Shrewsbury's Welsh Bridge to close for repair work
by Lucy TodmanShrewsbury's Welsh Bridge will be closed for eight hours overnight to allow repair works to be carried out.
The bridge which links Frankwell with the town centre, will be closed to vehicles from 8pm on December 1 until 4am on December 2.
The work will involve repairing a dislodged section of the upstream left parapet, and some removal of general vegetation.
The bridge carries the A458 over the River Severn, Shrewsbury.
The bridge must be closed to traffic while repairs are being undertaken, as the road is too narrow to for the work to be carried out safely with the bridge open to traffic.
During the road closure, traffic will be diverted via the B4386, B4380, A5191,A5112, A458/A5191, with reverse diversion via A5191, A459, A5112, B4380 and B4386.
Access for pedestrians and dismounted cyclists will remain available at the bridge throughout the work.

NEWS.md
composite_ppi()
(#389)This release is primarily a hotfix for R version 4.0 (#375). All issues included in this release can be found here. New features and improvements include:
regularize_vpts()
is now much faster, and chooses more intuitive starting and ending point of the regularized grid, e.g. projecting on half hour grid will have time series start on the nearest half hour (#332).
regularize_vpts()
has new option keep_timestamp
, which allows individual profiles to keep there original timestamp instead of the timestamp of the regularized grid.
sunrise()
/sunset()
have improved documentation (#180) and new option force_tz
(4968019).
check_night()
has new option offset
, which allows day/night transition to be shifted by a temporal offset (#338). For example, this is useful when selecting night time profiles that start a specific number of hours after sunset.
check_night()
now works for vpi objects (23def64).
filter_vpts()
allows to select for day and night in vpts using new arguments night
, elev
and offset
, based on functionality of check_night()
(#345).
New functions noy()
and doy()
to determine which night or day of the year a profile belongs to (#346).
as.data.frame.vp()
now has separate function page and deprecated parameter quantities
(#364).
get_quantity()
now has improved documentation and allows to return height (#352).
dim()
now returns dimensions in a different, more logical order for pvol and vpts objects (#355).
Improved documentation and unit tests for a number of functions thanks to an online bioRad sprint.
Minor bugfixes. All issues included in this release can be found here. This release primarily fixes a bug that will become effective once R version 4.0 is released.
Fixes a conflict due to new raw data format introduced in R version 4.0 (#331).
Corrects incorrect values in reading of correlation coefficient values RHOHV (#328).
Bugfix in read_cajun()
which introduced incorrect height column during refactoring in bioRad 0.5.0 release (93ad0a4).
Bugfix that fixes the mapping by map()
of composites of composites (ppi’s produced after repeated application of composite_ppi()
, a5c9048, 043aa73).
Minor bug fixes, and addressing conflicts with CRAN dependencies.
Extend the functionality of composite_ppi()
and improve its documentation (partial fix of #59).
Fix a bug in the color legend of map()
when providing a custom color scale with palette argument (#324).
Minor documentation improvements.
New CRAN release. All issues included in this release can be found here.
integrate_to_ppi()
is a new function to estimate spatial images of vertically integrated density and reflectivity. This function produces an ppi
image showing the density of animals on the earth’s surface, corrected for the changing overlap between the radar beams and animal layer with distance from the radar. See Kranstauber et al. 2020 for methodology and this vignette for examples.
apply_mistnet()
is a new function to apply the convolution neural network “MistNet” on pvolfiles to separate biological and meteorological signals (see Lin et al. 2019). Results can be readily visualized with plot.ppi()
and plot.scan()
. MistNet is now also a segmentation option in calculate_vp()
(#262).
read_pvolfile()
and calculate_vp()
now read Vaisala IRIS RAW format directly, helpful for countries like 🇨🇦🇫🇮🇨🇴🇵🇹 (#222). bioRad now also reads files containing single elevation scans and calculate_vp()
can calculate profiles from multiple files containing single elevation scans (#221).
calculate_param()
is a new function to calculate parameters from existing parameters, e.g. reflectivity eta
from reflectivity factor DBZH
(#287).
scan_to_raster()
is a new function to convert a scan
into a RasterBrick
compatible with package raster (#238).
scan_to_spatial()
is a new function to convert a scan
into a SpatialPointsDataFrame
compatible with package sp (#238).
project_as_ppi()
is now much faster (e420e5d) and accounts for earth’s curvature (820e85f).
beam_distance()
and beam_range()
are new functions to relate range (i.e. slant range), distance (i.e. down range) and height of the radar beam.
beam_profile()
is a new function to calculate for a set of beam elevations the altitudinal normalized distribution of radiated energy by those beams.
beam_profile_overlap()
is a new function to calculate the distribution overlap (in terms of Bhattacharyya distance) between a vertical profile (vp
) and the vertical radiation profile of a set of emitted radar beams (given by beam_profile()
).
nyquist_velocity()
is a new function to calculate the unambiguous velocity of Doppler radar from its pulse repetition frequency/frequencies (#208).
filter_vpts()
is a new function simplifying the selection of time ranges and instances in vertical profile time series (vpts
) (#241).
The definition of height-integrated velocity is now corrected (#232, #233, 72be6d1).
Improved documentation of how mtr can be calculated from vid, u, v (6dce625).
read_pvolfile()
now also reads quantities DBZ, TH, T, because these often occur in European data and are relevant for biological analysis (note that DBZ and T are not ODIM-compliant names) (5db08bd).
plot.scan()
now has correct ordering of rays (#285).
plot.vpts()
now has correctly positioned and rounded speed barbs (#277, #244).
integrate_profile()
’s default unit of interval argument has been changed to seconds (#234).
project_as_ppi()
’s default projection is now on earth’s surface (#280).
height
is now the default quantity denoting height above mean sea level. HGHT
is deprecated (#273).
plot.vpts()
and plot.vp()
plots are shifted up by half the height interval to reflect that height refers to the bottom of the height interval (#277, #198).
calculate_vp()
’s default sd_vvp_threshold
parameter value at S-band is now 1 m/s (#93).
And many small bug fixes and documentation improvements.
First release on CRAN! All issues included in this release can be found here.
get_param()
added as new function to get parameters from scan (#132).
download_basemap()
now uses Stamen basemaps by default (parameter source
), so users do not need to request an API key for the previous default Google Maps (#163).
download_vpfiles()
and select_vpfiles()
now use 5 letter radar codes (parameter radars
instead of radar
and country
), allow to skip already downloaded files (parameter overwrite = TRUE
) and have improved download and error messages (#176).
read_pvolfile()
, nexrad_to_odim()
and calculate_vp()
(all Docker dependent) can now read files from directories containing a space (#162).
Details for deprecated functions mt()
, mtr()
, cmt()
are now displayed with function (#166).
Get started vignette is now based on figure and workflow from Dokter et al. (#168).
Introductory exercises vignette renamed to rad_aero_19.Rmd
since it is based on the 3d Radar Aeroecology Training School.
bioRad now has a code of conduct and contributing guidelines (#145).
Release consistent with and in preparation of the bioRad methods paper (https://doi.org/10.1111/ecog.04028). All issues included in this release can be found here.
Functions (#84), arguments (#112) and objects (#80) have been renamed to be consistent (#51). Deprecated functions will remain functional for now, but we will trigger a warning: we advise to use the new functions names. See the lists for current functions and deprecated functions.
integrate_profile()
replaces the functionality of cmt()
(#75) and mt()
(#76).
plot()
can now be used for scans (#71), e.g. plot(example_scan)
.
Functions are organized in sections on the website (#110).
Changelog section (this page) has been added to website (#144).
Package R code is reorganized as one function = one file for easier maintenance (#50).
First tests are included for some functions.
bioRad now has a hex logo (#137). ✨

The Bean Introspection Utilities component of the Apache Commons subproject offers low-level utility classes that assist in getting and setting property values on Java classes that follow the naming design patterns outlined in the JavaBeans Specification, as well as mechanisms for dynamically defining and accessing bean properties.
The JavaBeans name comes from a Java API for a component architecture for the Java language. Writing Java classes that conform to the JavaBeans design patterns makes it easier for Java developers to understand the functionality provided by your class, as well as allowing JavaBeans-aware tools to use Java's introspection capabilities to learn about the properties and operations provided by your class, and present them in a visually appealing manner in development tools.
The JavaBeans Specification describes the complete set of characteristics that makes an arbitrary Java class a JavaBean or not -- and you should consider reading this document to be an important part of developing your Java programming skills. However, the required characteristics of JavaBeans that are important for most development scenarios are listed here:
String className = ...; Class beanClass = Class.forName(className); Object beanInstance = beanClass.newInstance();
get
or set
as the
prefix for the property name with it's first character capitalized. Thus,
you a JavaBean representing an employee might have
(among others) properties named firstName
,
lastName
, and hireDate
, with method signatures
like this:
public class Employee { public Employee(); // Zero-arguments constructor public String getFirstName(); public void setFirstName(String firstName); public String getLastName(); public void setLastName(String lastName); public Date getHireDate(); public void setHireDate(Date hireDate); public boolean isManager(); public void setManager(boolean manager); public String getFullName(); }
is
prefix instead of a get
prefix if that makes
for a more understandable method name.fullName
property is read-only, because there is no
setter method. It is also possible, but less common, to provide
write-only properties.BeanInfo
class associated with
your bean class. See the JavaBeans Specification for full details.Using standard Java coding techniques, it is very easy to deal with JavaBeans if you know ahead of time which bean classes you will be using, and which properties you are interested in:
Employee employee = ...; System.out.println("Hello " + employee.getFirstName() + "!");
The commons-beanutils package requires that the following additional packages be available in the application's class path at runtime:
Furthermore, if any of the following commons-beanutils classes are used:
then the following packages must also be available in the application's class path at runtime:
As described above, the standard facilities of the Java programming language
make it easy and natural to access the property values of your beans using
calls to the appropriate getter methods.
But what happens in more sophisticated environments where you do not
necessarily know ahead of time which bean class you are going to be using,
or which property you want to retrieve or modify? The Java language provides
classes like java.beans.Introspector
, which can examine a Java
class at runtime and identify for you the names of the property getter and
setter methods, plus the Reflection capabilities to dynamically call
such a method. However, these APIs can be difficult to use, and expose the
application developer to many unnecessary details of the underlying structure
of Java classes. The APIs in the BeanUtils package are intended to simplify
getting and setting bean properties dynamically, where the objects you are
accessing -- and the names of the properties you care about -- are determined
at runtime in your application, rather than as you are writing and compiling
your application's classes.
This is the set of needs that are satisfied by the static methods of the PropertyUtils class, which are described further in this section. First, however, some further definitions will prove to be useful:
The general set of possible property types supported by a JavaBean can be broken into three categories -- some of which are supported by the standard JavaBeans specification, and some of which are uniquely supported by the BeanUtils package:
int
, a simple
object (such as a java.lang.String
), or a more complex
object whose class is defined either by the Java language, by the
application, or by a class library included with the application.java.util.List
(or an implementation of List) to be
indexed as well.java.util.Map
to be "mapped". You can set and
retrieve individual values via a String-valued key.A variety of API methods are provided in the PropertyUtils class to get and set property values of all of these types. In the code fragments below, assume that there are two bean classes defined with the following method signatures:
public class Employee { public Address getAddress(String type); public void setAddress(String type, Address address); public Employee getSubordinate(int index); public void setSubordinate(int index, Employee subordinate); public String getFirstName(); public void setFirstName(String firstName); public String getLastName(); public void setLastName(String lastName); }
Getting and setting simple property values is, well, simple :-). Check out the following API signatures in the Javadocs:
Using these methods, you might dynamically manipulate the employee's name in an application:
Employee employee = ...; String firstName = (String) PropertyUtils.getSimpleProperty(employee, "firstName"); String lastName = (String) PropertyUtils.getSimpleProperty(employee, "lastName"); ... manipulate the values ... PropertyUtils.setSimpleProperty(employee, "firstName", firstName); PropertyUtils.setSimpleProperty(employee, "lastName", lastName);
For indexed properties, you have two choices - you can either build a subscript into the "property name" string, using square brackets, or you can specify the subscript in a separate argument to the method call:
Only integer constants are allowed when you add a subscript to the property name. If you need to calculate the index of the entry you wish to retrieve, you can use String concatenation to assemble the property name expression. For example, you might do either of the following:
Employee employee = ...; int index = ...; String name = "subordinate[" + index + "]"; Employee subordinate = (Employee) PropertyUtils.getIndexedProperty(employee, name); Employee employee = ...; int index = ...; Employee subordinate = (Employee) PropertyUtils.getIndexedProperty(employee, "subordinate", index);
In a similar manner, there are two possible method signatures for getting and setting mapped properties. The difference is that the extra argument is surrounded by parentheses ("(" and ")") instead of square brackets, and it is considered to be a String-value key used to get or set the appropriate value from an underlying map.
You can, for example, set the employee's home address in either of these two manners:
Employee employee = ...; Address address = ...; PropertyUtils.setMappedProperty(employee, "address(home)", address); Employee employee = ...; Address address = ...; PropertyUtils.setMappedProperty(employee, "address", "home", address);
In all of the examples above, we have assumed that you wished to retrieve the value of a property of the bean being passed as the first argument to a PropertyUtils method. However, what if the property value you retrieve is really a Java object, and you wish to retrieve a property of that object instead?
For example, assume we really wanted the city
property of the
employee's home address. Using standard Java programming techniques for direct
access to the bean properties, we might write:
String city = employee.getAddress("home").getCity();
The equivalent mechanism using the PropertyUtils class is called nested property access. To use this approach, you concatenate together the property names of the access path, using "." separators -- very similar to the way you can perform nested property access in JavaScript.
The PropertyUtils equivalent to the above Java expression would be:
String city = (String) PropertyUtils.getNestedProperty(employee, "address(home).city");
Finally, for convenience, PropertyUtils provides method signatures that accept any arbitrary combination of simple, indexed, and mapped property access, using any arbitrary level of nesting:
which you might use like this:
Employee employee = ...; String city = (String) PropertyUtils.getProperty(employee, "subordinate[3].address(home).city");
The PropertyUtils class described in the preceding section is designed to provide dynamic property access on existing JavaBean classes, without modifying them in any way. A different use case for dynamic property access is when you wish to represent a dynamically calculated set of property values as a JavaBean, but without having to actually write a Java class to represent these properties. Besides the effort savings in not having to create and maintain a separate Java class, this ability also means you can deal with situations where the set of properties you care about is determined dynamically (think of representing the result set of an SQL select as a set of JavaBeans ...).
To support this use case, the BeanUtils package provides the
DynaBean interface, which must be implemented by a
bean class actually implementing the interface's methods, and the associated
DynaClass interface that defines the set of
properties supported by a particular group of DynaBeans, in much the same way
that java.lang.Class
defines the set of properties supported by
all instances of a particular JavaBean class.
For example, the Employee
class used in the examples above
might be implemented as a DynaBean, rather than as a standard JavaBean. You
can access its properties like this:
DynaBean employee = ...; // Details depend on which // DynaBean implementation you use String firstName = (String) employee.get("firstName"); Address homeAddress = (Address) employee.get("address", "home"); Object subordinate = employee.get("subordinate", 2);
One very important convenience feature should be noted: the
PropertyUtils property getter and setter methods understand how to access
properties in DynaBeans. Therefore, if the bean you pass as the first
argument to, say, PropertyUtils.getSimpleProperty()
is really a
DynaBean implementation, the call will get converted to the appropriate
DynaBean getter method transparently. Thus, you can base your application's
dynamic property access totally on the PropertyUtils APIs, if you wish, and
use them to access either standard JavaBeans or DynaBeans without having to
care ahead of time how a particular bean is implemented.
Because DynaBean and DynaClass are interfaces, they may be implemented multiple times, in different ways, to address different usage scenarios. The following subsections describe the implementations that are provided as a part of the standard BeanUtils package, although you are encouraged to provide your own custom implementations for cases where the standard implementations are not sufficient.
BasicDynaBean
and BasicDynaClass
The BasicDynaBean and BasicDynaClass implementation provides a basic set of dynamic property capabilities where you want to dynamically define the set of properties (described by instances of DynaProperty). You start by defining the DynaClass that establishes the set of properties you care about:
DynaProperty[] props = new DynaProperty[]{ new DynaProperty("address", java.util.Map.class), new DynaProperty("subordinate", mypackage.Employee[].class), new DynaProperty("firstName", String.class), new DynaProperty("lastName", String.class) }; BasicDynaClass dynaClass = new BasicDynaClass("employee", null, props);
Note that the 'dynaBeanClass' argument (in the constructor of
BasicDynaClass
) can have the value of null
. In this
case, the value of dynaClass.getDynaBeanClass
will just be the
Class
for BasicDynaBean.
Next, you use the newInstance()
method of this DynaClass to
create new DynaBean instances that conform to this DynaClass, and populate
its initial property values (much as you would instantiate a new standard
JavaBean and then call its property setters):
DynaBean employee = dynaClass.newInstance(); employee.set("address", new HashMap()); employee.set("subordinate", new mypackage.Employee[0]); employee.set("firstName", "Fred"); employee.set("lastName", "Flintstone");
Note that the DynaBean class was declared to be
DynaBean
instead of BasicDynaBean
. In
general, if you are using DynaBeans, you will not want to care about the
actual implementation class that is being used -- you only care about
declaring that it is a DynaBean
so that you can use the
DynaBean APIs.
As stated above, you can pass a DynaBean instance as the first argument
to a PropertyUtils
method that gets and sets properties, and it
will be interpreted as you expect -- the dynamic properties of the DynaBean
will be retrieved or modified, instead of underlying properties on the
actual BasicDynaBean implementation class.
ResultSetDynaClass
(Wraps ResultSet in DynaBeans)A very common use case for DynaBean APIs is to wrap other collections of
"stuff" that do not normally present themselves as JavaBeans. One of the most
common collections that would be nice to wrap is the
java.sql.ResultSet
that is returned when you ask a JDBC driver
to perform a SQL SELECT statement. Commons BeanUtils offers a standard
mechanism for making each row of the result set visible as a DynaBean,
which you can utilize as shown in this example:
Connection conn = ...; Statement stmt = conn.createStatement(); ResultSet rs = stmt.executeQuery ("select account_id, name from customers"); Iterator rows = (new ResultSetDynaClass(rs)).iterator(); while (rows.hasNext()) { DynaBean row = (DynaBean) rows.next(); System.out.println("Account number is " + row.get("account_id") + " and name is " + row.get("name")); } rs.close(); stmt.close();
RowSetDynaClass
(Disconnected ResultSet as DynaBeans)Although ResultSetDynaClass
is
a very useful technique for representing the results of an SQL query as a
series of DynaBeans, an important problem is that the underlying
ResultSet
must remain open throughout the period of time that the
rows are being processed by your application. This hinders the ability to use
ResultSetDynaClass
as a means of communicating information from
the model layer to the view layer in a model-view-controller architecture
such as that provided by the Struts
Framework, because there is no easy mechanism to assure that the result set
is finally closed (and the underlying Connection
returned to its
connection pool, if you are using one).
The RowSetDynaClass
class represents a different approach to
this problem. When you construct such an instance, the underlying data is
copied into a set of in-memory DynaBeans that represent the result.
The advantage of this technique, of course, is that you can immediately close
the ResultSet (and the corresponding Statement), normally before you even
process the actual data that was returned. The disadvantage, of course, is
that you must pay the performance and memory costs of copying the result data,
and the result data must fit entirely into available heap memory. For many
environments (particularly in web applications), this tradeoff is usually
quite beneficial.
As an additional benefit, the RowSetDynaClass
class is defined
to implement java.io.Serializable
, so that it (and the
DynaBeans that correspond to each row of the result) can be conveniently
serialized and deserialized (as long as the underlying column values are
also Serializable). Thus, RowSetDynaClass
represents a very
convenient way to transmit the results of an SQL query to a remote Java-based
client application (such as an applet).
The normal usage pattern for a RowSetDynaClass
will look
something like this:
Connection conn = ...; // Acquire connection from pool Statement stmt = conn.createStatement(); ResultSet rs = stmt.executeQuery("SELECT ..."); RowSetDynaClass rsdc = new RowSetDynaClass(rs); rs.close(); stmt.close(); ...; // Return connection to pool List rows = rsdc.getRows(); ...; // Process the rows as desired
WrapDynaBean
and WrapDynaClass
OK, you've tried the DynaBeans APIs and they are cool -- very simple
get()
and set()
methods provide easy access to all
of the dynamically defined simple, indexed, and mapped properties of your
DynaBeans. You'd like to use the DynaBean APIs to access all
of your beans, but you've got a bunch of existing standard JavaBeans classes
to deal with as well. This is where the
WrapDynaBean (and its associated
WrapDynaClass) come into play. As the name
implies, a WrapDynaBean is used to "wrap" the DynaBean APIs around an
existing standard JavaBean class. To use it, simply create the wrapper
like this:
MyBean bean = ...;  What makes these flavors of DynaBean lazy are the following features:
DynaClass
which implements
the MutableDynaClass
interface. This provides the ability to add and remove a DynaClass's
properties. Lazy beans use this feature to automatically add
a property which doesn't exist to the DynaClass when
the set(name, value)
method is called.index
being set then the List
or
Array
is automatically grown so that it is.get(name, index)
or
set(name, index, value)
) results in either a new List
or Array
being instantiated. If the indexed property has not been
defined in the DynaClass then it is automatically added and a default List
implementation instantiated.get(name, key)
or
set(name, key, value)
) results in a new Map
being instantiated. If the mapped property has not been defined in the DynaClass
then it is automatically added and a default Map
implementation
instantiated.DynaClass
as a DynaBean
or regular bean and
doesn't exist in the DynaBean
then LazyDynaBean
wiill
try to instantiate the bean using a default empty constructor.1. LazyDynaBean is the standard lazy bean
implementation. By default it is associated with a LazyDynaClass
which implements the MutableDynaClass interface - however
it can be used with any MutableDynaClass
implementation. The question is how do
I use it? - well it can be as simple as creating a new bean and then calling the getters/setters...
DynaBean dynaBean = new LazyDynaBean(); dynaBean.set("foo", "bar"); // simple dynaBean.set("customer", "title", "Mr"); // mapped dynaBean.set("customer", "surname", "Smith"); // mapped dynaBean.set("address", 0, addressLine1); // indexed dynaBean.set("address", 1, addressLine2); // indexed dynaBean.set("address", 2, addressLine3); // indexed
2.  Its light weight because it doesn't
have an associated DynaClass
containing all the properties. In fact it actually implements
the DynaClass
interface itself (and MutableDynaClass
) and derives all the DynaClass
information from the actual contents of the Map
. A LazyDynaMap
can be created around an
existing Map
or can instantiate its own Map
. After any DynaBean
processing has finished the Map
can be retrieved and the DynaBean facade discarded.
If you need a new Map
then to use....
DynaBean dynaBean = new LazyDynaMap(); // create DynaBean dynaBean.set("foo", "bar"); // simple dynaBean.set("customer", "title", "Mr"); // mapped dynaBean.set("address", 0, addressLine1); // indexed Map myMap = dynaBean.getMap() // retrieve the Map
or to use with an existing Map
....
Map myMap = .... // exisitng Map DynaBean dynaBean = new LazyDynaMap(myMap); // wrap Map in DynaBean dynaBean.set("foo", "bar"); // set properties
3. LazyDynaList is lazy list for DynaBean's,
java.util.Map
's or POJO beans. See the Javadoc for more details and
example usage.
4. LazyDynaClass extends BasicDynaClass
and implements the MutableDynaClass interface. It can be used with other
DynaBean
implementations, but it is the default DynaClass
used by LazyDynaBean
.
When using the LazyDynaBean
there may be no need to have anything to do with the DynaClass
However sometimes there is a requirement to set up the DynaClass
first - perhaps to
define the type of array for an indexed property, or if using the DynaBean in restricted mode (see note below)
is required. Doing so is straight forward...
Either create a LazyDynaClass
first...
MutableDynaClass dynaClass = new LazyDynaClass(); // create DynaClass dynaClass.add("amount", java.lang.Integer.class); // add property dynaClass.add("orders", OrderBean[].class); // add indexed property dynaClass.add("orders", java.util.TreeMapp.class); // add mapped property DynaBean dynaBean = new LazyDynaBean(dynaClass); // Create DynaBean with associated DynaClass
or create a LazyDynaBean
and get the DynaClass
...
DynaBean dynaBean = new LazyDynaBean(); // Create LazyDynaBean MutableDynaClass dynaClass = (MutableDynaClass)dynaBean.getDynaClass(); // get DynaClass dynaClass.add("amount", java.lang.Integer.class); // add property dynaClass.add("myBeans", myPackage.MyBean[].class); // add 'array' indexed property dynaClass.add("myMap", java.util.TreeMapp.class); // add mapped property
NOTE: One feature of MutableDynaClass is that it
has a Restricted property. When the DynaClass is restricted no properties can be added
or removed from the DynaClass
. Neither the LazyDynaBean
or LazyDynaMap
will add properties automatically if the DynaClass
is restricted.
So far, we've only considered the cases where the data types of the dynamically accessed properties are known, and where we can use Java casts to perform type conversions. What happens if you want to automatically perform type conversions when casting is not possible? The BeanUtils package provides a variety of APIs and design patterns for performing this task as well.
BeanUtils
and ConvertUtils
ConversionsA very common use case (and the situation that caused the initial creation
of the BeanUtils package) was the desire to convert the set of request
parameters that were included in a
javax.servlet.HttpServletRequest
received by a web application
into a set of corresponding property setter calls on an arbitrary JavaBean.
(This is one of the fundamental services provided by the
Struts Framework, which uses
BeanUtils internally to implement this functionality.)
In an HTTP request, the set of included parameters is made available as a
series of String (or String array, if there is more than one value for the
same parameter name) instances, which need to be converted to the underlying
data type. The BeanUtils class provides
property setter methods that accept String values, and automatically convert
them to appropriate property types for Java primitives (such as
int
or boolean
), and property getter methods that
perform the reverse conversion. Finally, a populate()
method
is provided that accepts a java.util.Map
containing a set of
property values (keyed by property name), and calls all of the appropriate
setters whenever the underlying bean has a property with the same name as
one of the request parameters. So, you can perform the all-in-one property
setting operation like this:
HttpServletRequest request = ...; MyBean bean = ...; HashMap map = new HashMap(); Enumeration names = request.getParameterNames(); while (names.hasMoreElements()) { String name = (String) names.nextElement(); map.put(name, request.getParameterValues(name)); } BeanUtils.populate(bean, map);
The BeanUtils
class relies on conversion methods defined in
the ConvertUtils class to perform the actual
conversions, and these methods are availablve for direct use as well.
WARNING - It is likely that the hard coded use of
ConvertUtils
methods will be deprecated in the future, and
replaced with a mechanism that allows you to plug in your own implementations
of the Converter interface instead. Therefore,
new code should not be written with reliance on ConvertUtils.
The ConvertUtils
class supports the ability to define and
register your own String --> Object conversions for any given Java class.
Once registered, such converters will be used transparently by all of the
BeanUtils
methods (including populate()
). To
create and register your own converter, follow these steps:
convert()
method should accept the
java.lang.Class
object of your application class (i.e.
the class that you want to convert to, and a String representing the
incoming value to be converted.ConvertUtils.register()
method.The standard classes in org.apache.commons.beanutils
are not
locale aware. This gives them a cleaner interface and makes then easier to use
in situations where the locale is not important.
Extended, locale-aware analogues can be found in
org.apache.commons.beanutils.locale
. These are built along the same
lines as the basic classes but support localization.
So far, the examples have covered the static utility classes (BeanUtils
,
ConvertUtils
and PropertyUtils
). These are easy to use but are
somewhat inflexible. These all share the same registered converters and the same caches.
This functionality can also be accessed through utility objects (in fact, the static utility class use worker instances of these classes). For each static utility class, there is a corresponding class with the same functionality that can be instantiated:
| Static Utility Class | Utility Object |
|---|---|
| BeanUtils | BeanUtilsBean |
| ConvertUtils | ConvertUtilsBean |
| PropertyUtils | PropertyUtilsBean |
Creating an instances allow gives guarenteed control of the caching and registration to the code that creates it.
org.apache.commons.beanutils.BeanComparator
is a Comparator
implementation
that compares beans based on a shared property value.
The Closure
interface in commons-collections
encapsulates a block of code that
executes on an arbitrary input Object. Commons-collections
contains code that allows
Closures
to be applied to the contents of a Collection. For more details, see the
commons-collections
documentation.
BeanPropertyValueChangeClosure
is a Closure
that sets a specified property
to a particular value. A typical usage is to combine this with commons-collections
so that all the beans in a collection can have a particular property set to a particular value.
For example, set the activeEmployee property to TRUE for an entire collection:
// create the closure
BeanPropertyValueChangeClosure closure =
new BeanPropertyValueChangeClosure( "activeEmployee", Boolean.TRUE );
// update the Collection
CollectionUtils.forAllDo( peopleCollection, closure );
The Predicate
interface in commons-collections
encapsulates an evaluation
of an input Object that returns either true or false. Commons-collections
contains code
that allows
Predicates
to be applied to be used to filter collections. For more details, see the
commons-collections
documentation.
BeanPropertyValueEqualsPredicate
is a Predicate
that evaluates a
set property value against a given value. A typical usage is
(in combination with commons-collections
)
to filter collections on the basis of a property value.
For example, to filter a collection to find all beans where active employee is false use:
BeanPropertyValueEqualsPredicate predicate =
new BeanPropertyValueEqualsPredicate( "activeEmployee", Boolean.FALSE );
// filter the Collection
CollectionUtils.filter( peopleCollection, predicate );
The Transformer
interface in commons-collections
encapsulates the transformation
of an input Object into an output object. Commons-collections
contains code
that allows
Transformers
to be applied produce a collection of outputs from a collection of inputs.
For more details, see the
commons-collections
documentation.
BeanToPropertyTransformer
is a Transformer
implementation
that transforms a bean into it's property value.
For example, to find all cities that are contained in the address of each person property of each bean in
a collection:
// create the transformer
BeanToPropertyValueTransformer transformer = new BeanToPropertyValueTransformer( "person.address.city" );
// transform the Collection
Collection peoplesCities = CollectionUtils.collect( peopleCollection, transformer );
The BeanUtils package relies on introspection rather than reflection. This means that it will find only JavaBean compliant properties.
There are some subtleties of this specification that can catch out the unwary:
java.beans.Introspector
searches widely for a custom BeanInfo
class. If your class has the same name as another with a custom BeanInfo
(typically a java API class) then the Introspector
may use that instead of
creating via reflection based on your class. If this happens, the only solution is to
create your own BeanInfo.
BeanComparator relies on an internal Comparator to perform the actual
comparisions. By default,
org.apache.commons.collections.comparators.ComparableComparator
is used which imposes a natural order. If you want to change the order,
then a custom Comparator should be created and passed into the
appropriate constructor.
For example:
import org.apache.commons.collections.comparators.ComparableComparator;
import org.apache.commons.collections.comparators.ReverseComparator;
import org.apache.commons.beanutils.BeanComparator;
...
BeanComparator reversedNaturalOrderBeanComparator
= new BeanComparator("propertyName", new ReverseComparator(new ComparableComparator()));
Collections.sort(myList, reversedNaturalOrderBeanComparator);
...

Services
Introduction
What are Services?
The Services in CodeIgniter 4 provide the functionality to create and share new class instances.
It is implemented as the Config\Services
class.
All of the core classes within CodeIgniter are provided as “services”. This simply means that, instead of hard-coding a class name to load, the classes to call are defined within a very simple configuration file. This file acts as a type of factory to create new instances of the required class.
Why use Services?
A quick example will probably make things clearer, so imagine that you need to pull in an instance of the Timer class. The simplest method would simply be to create a new instance of that class:
<?php
$timer = new \CodeIgniter\Debug\Timer();
And this works great. Until you decide that you want to use a different timer class in its place. Maybe this one has some advanced reporting the default timer does not provide. In order to do this, you now have to locate all of the locations in your application that you have used the timer class. Since you might have left them in place to keep a performance log of your application constantly running, this might be a time-consuming and error-prone way to handle this. That’s where services come in handy.
Instead of creating the instance ourself, we let a central class create an instance of the class for us. This class is kept very simple. It only contains a method for each class that we want to use as a service. The method typically returns a shared instance of that class, passing any dependencies it might have into it. Then, we would replace our timer creation code with code that calls this new class:
<?php
$timer = \Config\Services::timer();
When you need to change the implementation used, you can modify the services configuration file, and the change happens automatically throughout your application without you having to do anything. Now you just need to take advantage of any new functionality and you’re good to go. Very simple and error-resistant.
Note
It is recommended to only create services within controllers. Other files, like models and libraries should have the dependencies either passed into the constructor or through a setter method.
How to Get a Service
As many CodeIgniter classes are provided as services, you can get them like the following:
<?php
$typography = \Config\Services::typography();
The $typography
is an instance of the Typography class, and if you call \Config\Services::typography()
again, you will get the exactly same instance.
The Services typically return a shared instance of the class. The following code creates a CURLRequest
instance at the first call. And the second call returns the exactly same instance.
<?php
$options1 = [
'baseURI' => 'http://example.com/api/v1/',
'timeout' => 3,
];
$client1 = \Config\Services::curlrequest($options1);
$options2 = [
'baseURI' => 'http://another.example.com/api/v2/',
'timeout' => 10,
];
$client2 = \Config\Services::curlrequest($options2);
// $options2 does not work.
// $client2 is the exactly same instance as $client1.
Therefore, the parameter $options2
for the $client2
does not work. It is just ignored.
Getting a New Instance
If you want to get a new instance of the Typography class, you need to pass false
to the argument $getShared
:
<?php
$typography = \Config\Services::typography(false);
Convenience Functions
Two functions have been provided for getting a service. These functions are always available.
service()
The first is service()
which returns a new instance of the requested service. The only
required parameter is the service name. This is the same as the method name within the Services
file always returns a SHARED instance of the class, so calling the function multiple times should
always return the same instance:
<?php
$logger = service('logger');
// The code above is the same as the code below.
$logger = \Config\Services::logger();
If the creation method requires additional parameters, they can be passed after the service name:
<?php
$renderer = service('renderer', APPPATH . 'views/');
// The code above is the same as the code below.
$renderer = \Config\Services::renderer(APPPATH . 'views/');
single_service()
The second function, single_service()
works just like service()
but returns a new instance of
the class:
<?php
$logger = single_service('logger');
// The code above is the same as the code below.
$logger = \Config\Services::logger(false);
Defining Services
To make services work well, you have to be able to rely on each class having a constant API, or interface, to use. Almost all of CodeIgniter’s classes provide an interface that they adhere to. When you want to extend or replace core classes, you only need to ensure you meet the requirements of the interface and you know that the classes are compatible.
For example, the RouteCollection
class implements the RouteCollectionInterface
. When you
want to create a replacement that provides a different way to create routes, you just need to
create a new class that implements the RouteCollectionInterface
:
<?php
namespace App\Router;
use CodeIgniter\Router\RouteCollectionInterface;
class MyRouteCollection implements RouteCollectionInterface
{
// Implement required methods here.
}
Finally, add the routes()
method to app/Config/Services.php to create a new instance of MyRouteCollection
instead of CodeIgniter\Router\RouteCollection
:
<?php
namespace Config;
use CodeIgniter\Config\BaseService;
class Services extends BaseService
{
// ...
public static function routes()
{
return new \App\Router\MyRouteCollection(static::locator(), config('Modules'));
}
}
Allowing Parameters
In some instances, you will want the option to pass a setting to the class during instantiation. Since the services file is a very simple class, it is easy to make this work.
A good example is the renderer
service. By default, we want this class to be able
to find the views at APPPATH . 'views/'
. We want the developer to have the option of
changing that path, though, if their needs require it. So the class accepts the $viewPath
as a constructor parameter. The service method looks like this:
<?php
namespace Config;
use CodeIgniter\Config\BaseService;
class Services extends BaseService
{
// ...
public static function renderer($viewPath = APPPATH . 'views/')
{
return new \CodeIgniter\View\View($viewPath);
}
}
This sets the default path in the constructor method, but allows for easily changing the path it uses:
<?php
$renderer = \Config\Services::renderer('/shared/views/');
Service Discovery
CodeIgniter can automatically discover any Config/Services.php files you may have created within any defined namespaces. This allows simple use of any module Services files. In order for custom Services files to be discovered, they must meet these requirements:
Its namespace must be defined in app/Config/Autoload.php
Inside the namespace, the file must be found at Config/Services.php
It must extend
CodeIgniter\Config\BaseService
A small example should clarify this.
Imagine that you’ve created a new directory, Blog in your project root directory. This will hold a Blog module with controllers, models, etc, and you’d like to make some of the classes available as a service. The first step is to create a new file: Blog/Config/Services.php. The skeleton of the file should be:
<?php
namespace Blog\Config;
use CodeIgniter\Config\BaseService;
class Services extends BaseService
{
public static function postManager()
{
// ...
}
}
Now you can use this file as described above. When you want to grab the posts service from any controller, you
would simply use the framework’s Config\Services
class to grab your service:
<?php
$postManager = \Config\Services::postManager();
Note
If multiple Services files have the same method name, the first one found will be the instance returned.

Dear Partner, With great pleasure, I am writing this proposal for the benefit of both of us. I got your information through my personal search on the internet, hence I decided to seek your cooperation, due to the sensitivity of this transaction and my commitment as a Banker. My name is Mr. Charles Sherman (British Citizen), I work for FDTB London / Germany. Mr. Raymond Beck, an American Citizen, Engineer by profession who died since 1999, in an Egyptin Airline (Flight 990), on the 31st October along with other passengers on board. For your perusal,you can confirm this from the website below:- http://www.s-t.com/daily/11-99/11-02-99/d08ho174.htm Before his death, he has a huge sum of money (US$35 Millions), which I was his account officer until his death. This money has no other Beneficiary or Next of Kin. Since his death in 1999, none of his family member or Next of Kin has come forward to claim this funds as no one has the knowledge that he had such amount deposited in our bank. As the account officer to the Late Mr. Raymond Beck, I secured from the Probate an Order of Mandamus to locate any of the deceased Beneficiaries to enable the bank release this fund, before the fund will be called back to the bank Treasury as unclaimed bills and the money will be shared amongst the Directors of the Bank. My constraint is to be able to source a foreigner partner who is honest and trustworthy individual, that I will present to the bank as his Next of Kin / Beneficiary of the said funds (US$35,000,000.00) This transaction is 100% risk free provided you treat it with utmost secrecy and confidentiality, as I had also made arrangment with an Attorney that will provide all the needed documentation in your favour. I am ready to compensate you with 30%, while I receives 60% and the balance of (10%) for taxes and other miscellaneous expenses. Furthermore, your area of specialization is not a hindrance to the successful execution of this transaction. Kindly contact me through this email address<EMAIL_ADDRESS>with the following information(s). 1. Your first and last names 2. Complete Home address 3. Direct Telephone and fax numbers. 4. Age, Sex and Marital Status. Thank you and God Bless, MR. CHARLES SHERMAN.

I love design
Hello and welcome to my website! Recently, I attended the International HRI conferece hosted at Vienna Austria. I also completed an internship at Marquette University working in the HEIR Lab as a Research Assistant aiding the design of a “tutoring robot” Being creative and solving new challenges are what I enjoy the most in design. For example; learning how to design this website. Whether its drawing, working in CAD, or talking to users, there is never really a dull moment when designing. I am currently employed as an industrial designer for Winnebago Industries.

Research
I primarily study methods for missing data treatment. I also collaborate extensively with social-, behavioral-, and health-scientists.
My research generally falls into one of two broad categories: methodological work developing and evaluating methods to treat missing data or collaborations with substantive researchers from the social-, behavioral-, and health-sciences.
In my methodological work, I mostly explore ways of treating missing data (i.e., data with values in the population but unobserved entries in the sample). Missing values cause myriad problems for statistical modeling, inference, and prediction, so treating missing data is a crucial step in any data analysis. Currently, my work focuses on developing and evaluating multiple imputation techniques. In particular, I am interested in ways of simplifying the process of specifying the underlying imputation models.
In my substantive collaborations, I provide statistical expertise to research teams from social-, behavioral-, and health-sciences. For example, in this project, I helped design a novel planned missing data protocol for non-survey data; in this project, I helped evaluate the efficacy of the Kansas Intensive Permanency Project, and in this project, I helped develop norms for the Supports Intensity Scale. I particularly enjoy collaboration because I like contributing to a group effort, and the diversity of research topics keeps things interesting. As such, I have to agree with John Tukey’s purported quip:
The best thing about being a statistician is that you get to play in everyone’s backyard.
I strive to follow open-science principles in my work. So, open-access flavors of most of my published work are available via the Utrecht University Repository, my Google Scholar profile, or my ResearchGate page.

Nyzo version 505 (commit on GitHub) introduces a verifier-performance rating.
This version only affects the verifier, but it does not affect the behavior of the verifier in a significant way. Upgrading to this version is optional.
Since the introduction of the sentinel, verifiers have been able to stay in the cycle even when they have performance or stability issues. While the sentinel is a valuable tool to keep the cycle from losing verifiers, over-reliance on it can lead to performance issues for the cycle at large. A verifier scoring system is necessary to ensure that verifiers that continually under-perform to the detriment of the cycle are eventually removed from the cycle.
Due to the remarkable efforts of the community in proactively improving verifier performance, this verifier-rating system is not as urgent of a need as it seemed to be several days ago. To avoid unfairly removing verifiers that are attempting to maintain proper performance, this version does not yet use verifier- performance scores to remove under-performing verifiers from the cycle. Removal based on these performance scores will be implemented soon.
In the MeshListener class, the new PerformanceScoreStatusRequest418 message type produces a PerformanceScoreStatusResponse. Also, unrelated to verifier performance scores, the ResetRequest500 message, which resets the internal verifier state and restarts the verifier, has been changed to only respond to messages signed by the local verifier. Previously, this mechanism could be triggered by messages signed by the same private key that signed the Genesis block. It was a convenience that we used in testing, and we intended to remove it before release.
In the processContent() method of the Message class, building of the PerformanceScoreStatusResponse from byte buffers has been added. When a Nyzo message is received, the numerical type of the message is checked, and this method deserializes the object if there is one associated with the type.
In the MessageType enumeration, PerformanceScoreStatusRequest418 and PerformanceScoreStatusResponse419 have been added, and the note to change the key for the reset message has been removed.
The Verifier class updates the VerifierPerformanceManager scores each time a block is frozen.
The VerifierPerformanceManager is a simple class with a simple scoring system. Higher numerical scores indicate poorer verifier performance, and lower numerical scores indicate better verifier performance. Each time a block is frozen, the score of every verifier increases by 3. However, the score of each verifier that voted for the block that was just frozen then decreases by 6. So, if this verifier is receiving votes for at least 50% of blocks from another verifier, then the score of that other verifier will remain stable or improve on this verifier.
The printScores() method of VerifierPerformanceManager class is used for writing the score file and for the PerformanceScoreStatusResponse content. Each identifier and score are written on a single line, and a comment adds the nickname to improve readability. Scores are written from high to low, so the poorest-performing verifiers are at the top of the list.
The PerformanceScoreStatusResponse is a standard multi-line text response. As only in-cycle verifiers are scored, the size of this response is guaranteed to grow slowly.
The functionality of the ConsensusTallyStatusRequestScript has been refactored into the fetchMultilineStatus() method of ScriptUtil class. This method is used by the ConsensusTallyStatusRequestScript and the new PerformanceScoreStatusRequestScript.
These scripts work for both local and remote queries. To run the PerformanceScoreStatusRequestScript script on your verifier, ssh to the verifier, navigate to the nyzoVerifier directory, and run the following command:
sudo java -jar build/libs/nyzoVerifier-1.0.jar co.nyzo.verifier.scripts.PerformanceScoreStatusRequestScript
If you want to run the script from a system that is not an in-cycle verifier, provide the private seed of an in-cycle verifier. The script will query verifier0.nyzo.co to obtain the current mesh, and it will find your verifier in the mesh and send a self-signed message to it. The command for this is similar to the previous command:
sudo java -jar build/libs/nyzoVerifier-1.0.jar co.nyzo.verifier.scripts.PerformanceScoreStatusRequestScript [seed of in-cycle verifier]


Plants
iGEM introduced an award for plant synthetic biology for the first time in 2016. Many teams have worked in this area over the years, and we finally decided it was time for a special award to encourage teams in this area. Teams can work with a number of different plant and algal chassis to be eligible for this award. The prize will go to the team with the best plant synthetic biology project. As with all awards, if there are a sufficiently high number of participating teams, there will be separate awards for the undergraduate and overgraduate sections.
While not mandatory, teams are strongly encouraged to work with Phytobricks during your project.


Previously, I worked as a Java backend developer for Zextras were I developed a cloud storage solution and a WebRTC videochat, both serving users in many organizations using Zimbra and now I'm focused on the WebRTC videochat portion for our new product, Carbonio.
I've also worked at H-Benchmark were I helped developing a data intelligence web application whose goal is to help hospitality get better by analyzing data and giving insights on how a single structure and its territory are performing.
My thesis aimed at creating an Android application (both the application and all the backend structure) to aid users' prospectic memory, a particular type of memory which allows people to remember things that needs to happen in the future like buying milk before getting back home.
This application uses Natural Language Processing to retrieve the user's requests, allowing him/her to define a task using only natural language. The backend then automatically figures where and when to complete the task.
I'm contributing to yap, a forked tool that allows you to build packages for many GNU/Linux distributions with a single package definition.
Moreover, I also took part in the ProtonDB crowdsourced translation.

Looks like iSkoot made a mistake with their Nokia S60 client and will make it right. Apparently a non-production version of the S60 client made it to the public web, which sends data in the clear. Other published versions of their client on other platforms are unaffected.
iSkoot CEO Mark Jacobstein says the existing S60 build will be pulled. The bug will be fixed and a forced upgrade to a patched version will be pushed.
Thanks to Andy Abramson and Jim Courtney for their behind-the-scenes help with this. Update: Forgot to thank Dan York as well, who helped despite spending the weekend driving a U-Haul. :)
