring(List<String>[][]
) is "java.util.List<java.lang.String>[][]"
.
List<String>
and genericstring(T) consists of the
following: the fully-qualified name of the parameterized type as
returned by Class.getName()
; a left angle bracket ("<"
); genericstring(A) where A is the first
type parameter; if there is a second type parameter B
then ", "
(a comma and a single space) followed by
genericstring(B); a right angle bracket (">"
).
Note that if a method returns int[]
, this will be
represented by the string "[I"
returned by Class.getName()
, but if a method returns List<int[]>
,
this will be represented by the string "java.util.List<int[]>"
.
A problem with mapping from Java types to
Open types is signaled with an OpenDataException
. This
can happen when an MXBean interface is being analyzed, for
example if it references a type like java.util.Random
that has no getters. Or it can happen when an
instance is being converted (a return value from a method in an
MXBean or a parameter to a method in an MXBean proxy), for
example when converting from SortedSet<String>
to String[]
if the SortedSet
has a non-null Comparator
.
A problem with mapping to Java types from
Open types is signaled with an InvalidObjectException
.
This can happen when an MXBean interface is being analyzed, for
example if it references a type that is not
reconstructible according to the rules above, in a
context where a reconstructible type is required. Or it can
happen when an instance is being converted (a parameter to a
method in an MXBean or a return value from a method in an MXBean
proxy), for example from a String to an Enum if there is no Enum
constant with that name.
Depending on the context, the OpenDataException
or
InvalidObjectException
may be wrapped in another
exception such as RuntimeMBeanException
or UndeclaredThrowableException
. For every thrown exception,
the condition C will be true: "e is OpenDataException
or InvalidObjectException
(as
appropriate), or C is true of e.getCause()
".

Cuban asylum-seekers: Hunger strikes punished with solitary
by The Associated PressMILAN, N.M. (AP) — A dozen Cuban asylum-seekers detained in a New Mexico say they have repeatedly been placed in solitary confinement for going on hunger strikes.
The Santa Fe New Mexican reports two asylum-seekers in federal immigration custody said they and 10 others were put in solitary confinement twice as punishment for protesting their lengthy stay in prison.
The men are being held at the privately run Cibola County Correctional Center in Milan, New Mexico.
Juan Carlos Peña Pavon told the newspaper he spent nine days in solitary confinement.
The 51-year-old Peña Pavon is part of a group of detained asylum-seekers that last month staged sit-ins at Otero County Processing Center in Chaparral, New Mexico.
A spokeswoman at Immigration and Customs Enforcement’s El Paso field office did not respond to an email.

PIRATES 5992 is a FIRST Robotics Team based in West Orange, New Jersey, with members from both Seton Hall Preparatory School and Mount Saint Dominic Academy. Our main goal is to follow the mission of FIRST by engaging our members in various STEM activites, encouraging students to innovate collectively, and introducing them to a career in STEM.
In 2018, we were very grateful to announce our collaboration with Mount Saint Dominic Academy, an all-girls high school. As Seton Hall Prep is an all-boys school, opening Team 5992 to MSDA marks a significant step in promoting diversity and the women in STEM movement. We firmly believe in equal opportunity for everyone to succeed, and we see sharing our facilities with others as a significant advancement towards achieving this goal.

Life at age twenty seven is nothing what I envisioned when I was a child. I imagined by age twenty seven I would be in a serious relationship border line marriage, owning my own place, a successful career, being financially secure, and living life to the fullest on my downtime. The reality is before college my life was laid out with thirteen years of school then, after college other variables come into play such as figuring out what I want to do in life, coordinating my life with another person’s life, unexpected set backs, and timing.

Currently at age twenty seven, a quarter of what I envisioned, I am on my fifth job, took one year off to figure out what my purpose is in life, currently living with my father, not in a serious relationship, somewhat financially secure, and occasionally live life to my fullest on my downtime. Juggling important parts in my life is a complicated because I want to be well balanced in each category or else if you put too much concentration in one area you might get discourage with the results and burn out. The point is that I did not expect life to be so challenging with many more up hill battles ahead of me.

“Katie's work justice. She made all of our desserts for our wedding: a two-tiered cake, two different flavor combinations of mini cupcakes and four different types of cookies. And let me just tell you, we probably should have placed a bigger order. Our guests went NUTS over the dessert-table selection.”
“Not only was Katie extremely easy to work with, but her prices were very reasonable and the work she did was of professional quality. I sent her a picture of what we had in mind for our wedding cake, and she nailed it perfectly.”

The team will soon be experimenting with a different kind of camping, Hot Tent Camping. Don’t worry, we aren’t planning on restarting the Carry On… franchise. Hot tent camping involves the use of a stove to provide warmth to the tent in particularly cold conditions. It is most often used for semi permanent setups in permanently cold conditions such as way up in North Canada. In these types of setups, specialist equipment is absolutely essential, eh. Amongst such equipment is typically a large and predictably heavy log burning stove.
We’re not a group to go spending money on expensive equipment where it isn’t warranted, especially if it’s for some crackpot idea that might only be a one time use. So, we went about making our own prototype, of sorts.
The product spec was simple: up-cycle materials to make a small, lightweight, portable log burning stove with a chimney which can be attached to a hole in the camping canopy. We got thinking, what would be a good size item for the main chamber? We needed to find something which could take the heat of a 250°C fire, was fairly light and just the right size; not too big, not too small. Our solution was found in another one of the team’s shared hobbies, drinking beer.
Many supermarkets and microbreweries sell mini kegs which hold around 5 litres of beer. We wagered that one of these would be ideal as the starting point and first building block for our lightweight stove.
With a plethora of spare materials and some roughly sketched plans we would have promptly begun construction, except for one small problem.  Fortunately, with the help of my dad (whom was kindly providing use of workshop and many provisions), that issue was swiftly resolved.
First, we needed to make a hole in the top of the keg to make room for a chimney. Looking at the wide selection of tools available to us we chose our weapon and quickly found that the stainless steel keg cut like butter at the hands of most sharp edges, especially a quickly oscillating jigsaw blade. After drilling several pilot holes we cut an opening in the top and folded in the lips. Following our theme of a low budget scrapheap challenge, we then inserted our next part, an old baked bean can for the chimney. After some gentle coercion this fit as snug as a bug in a rug.
Next, we needed to cut a hole and make some kind of door mechanism which would be simple to make but also easy to place and remove when the stove is burning away. The team sketched up a few different ideas and eventually settled upon the idea of placing a door, consisting of an appropriately shaped piece of sheet aluminium, on a small lip at the top of an opening.
We then gutted the belly of the beast, drilling out the dispenser nozzle and several ventilation holes around the bottom, which would hopefully provide some draw of air. We also cut out the aluminum door and attached some wire to act as hook. Finally we cut out and bent some strips of aluminium to act as stage to hold the firewood above the bottom of the keg.
I swear that whenever the Boldly Goes team gets together, we end up making a fire; this occasion was no exception. We loaded the mini-keg stove with paper and kindling, lit the fire and put on the door. Within a minute the fire was roaring and an impressive draw was pulling the flame out the top of the old baked bean can chimney. We kept adding more kindling to the fire and quickly found that we had made a very hungry little stove indeed; it will tear through its maximum capacity of kindling in about five minutes flat. After which, the stove is quickly cool to the touch.
We burnt the stove for about 20 minutes in an attempt to burn off any of the paint or surface finishes on the keg which may produce noxious fumes. Investigating the state of the stove after it had cooled down we’d found that it had adopted a rustic blackened tinge inside and out. We also found that our aluminum fire stage inside had not survived the intense heat of the fire and had curled away to a thin wisp. Considering our creation and testing fairly successful, we’re now ready to incorporate this into a hot tent setup.

About Me
I am 2nd year Computer Science and Engineering student studying at Babaria institute of Techonology, Vadodara.
I like to explore this world and dive straight into the activities which interests me. Working with the moto of
'cut the clutter', I try to focus on building skillset related to these activities one by one. I believe that success is a vector Quantity i.e.
its DIRECTION is as important as its MAGNITUDE.
"KNOW SOMETHING ABOUT EVERITHING AND KNOW EVERITHING ABOUT SOMETHING."
I keep my self up-to-date with latest Techonological Advancement in Computer Science and keep updating my skills accordingly. I prefer 'learnig by doing',so I make projects while I am learning a paticular skill to understand and learn it throughly.

Brave young Irish woman battling rare spinal cord infection
by IrishCentral StaffA brave young Irish woman from Westmeath is fighting a rare spinal infection which has left her unable to walk.
Chloe Greene, 24, from Mullingar, no longer has movement in her left leg after contracting CNS Aspergillosis, an extremely rare fungal infection of the spinal cord, The Irish Mirror reports.
It is believed she came down with the infection while recovering from a stroke she suffered shortly after graduating from college in NUI Galway.

Green, who has ulcerative colitis, already has a compromised immune system from the medication she takes for her condition.
Her family are now looking for treatment option in the UK and the US, and a GoFundMe page has been set up to cover treatment costs.
On the fundraising page, her sister said: "She's had numerous surgeries, the most recent one five weeks ago has left her with no movement in her left leg, unable to walk.
"This infection has eluded the doctors for quite a while and they are now sending her overseas to seek other experts advice and treatment options."
Donations will be used for extra costs incurred while going overseas and towards her rehabilitation.
Her sister added: "Chloe is a kind, generous and loving girl, as anyone who has met her knows.

"She is the first to reach out and help others in their time of need, even when she was sick herself.
"Chloe has shown huge amounts of strength and positivity throughout this long illness. She is a warrior, but now she needs your help in this battle."
So far the campaign has raised €38,278 ($42,300) out of a goal of €100,000.

Factorial Frequencies
问题描述 :
In an attempt to bolster her sagging palm-reading business, Madam Phoenix has decided to offer several numerological treats to her customers. She has been able to convince them that the frequency of occurrence of the digits in the decimal representation of factorials bear witness to their futures. Unlike palm-reading, however, she can’t just conjure up these frequencies, so she has employed you to determine these values.
Recall that the definition of n! (that is, n factorial) is just 1x2x3x…xn. As she expects to use the day of the week, the day of the month, or the day of the year as the value of n, you must be able to determine the number of occurrences of each decimal digit in numbers as large as 366 factorial (366!), which has 781 digits.
输入:
The input data for the program is simply a list of integers for which the digit counts are desired. All of these input values will be less than or equal to 366 and greater than 0, except for the last integer, which will be zero. Don’t bother to process this zero value; just stop your program at that point.
输出:
The output format isn’t too critical, but you should make your program produce results that look similar to those shown below.
样例输入:
3 8 100 0
样例输出:
3! -- (0) 0 (1) 0 (2) 0 (3) 0 (4) 0 (5) 0 (6) 1 (7) 0 (8) 0 (9) 0 8! -- (0) 2 (1) 0 (2) 1 (3) 1 (4) 1 (5) 0 (6) 0 (7) 0 (8) 0 (9) 0 100! -- (0) 30 (1) 15 (2) 19 (3) 10 (4) 10 (5) 14 (6) 19 (7) 7 (8) 14 (9) 20
解题代码:
方法一: import java.util.*; import java.math.*; public class Main{ public static void main(String args[]) throws Exception { Scanner cin=new Scanner(System.in); while(true){ int n=cin.nextInt(); if(n==0) break; BigInteger ans=BigInteger.valueOf(1); for(int i=1;i<=n;i++) ans=ans.multiply(BigInteger.valueOf(i)); char []s=ans.toString().toCharArray(); int []num=new int[10]; for(int i=0;i< s.length;i++){ num[s[i]-'0']++; } System.out.println(n+"! --"); System.out.printf(" (0)%5d (1)%5d (2)%5d (3)%5d (4)%5d\n (5)%5d (6)%5d (7)%5d (8)%5d (9)%5d\n",num[0],num[1],num[2],num[3],num[4],num[5],num[6],num[7],num[8],num[9]); } } } 方法二: import java.io.BufferedInputStream; import java.math.BigDecimal; import java.util.Scanner; public class Main{ public static void main(String[] args) { Scanner scan = new Scanner(new BufferedInputStream(System.in)); while (scan.hasNext()) { int n = scan.nextInt(); if (n == 0) { break; } BigDecimal a = new BigDecimal(n + 1); BigDecimal sum = BigDecimal.ONE; for (BigDecimal i = BigDecimal.ONE; i.compareTo(a) == -1; i = i.add(BigDecimal.ONE)) { sum = sum.multiply(i); } char[] s = sum.toString().toCharArray(); int[] num = new int[10]; for (int i = 0; i < s.length; i++) { num[s[i] - '0']++; } System.out.println(n + "! --"); for (int i = 0; i <= 9; i++) { if (i == 0 | i == 5) { System.out.print(" " + "(" + i + ")"); } else { System.out.print(" " + "(" + i + ")"); } if (num[i] >= 100) { System.out.print(" " + num[i]); } else if (num[i] >= 10) { System.out.print(" " + num[i]); } else { System.out.print(" " + num[i]); } if (i == 4 || i == 9) { System.out.println(""); } } } } }
(adsbygoogle = window.adsbygoogle || []).push({});
这种二分还是比较经典！mark
看见的晚了，只能提交一次唉
3，求得所有的为的总和sum—->所有数的总和
printf( "Not Possible" );—->printf("impossible");
对吗？
aha, welcome!
A的话不是不能避免冲突么？感觉出题者在考察是否考虑了冲突解决办法？
好的，多谢指出

 To this planet comes Ripley and her alien. And Ripley's nightmare starts over. ALIEN 3 will probably kill the series. Director David Fincher's previous major credit is music videos for Madonna. Rating: -1 (-4 to +4).
In 1979 Ridley Scott directed ALIEN. Scott had previously directed the moody story THE DUELLISTS. The inspiration for ALIEN was the weird surrealist paintings of H. R. Giger. The world Giger creates has the feel of an alien culture, the feel of a mind incomprehensible to humans at work. In 1986 James Cameron directed ALIENS. Cameron had directed TERMINATOR. His inspiration was apparently to show how a company of marines reacts when faced with something like the alien threat of the first film. While many of the sequences are lifted from the previous film, Cameron brought complexity to the character of Ripley and had a reasonably complex plot. Now 20th Century Fox has made ALIEN 3. For a director they got David Fincher, who has had a successful career directing music videos and television commercials. The inspiration appears to have been an empty slot at the beginning of the 1992 summer release schedule.
I thought the first film was the best of the series and the second film was a step down. It borrowed whole sequences and ideas from the first film. Also it seemed to sidestep very lightly the moral issue of the earth people stealing and transforming a planet already colonized by an intelligent alien race. It is genuinely surprising and more than a little disturbing how many of the audience were rooting to see the aliens exterminated because they were hostile to humans and not cute and dewy-eyed. Unintentionally, ALIENS was an intriguing test of whether the audience would still buy into attitudes that had caused major foreign policy failures in the past. (And the answer was an undeniably "YES!" Audience cheered ideas as blatant as, "Let's withdraw and nuke 'em from orbit." Perhaps what it showed was that in the end we are just only to those we find appealing.) There were many who preferred the second film for its realistic treatment of marines in space.
The third film is easily the weakest of the three.  The pit is Fury 161, an evacuated lead mine and prison colony. There the worst outcasts of the galaxy have been isolated and have formed a sort of monastic order living in the lead mining facilities. They have no weapons and, to make the place even uglier, they all have to shave their heads because the planet is infested with lice. On this delightful planet crashes Ellen Ripley (played by Sigourney Weaver), the future equivalent of Typhoid Mary. When deaths start occurring on Fury 161, Ripley realizes what she has done but--for reasons never explained--still refers to tell the inhabitants even while people are being killed. Most of the rest of the film is running and screaming through the ugly lead mine.
Fincher has filmed ALIEN 3 with a lot of superficial attempts at style.  One or two scenes with odd camera angles, shooting up or down on characters, would be welcome. Fincher, perhaps used to short music videos, does not seem to know that eventually this becomes very tiresome. The plot takes a long time to advance and in the first half is also short on action. Without sympathy for Ripley from previous films and some minor flashes of humanity from the prison doctor, the film is without sympathetic characters at all. The screenplay is by three people with two different conjunctions: it is by David Giller & Walter Hill and Larry Ferguson.
This is a film that I can recommend only to people into the "Alien" series as a series. (And since this is a third director with a third concept and a third style, this is much more loosely a series than it might be.) As a film it is no better than much of the low-budget productions that show up only on cable. I rate this one a -1 on the -4 to +4 scale.
[Minor spoiler]
The way the alien is killed ranks with one of the most absurd sequences I can think of in a major science fiction film, and is arguably inconsistent with previous entries in the series.

The Newest Star Wars Featurette Is About the Power of Friendship
by Julie MuncySome heartwarming news: the cast members of the new Star Wars trilogy seems to really like each other. Which makes the newest Star Wars: The Rise of Skywalker featurette a joy to watch.
Titled “Friendship,” the new featurette, looking back at the behind-the-scenes history of the franchise, focuses on the intimacy and warmth that exists among the cast and crew of those who created these nine films. In a couple short minutes, it makes the process of creating these films seem like an authentically positive, affirming experience, one that forms lifelong friendships.
It’s also one that features quite a bit of dancing. In the featurette, we see a classic clip of a young Billy Dee Williams slowly grooving, and we also see Daisy Ridley breaking it down while dressed in her Rey getup. Star Wars stories are often about found family and its power, and it’s nice to see that for those who create those stories, that experience might be very real indeed.
The Rise of Skywalker hits cinemas 20th December.

The mission of the Coalition for the Barbados Association of Central Florida (CBAOCF), otherwise known as Central Florida Bajans (CFL Bajans), is to encourage networking and to promote kinship among Barbadians (Bajans) living in Central Florida. Our association maintains avenues of communication between Barbadians in Central Florida and their homeland Barbados, and fosters educational, cultural, and business operations, to further the joint interests of Bajans in both regions in an open, friendly environment.
CFL Bajans help children battling life-threatening illnesses be children.
Give Kids The World Village is a 84 acre, non–profit “story-book” resort, located near Central Florida‘s most beloved attractions, where children with life-threatening illnesses and their families are treated to weeklong, cost- free fantasy vacations.
The story of Give Kids The World began with a little girl with a wish and the desire of one man to make that wish come true. Amy had leukemia and one wish - to visit the theme parks in Orlando. To facilitate Amy's wish, the request of a complimentary stay was made to a respected hotelier. As he had done many times before, the hotelier gladly obliged and Amy's wish was that much closer to being realized. Sadly, the remainder of Amy's travel plans took too long to arrange and her wish was never granted; Amy had passed away. Time simply ran out.
The Coalition for the Barbados Association of Central Florida and the Barbados Association of Tampa Bay adopted 2 villas at Give Kids the World Village. Members of both associations share their time and talents to decorate, landscape and maintain these buildings that our special families call home while on their dream vacation.

Falcon Concept
Source: Cannonman
1. Basic Information
Bullets Per Cycle: 4
Main Bullet Strength (Front): 100% BTE
Main Bullet Strength (Rear): 0.225 BTE
Bullet Speed: 200% BTE
Recoil Per Cycle: 300% BTE
Reload Per Cycle: 50% BTE
Upgrade Path
Basic → Flank Guard → Tri-Angle → Falcon
2. Tank Details
The Falcon is a lvl 45 upgrade off of Tri-Angle. Upon upgrading the front cannon is replaced with a sniper cannon, and an extra cannon is added at the rear. It has more maneuverability than fighter due to the extra recoil, but less than booster. This class primarily focuses on mid-to-long range hit and run attacks, where a few shots are landed and then you retreat to a better position.
3. Builds
0/0/0/6/7/6/7/7
Standard glass build. Play like a normal glass Fighter or Tri-Angle. Remember that you have your back cannon to assist you when running. Your double bullet speed is cruicial in times like this, as you can easily snipe chasing enemies such as Spikes just by getting them to chase you from a little further away.
0/0/2/4/7/6/7/7
Standard Ice Build, lots of speed and a little health to tank a few hits. Play conservatively like a glass build to maximize effectiveness. You are designed to hit and run, but you can take a little damage too. Remember not to be too agressive, even with your health. Use your double bullet speed to your advantage, your 4 bullet speed is equal to 7 on a Fighter. Aim from a distance and play safe.


WordCamp Niagara 2018
Style guide for the WordCamp Niagara 2018 theme
Style guide
Style guide is broken down into several specific groups:
- Overview — Introduction
- Settings — Global variables and examples: colors, typography etc.
- Tools — Default mixins and functions: transitions, global paddings, hidden text etc.
- Generic — Ground–zero styles: normalize.css, global resets, global box-sizing etc.
- Elements — Unclassed HTML elements (type selectors): headings, paragraphs, forms, links etc.
- Objects — Cosmetic–free design patterns
- Components — Designed components and other UI elements that are used to build the theme.
- Trumps — Helpers and overrides.
This style guide is based on KSS methodology.

Niagara-on-the-Lake, Canada - August 11, 2018
Code standards
We are depending on these coding standards for developing flexible, durable, and sustainable HTML and CSS. This mostly affects CSS since HTML of the theme can't be changed without making global breaking changes. But by keeping CSS organized and following a specific writing style — we are making sure that code remains readable and maintainable.
Components
Every component has a static HTML example which helps in keeping the branding consistent.

The Keplerphone is a music generation system powered by the Kepler space telescope. Sonifying astronomical data
may well help to expose the presence of exoplanets, which may be ripe for human conquest at some later point.
Also, interstellar rock.
For a given star (or Kepler object of interest KOI), Kepler provides a time series of light-curve values, chunked up into quarters over a span of roughly two years.
The sonification first detects transiting exoplanets by looking for sharp dips in the light curve, and synthesizes these events as percussion elements. The remaining flux contours are quantized and mapped onto a user-selected scale (e.g., pentatonic). Three quarters of data are played simultaneously with different instrument patches, though the individual time series are not phase aligned for the planet's orbit.
The final sonification is rendered as midi using pretty-midi and played back in the browser with MIDIjs.
Also there are some colorful plots to make it more cheerful. And you can share your favorite space jams with your friends via Twitter.

Every contribution counts and yup mine also did. A cheer moment for me. I finally received the Hacktoberfest swags. My first set of Programming Stickers and the T-Shirt. :)
Just one thing for all the folks who have just entered into Open Source Community. Never judge your contributions with the amount of coding/programming you know. Your contribution could be anything from a line of code, writing documentation, correcting typos, small patches or writing entirely a new feature to the project.
I started because once my mentor taught this to me, and now, I am passing it to you all.
Every small contribution counts, start today !!!


This is a basic backend for key value stores. It receives on initialization the store, which should respond to three methods:
store#[](key) - Used to get a value
store#[]=(key, value) - Used to set a value
storekeys - Used to get all keys
Since these stores only supports string, all values are converted to JSON before being stored, allowing it to also store booleans, hashes and arrays. However, this store does not support Procs.
As the ActiveRecord backend, Symbols are just supported when loading translations from the filesystem or through explicit store translations.
Also, avoid calling I18n.available_locales since it’s a somehow expensive operation in most stores.
To setup I18n to use TokyoCabinet in memory is quite straightforward:
require 'rufus/tokyo/cabinet' # gem install rufus-tokyo I18n.backend = I18n::Backend::KeyValue.new(Rufus::Tokyo::Cabinet.new('*'))
You may make this backend even faster by including the Memoize module. However, notice that you should properly clear the cache if you change values directly in the key-store.
In most backends, you are allowed to retrieve part of a translation tree:
I18n.backend.store_translations :en, :foo => { :bar => :baz } I18n.t "foo" #=> { :bar => :baz }
This backend supports this feature by default, but it slows down the storage of new data considerably and makes hard to delete entries. That said, you are allowed to disable the storage of subtrees on initialization:
I18n::Backend::KeyValue.new(@store, false)
This is useful if you are using a KeyValue backend chained to a Simple backend.


Empty Catch Block finds instances where an exception is caught, but nothing is done. In most circumstances, this swallows an exception which should either be acted on or reported.
