This visualisation depicts the interactions among characters in The Lord of the Rings: The Return of The King movie.
Despite the fact that Sam and Frodo are (arguablly) the two key roles in the last movie of the The Lord of the Rings trilogy, their number of interaction is only slighly higher than the interaction between Gandalf and Pippin. Gandalf and Pippin played significant roles in the siege of Minas Tirith scenes.
Two node clusters are apparent in the network. These clusters are facinating depictions of the two parallel stories in the movie. One story is about the journey to the Mount Doom that Frodo, Sam, and Gollum undertook, while the other story is about the wars that took place in Minas Tirith and Mordor.

Love you Ten thousand years
问题描述 :
Love you Ten thousand years——Earth’s rotation is a day that is the representative of a day I love you. True love, there is no limit and no defects. Earth’s revolution once a year, it is on behalf of my love you more than a year. Permanent horizon, and my heart will never change ……
We say that integer x, 0 < x < n,(n is a odd prime number) is a LovePoint-based-on n if and only if the set { (xi mod n) | 1 <= i <= n-1 } is equal to { 1, …, n-1 }. For example, the powers of 3 modulo 7 are 3, 2, 6, 4, 5, 1, and thus 3 is a LovePoint-based-on 7.
Now give you a integer n >= 3(n will not exceed 231).
We say the number of LovePoint-based-on n is the number of days the earth rotating.
Your task is to calculate the number of days someone loved you.

C语言版本的代码好像有点问题


We've seen how even just doing two simple operations one after another can get extremely
complex when considering error handling in asynchronous code. We've also seen how promises
help you mitigate this via .then
, which causes errors to bubble up the stack by
default.
In this article we'll cover some of the more advanced patterns for promise use and some of the helper methods to make your Promise code more concise.
Sometimes you already have a value and you want to convert it into a promise. You may also sometimes find yourself with a value that may or may not be a promise. Finally you might find you have a value that is a promise but does not work as it should (e.g. a jQuery promise) and want to convert it into a true promise.
var value = 10;
var promiseForValue = Promise.resolve(value);
// equivalent to
var promiseForValue = new Promise(function (fulfill) {
fulfill(value);
});
var jQueryPromise = $.ajax('/ajax-endpoint');
var realPromise = Promise.resolve(jQueryPromise);
// equivalent to
var realPromise = new Promise(function (fulfill, reject) {
jQueryPromise.then(fulfill, reject);
});
var maybePromise = Math.random() > 0.5 ? 10 : Promise.resolve(10);
var definitelyPromise = Promise.resolve(maybePromise);
// equivalent to
var definitelyPromise = new Promise(function (fulfill, reject) {
if (isPromise(maybePromise)) {
maybePromise.then(fulfill, reject);
} else {
fulfill(maybePromise);
}
});
It's best to always avoid throwing synchronous exceptions in an asychronous method. Always returning a promise has the benefit that people can always handle all errors in the same consistent way. To make it easier to do this, there is a shortcut for generating a rejected promise.
var rejectedPromise = Promise.reject(new Error('Whatever'));
// equivalent to
var rejectedPromise = new Promise(function (fulfill, reject) {
reject(new Error('Whatever'));
});
Trying to do this in parallel only gets more complicated. Consider the following function which attempts to read an array of files (specified by filename) and parse them as JSON then returns the resulting array via a callback:
function readJsonFiles(filenames, callback) {
var pending = filenames.length;
var called = false;
var results = [];
if (pending === 0) {
// we need to return early in the case where there
// are no files to read, but we must not return immediately
// because that unleashes "Zalgo". This makes code very hard
// to reason about as the order becomes increasingly
// non-deterministic.
return setTimeout(function () { callback(); }, 0);
}
filenames.forEach(function (filename, index) {
readJSON(filename, function (err, res) {
if (err) {
if (!called) callback(err);
return;
}
results[index] = res;
if (0 === --pending) {
callback(null, results);
}
});
});
}
That's a maddening amount of code to have to write for such a simple asynchronous function. It is possible to write most of this into a library function that lets you do an asynchronous "map" operation, but that only solves the very specific case, and can still be remarkably fiddly.
The all
function returns a new promise which is fulfilled with an array of fulfillment
values for the passed promises or rejects with the reason of the first promise that rejects.
function readJsonFiles(filenames) {
// N.B. passing readJSON as a function, not calling it with `()`
return Promise.all(filenames.map(readJSON));
}
readJsonFiles(['a.json', 'b.json']).done(function (results) {
// results is an array of the values stored in a.json and b.json
}, function (err) {
// If any of the files fails to be read, err is the first error
});
Promise.all
is a builtin method, so you don't need to worry about implementing it
yourself, but it serves as a nice demo of how easy promises are to work with.
function all(promises) {
var accumulator = [];
var ready = Promise.resolve(null);
promises.forEach(function (promise, ndx) {
ready = ready.then(function () {
return promise;
}).then(function (value) {
accumulator[ndx] = value;
});
});
return ready.then(function () { return accumulator; });
}
What's going on here is that we start by creating a variable to store the result (called
accumulator
) and a variable to denote whether the result is up to date (called
ready
). We wait on ready
, and also update it with each turn of the loop.
This leads to us putting each value
onto the accumulator
array one at a time
in order. By the end of the loop, ready
is a promise that will wait for
all the items to be inserted into the accumulator
array.
All we have to do at the end is wait for the ready
promise and then return accumulator
.
The native implementation will be more efficient than this, but it should give you an idea of how promises can be combined in interesting ways.
Sometimes it is useful to race two promises against each other. Consider the case of writing a timeout function. You could do something like this:
function delay(time) {
return new Promise(function (fulfill) {
setTimeout(fulfill, time);
});
}
function timeout(promise, time) {
return new Promise(function (fulfill, reject) {
// race promise against delay
promise.then(fulfill, reject);
delay(time).done(function () {
reject(new Error('Operation timed out'));
});
});
}
Promise.race makes races like this even easier to run:
function timeout(promise, time) {
return Promise.race([promise, delay(time).then(function () {
throw new Error('Operation timed out');
})]);
}
Whichever promise settles (fulfills or rejects) first wins the race, and determines the result.

Setting up RethinkDB in CentOS and Fedora, NoSQL
Install and Configure RethinkDB - CentOS, Fedora
Difficulty: 2
Time: 20 minutes
This article will guide you through the installation of RethinkDB in CentOS and Fedora. RethinkDB belongs to the NoSQL family that can be easily configured with JSON storage database. It has two components - the database itself and the client driver to access the database from our selected database. You will need sudo
access to complete these steps.
Install the server
- We will add the repositories for RethinkDB yum to the existing list of repositories and then install it using the following command:
sudo wget http://download.rethinkdb.com/centos/6/`uname -m`/rethinkdb.repo \
-O /etc/yum.repos.d/rethinkdb.repo
sudo yum install rethinkdb
- We are done with the RethinkDB installation but we need client drivers as well.
Install the client drivers
- At present official drivers are available for three languages - Javascript, Ruby, and Python. To install Ruby driver, first install rubygems with the following command:
sudo yum install rubygems
- Now install gem
sudo gem install rethinkdb
Now you can start the RethinkDB server with "$ rethinkdb" command.
- To install Javascript driver use the following command:
sudo yum install npm
npm install rethinkdb
- To install Python driver, use the following command:
sudo easy_install pip
sudo pip install rethinkdb
Next Steps
In this article, we have used the binary files to install RethinkDB and its client drivers. However, you can also install them using the source file.


Music Object Version 2.7.9
RELEASE DATE: 1999-01-12
|
|
|
What's New In This Version
|
NEW CLIENT SUPPORTED - WebTV Satellite Receiver
Version 2.7.9 now supports one of the new models of WebTV set-top boxes, known as the "WebTV Satellite Receiver". This is in addition to the "WebTV Plus Receiver", supported since version 2.7.4. Support for the new WebTV product has not added substantially to the size of the "music-object.js" file.
ISSUE WORKAROUND - Unexplained Long Pause in Internet Explorer
An issue was discovered with Microsoft Internet Explorer and the Beatnik ActiveX control. Occasionally, certain pages would pause for a very long time and not complete loading until something happened in the operating system to "tickle" the browser. The problem was traced to the OBJECT tag's HIDDEN parameter and how this was being used in the dummy instance that is necessary to obtain the version number of the installed player. How exactly this causes the problem is unknown.
The solution, for now, requires that the 1 x 1 pixel dummy player instance not be hidden, resulting in a small "speck", usually towards the top left of any sonified document. This speck does not appear in Netscape Navigator because this browser provides a clear way to obtain version information of installed plug-ins without the need to create dummy instances.
ISSUE WORKAROUND - Unreliable Triggering of the onReady Event
It was discovered that certain content behaved erratically and would sometimes work, and sometimes would not. Investigation revealed that event triggering from ActiveX controls is sometimes unreliable and there can be cases where the scripting layer is not successfully initialized and ready to receive events, when the control believes it is OK to trigger the events. The workaround that was put in place involves a kind of "handshake", where Music Object informs the control that it has received the onReady event. The control will continue periodically retriggering the event unless it receives this verification from Music Object.
IMPROVEMENT - Full Meta Event Support in Internet Explorer
For a while, it has been unclear how to receive parameters passed by ActiveX controls firing events to the browser's scripting layer. So, while previous versions of Music Object where receiving meta events from the player, the all important meta event type and meta event value parameters were not being received. Version 2.7.9 now contains code to receive these parameters and pass them to the registered meta event handler.
API CHANGE - getPlatform Method Replaced by mo_platform Attribute
For the longest time, the getPlatform method has simply returned the userAgent property of the browser being used. Since this can easily be done using the "navigator.userAgent" property, it was decided to remove this method from the API. A more useful way to determine the class of browser being used is to use Music Object's mo_platform global variable.
OPTIMIZATION - General Improvements
Some optimizations were made to the inner workings of Music Object to increase its efficiency. None of these code optimizations require any changes to authored content.

MEET WALLY SPARKS A film review by James Berardinelli Copyright 1997 James Berardinelli
RATING (0 TO 10): 1.5 Alternative Scale: 1/2 out of ****
United States, 1997 U.S. Release Date: 1/31/97 (wide) Running Length: 1:45 MPAA Classification: R (Profanity, sexual situations, nudity) Theatrical Aspect Ratio: 1.85:1 Theater: Magic @ Hadley, 1/31/97, 4:15 pm
Cast: Rodney Dangerfield, David Ogden Stiers, Debi Mazar, Mark Taylor, Cindy Williams, Lisa Thornhill, Michael Weatherly, Burt Reynolds Director: Peter Baldwin Producer: Leslie Greif Screenplay: Rodney Dangerfield and Harry Basil Cinematography: Richard H. Kline Music: Michel Colombier U.S. Distributor: Trimark Pictures
Despite his immense popularity on stage, Rodney Dangerfield doesn't have a sterling reputation as a motion picture lead.  MEET WALLY SPARKS, a lame, late-January film dumped into a sluggish market, may well finish the aging comic's screen career. There's nothing in this movie that warrants the price of a video rental, much less a trip to a theater.
Generally, about the best one can hope for from a Dangerfield movie is a cliched storyline filled with crude-but-humorous gags and one- liners. That is, after all, basically what BACK TO SCHOOL delivered, and it worked on that basis. MEET WALLY SPARKS never comes close, because there's hardly a laugh to be found from start to finish. It amazes me that Dangerfield, who in the past has been able to make the simple act of walking into a room funny, has turned out such a dreadful motion picture. MEET WALLY SPARKS is easily among the ten worst comedies I've seen in the past two years.
It's hard to put a finger on why Dangerfield isn't funny here. He certainly doesn't seem to have invested his character, tabloid talkshow host Wally Sparks, with much vitality. The sex jokes, even when you can't see them coming, are old and tired, as if we've heard them a few times too many. This shtick is worn-out; it might still work in comedy clubs, but any spontaneity is lost on screen. And, unfortunately, the one or two potentially-amusing moments have been shown to death in the previews, so their comic effect is ruined. Even Dangerfield's intention of lampooning the current generation of talk shows isn't successful. In spite of numerous cameos (by the likes of Geraldo, Morton Downey Jr., Jerry Springer, Bob Saget, Roseanne, Michael Bolton, Ron Jeremy, Tony Danza, Tim Allen, Jay Leno, and others), MEET WALLY SPARKS is too absurd to retain any sense of verisimilitude. Without that quality, there's little chance for satire to be effective. Yet probably the worst thing about WALLY SPARKS is its failed attempts to inject character development and human interest into a one-dimensional story.
The sole bright spot is the opening montage, which compares THE WALLY SPARKS SHOW to its moderate TV competitors (GERALDO, OPRAH, etc.) by means of quick edits. Once the credits have concluded, however, it's all downhill -- fast. The film's premise involves Wally toning down his show to stem the tide of deserting sponsors. The network president (Burt Reynolds) gives him one week to clean up his act, or he's off the air. The show's producer, a no-nonsense woman named Sandy (Debi Mazar), decides that Wally's best chance at respectability is to get his longtime opponent, conservative Governor Preston of Georgia (David Ogden Stiers), as a guest. Complications ensue when the talkshow host is injured at one of Preston's parties. And, as if that wasn't enough, Sparks becomes an unwitting player in a scheme to blackmail the governor.
Enduring MEET WALLY SPARKS is akin to watching a multi-car pileup, as each successive failure leads to a bigger thud. By the end of the movie, I didn't know whether to feel angry at being subjected to such a loathsome experience, or saddened and embarrassed for Dangerfield and the others involved. By his own admission, Rodney's not a happy person, and the public and critical response to MEET WALLY SPARKS isn't likely to bring much sunshine into his life. This is truly a movie that doesn't deserve any respect.

Properties
Methods
_lazyInjections
()
Object
Returns a hash of property names and container names that injected properties will lookup on the container lazily.
Returns:
Hash of all lazy injected property keys to container names
_onLookup
()
private
Provides lookup-time type validation for injected properties.
_scheduledDestroy
()
private
Invoked by the run loop to actually destroy the object. This is
scheduled for execution by the destroy
method.
create
-
[arguments]
Creates an instance of a class. Accepts either no arguments, or an object containing values to initialize the newly instantiated object with.
App.Person = Ember.Object.extend({
helloWorld: function() {
alert("Hi, my name is " + this.get('name'));
}
});
var tom = App.Person.create({
name: 'Tom Dale'
});
tom.helloWorld(); // alerts "Hi, my name is Tom Dale".
create
will call the init
function if defined during
Ember.AnyObject.extend
If no arguments are passed to create
, it will not set values to the new
instance during initialization:
var noName = App.Person.create();
noName.helloWorld(); // alerts undefined
NOTE: For performance reasons, you cannot declare methods or computed
properties during create
. You should instead declare methods and computed
properties when using extend
or use the createWithMixins
shorthand.
Parameters:
-
[arguments]
Object optional multiple
createWithMixins
-
[arguments]
Equivalent to doing extend(arguments).create()
.
If possible use the normal create
method instead.
Parameters:
-
[arguments]
Object optional multiple
destroy
()
Ember.Object
Destroys an object by setting the isDestroyed
flag and removing its
metadata, which effectively destroys observers and bindings.
If you try to set a property on a destroyed object, an exception will be raised.
Note that destruction is scheduled for the end of the run loop and does not happen immediately. It will set an isDestroying flag immediately.
Returns:
receiver
eachComputedProperty
-
callback
-
binding
Iterate over each computed property for the class, passing its name
and any associated metadata (see metaForProperty
) to the callback.
extend
-
[mixins]
-
[arguments]
Creates a new subclass.
App.Person = Ember.Object.extend({
say: function(thing) {
alert(thing);
}
});
This defines a new subclass of Ember.Object: App.Person
. It contains one method: say()
.
You can also create a subclass from any existing class by calling its extend()
method. For example, you might want to create a subclass of Ember's built-in Ember.View
class:
App.PersonView = Ember.View.extend({
tagName: 'li',
classNameBindings: ['isAdministrator']
});
When defining a subclass, you can override methods but still access the implementation of your parent class by calling the special _super()
method:
App.Person = Ember.Object.extend({
say: function(thing) {
var name = this.get('name');
alert(name + ' says: ' + thing);
}
});
App.Soldier = App.Person.extend({
say: function(thing) {
this._super(thing + ", sir!");
},
march: function(numberOfHours) {
alert(this.get('name') + ' marches for ' + numberOfHours + ' hours.')
}
});
var yehuda = App.Soldier.create({
name: "Yehuda Katz"
});
yehuda.say("Yes"); // alerts "Yehuda Katz says: Yes, sir!"
The create()
on line #17 creates an instance of the App.Soldier
class. The extend()
on line #8 creates a subclass of App.Person
. Any instance of the App.Person
class will not have the march()
method.
You can also pass Mixin
classes to add additional properties to the subclass.
App.Person = Ember.Object.extend({
say: function(thing) {
alert(this.get('name') + ' says: ' + thing);
}
});
App.SingingMixin = Mixin.create({
sing: function(thing){
alert(this.get('name') + ' sings: la la la ' + thing);
}
});
App.BroadwayStar = App.Person.extend(App.SingingMixin, {
dance: function() {
alert(this.get('name') + ' dances: tap tap tap tap ');
}
});
The App.BroadwayStar
class contains three methods: say()
, sing()
, and dance()
.
Parameters:
-
[mixins]
Mixin optional multipleOne or more Mixin classes
-
[arguments]
Object optional multipleObject containing values to use within the new class
init
()
An overridable method called when objects are instantiated. By default, does nothing unless it is overridden during class definition.
Example:
App.Person = Ember.Object.extend({
init: function() {
alert('Name is ' + this.get('name'));
}
});
var steve = App.Person.create({
name: "Steve"
});
// alerts 'Name is Steve'.
NOTE: If you do override init
for a framework class like Ember.View
or
Ember.ArrayController
, be sure to call this._super()
in your
init
declaration! If you don't, Ember may not have an opportunity to
do important setup work, and you'll see strange behavior in your
application.
metaForProperty
-
key
In some cases, you may want to annotate computed properties with additional metadata about how they function or what values they operate on. For example, computed property functions may close over variables that are then no longer available for introspection.
You can pass a hash of these values to a computed property like this:
person: function() {
var personId = this.get('personId');
return App.Person.create({ id: personId });
}.property().meta({ type: App.Person })
Once you've done this, you can retrieve the values saved to the computed property from your class like this:
MyClass.metaForProperty('person');
This will return the original hash that was passed to meta()
.
Parameters:
-
key
Stringproperty name
reopen
()
Augments a constructor's prototype with additional properties and functions:
MyObject = Ember.Object.extend({
name: 'an object'
});
o = MyObject.create();
o.get('name'); // 'an object'
MyObject.reopen({
say: function(msg){
console.log(msg);
}
})
o2 = MyObject.create();
o2.say("hello"); // logs "hello"
o.say("goodbye"); // logs "goodbye"
To add functions and properties to the constructor itself,
see reopenClass
reopenClass
()
Augments a constructor's own properties and functions:
MyObject = Ember.Object.extend({
name: 'an object'
});
MyObject.reopenClass({
canBuild: false
});
MyObject.canBuild; // false
o = MyObject.create();
In other words, this creates static properties and functions for the class. These are only available on the class and not on any instance of that class.
App.Person = Ember.Object.extend({
name : "",
sayHello : function(){
alert("Hello. My name is " + this.get('name'));
}
});
App.Person.reopenClass({
species : "Homo sapiens",
createPerson: function(newPersonsName){
return App.Person.create({
name:newPersonsName
});
}
});
var tom = App.Person.create({
name : "Tom Dale"
});
var yehuda = App.Person.createPerson("Yehuda Katz");
tom.sayHello(); // "Hello. My name is Tom Dale"
yehuda.sayHello(); // "Hello. My name is Yehuda Katz"
alert(App.Person.species); // "Homo sapiens"
Note that species
and createPerson
are not valid on the tom
and yehuda
variables. They are only valid on App.Person
.
To add functions and properties to instances of
a constructor by extending the constructor's prototype
see reopen
toString
()
String
Returns a string representation which attempts to provide more information
than Javascript's toString
typically does, in a generic way for all Ember
objects.
App.Person = Em.Object.extend()
person = App.Person.create()
person.toString() //=> "<App.Person:ember1024>"
If the object's class is not defined on an Ember namespace, it will indicate it is a subclass of the registered superclass:
`
javascript
Student = App.Person.extend() student = Student.create() student.toString() //=> "<(subclass of App.Person):ember1025>"
If the method toStringExtension
is defined, its return value will be
included in the output.
`
javascript
App.Teacher = App.Person.extend({
toStringExtension: function() {
return this.get('fullName');
}
});
teacher = App.Teacher.create()
teacher.toString(); //=> "<App.Teacher:ember1026:Tom Dale>"
Returns:
string representation
willDestroy
()
Override to implement teardown.
Properties
concatenatedProperties
Array
Defines the properties that will be concatenated from the superclass (instead of overridden).
By default, when you extend an Ember class a property defined in
the subclass overrides a property with the same name that is defined
in the superclass. However, there are some cases where it is preferable
to build up a property's value by combining the superclass' property
value with the subclass' value. An example of this in use within Ember
is the classNames
property of Ember.View
.
Here is some sample code showing the difference between a concatenated property and a normal one:
App.BarView = Ember.View.extend({
someNonConcatenatedProperty: ['bar'],
classNames: ['bar']
});
App.FooBarView = App.BarView.extend({
someNonConcatenatedProperty: ['foo'],
classNames: ['foo']
});
var fooBarView = App.FooBarView.create();
fooBarView.get('someNonConcatenatedProperty'); // ['foo']
fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
This behavior extends to object creation as well. Continuing the above example:
var view = App.FooBarView.create({
someNonConcatenatedProperty: ['baz'],
classNames: ['baz']
})
view.get('someNonConcatenatedProperty'); // ['baz']
view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
Adding a single property that is not an array will just add it in the array:
var view = App.FooBarView.create({
classNames: 'baz'
})
view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
Using the concatenatedProperties
property, we can tell Ember to mix the
content of the properties.
In Ember.View
the classNameBindings
and attributeBindings
properties
are also concatenated, in addition to classNames
.
This feature is available for you to use throughout the Ember object model, although typical app developers are likely to use it infrequently. Since it changes expectations about behavior of properties, you should properly document its usage in each individual concatenated property (to not mislead your users to think they can override the property in a subclass).
Default: null
isDestroyed
Unknown
Destroyed object property flag.
if this property is true
the observers and bindings were already
removed by the effect of calling the destroy()
method.
Default: false
isDestroying
Unknown
Destruction scheduled flag. The destroy()
method has been called.
The object stays intact until the end of the run loop at which point
the isDestroyed
flag is set.
Default: false

Charlize Theron won’t ever 'compromise' for a man
by Algoa FMActress Charlize Theron has said she wants to find love again and be in a relationship but she won't ever "compromise" anything in her life to please a man.
"I'd love to meet somebody and that is something I even think can happen. I'm just not willing to compromise if something doesn't feel right. That's something that has definitely changed for me after I got to my forties, Theron told HELLO! magazine, reports femaelfirst.co.uk.
She added: "I think a huge part of my relationships in the past have been about me being hyper-aware that there was an element to me that was threatening to people."
The actress says in her 20s she had the need to modulated herself, depending on the relationship.
"I remember a lot of times thinking, 'If I could just make myself smaller, then this relationship would be perfect.' But the older I get the more I've come to realise that doing that is just not being true to me," she said.
Theron previously dated Sean Penn, whom she began romancing in late 2013 and they announced their engagement in December 2014, however, they eventually split around six months later in 2015.
Prior to Penn, the actress had a long-term relationship with actor Stuart Townsend, after they met of the set of the 2002 movie "Trapped", before calling time on their romance in January 2010.
Rather change anything about herself, Theron, who has two adopted children, August and Jackson, hopes that she will meet a man who loves her for who she is.

In this article we will discuss how to send a fax using WestFax API as well as have the WestFax API send a callback when the fax has completed.
What are callbacks? They are asynchronous, out-of-band requests that your service will send to some other service in response to certain events. This helps you improve the workflow your API. A typical use is for events. You set the callback url which is a page on your website that can process data about an event. Your page is configured to receive parameters using POST or GET Method. WestFax supports both. When an event occurs (Successful fax delivery, etc…) it will call that url with the proper parameters so your application can handle the event and process your workflow without having to intermittently ping our service.
The WestFax API is comprised of a large set of methods that are exposed using a RESTful interface. Data can be interchanged in a number of formats including JSON and XML. Additionally, WestFax offers SOAP and RPC bindings that are described elsewhere. For the purposes of this demo the REST interface with JSON encoding is used.
Click Download or Fork it to your local repo.
Once you have the local files you should see two Json Files: WestFaxApi_Postman_collection.json and WestFaxApiEnvironment.postman_environment.json
Open Postman and create a new Request. You can call it whatever you want to call it but we will use WestFax.
Now go click the File -> Import command.
Drag or select the two Json Files from the code you downloaded earlier and click import.
You will see it quickly import and you will have 23 requests in your new WestFax Collection.
Now look at the top right corner of postman. You should see a drop down and an “eye” icon and a gear icon.
Select the Dropdown to select “WestFaxApiEnvironment” and then click the Eye icon.
 You will want to change these by clicking Edit.
Change the default values to the ones you received when you signed up for API access.
Now let’s go test to make sure we are connecting ok and getting a response from the server. On the left menu under “23 requests” select the “Security_Ping”. Go ahead and click the blue “SEND” button.
You should see something like this come back from the API. If not please feel free to contact us for support.
Now let’s try to send a fax. If you have an incoming number attached to your account you can use that or any other fax number. You can also use the well known HP Faxback test number at 1-888-473-2963. They will fax you back that they received your fax usually within 5 minutes.
So click the Fax_SendFax method on the left and you will see this for your Body setup.
The {{ Orange }} values are filled in from the config you already set so you can ignore those. The values you need to set are the Numbers1, Files0 fields. The rest are optional and you can unclick them if you want. Although adding a FeedbackEmail value is useful to get confirmation of the fax sending. Once you set all these variables go ahead and click send.
(Optional: Callback). Set your CallbackUrl with templated values for replacement. In this case we are using: [get]http://yourweburl.com/{@jobid}?prod={@prodid}&dir={@dir}. WestFax will replace the @jobid, @prodid and @dir with real values so one can process accordingly. GET is implied so you can exclude [get] from the beginning or use [post] to use that method.
You should see a result code of True and a hash string with the confirmation code. This Result code is the @jobid you will use in the next phase of handling the callback so copy this value somewhere.
Ok, so here is a neat trick that Postman give us. You can get all your code done for you. Just click the button “Code”. It’s kind of buried near the Send button next to cookies.
Now when you click code you will get formatted code for almost any programming language you may need:
So the fax process worked and we are waiting for a callback response. Basically WestFax will ping a url that you provide. So let’s assume it is https://yourwebsite.com/
We will pass in some parameters with it using GET or POST. GET is implied so you must specify POST in the callback request if you want it to post to a form. We pass in three pieces of information:
So when the callback fires your webpage should handle those input values.
Once you have the values you can call the next webservice and get the data back. Let’s get started.
Let’s go back to Postman and find the webservice called Fax_GetFaxDescriptionsUsingIds. Go ahead and click it. You’ll see something like this:
Ok, so let’s look at the Body of this request so we know what we need to fill out to get the fax status.
We see that it has the username, password, cookies (we can ignore that), productID and two new fields FaxIds1 and FaxIds2. You’ll notice that these fields have template string placeholders of {{FaxIds1}} and {{FaxIds2}}. This is because these values are serialized and we’ll look at this next. The FaxIds fields are the Faxes we want to get the status of. We have the result code from the previous call so let’s go explore that.
We are going to click on the Pre-request Script header and we’ll see the format of the template placeholder we talked about previously.
So we already put this code in there for you. All you need to do is replace the Id field. The Direction, Date and Tag are optional as the ID is the key field here. So we’ll put our Id in here and you can see on Line 8 that we bind the JSON string to the Variable. You could also copy all the JSON from the variable id1 into the FaxIds1 field directly but this template allows you to append more Id’s and get the status of several faxes.
Once you have the ID in there you will hit Send and get the following output.
You can see here that we have a complete record of the fax transmission. You can parse the JSON result in whatever method you choose and you can see that we have the Date, Direction, PageCount, Quality and Status which is Complete. So the fax is completed.
Success! As you can see it’s not hard at all to add Faxing to your Enterprise application. If you have questions or need more help please reach out to us at<PHONE_NUMBER> or contact us via email.

[gecode-users] Why are my variables not constrained
Max

Sun Oct 5 13:59:41 CEST 2008
Thank you very much, it now works as intended. Great !
I hope i will get along with the documentation, it is hard to find
things like tt or eqv or the function how to branch manually or something.
I will keep annoying you if i have further questions.
Thank you all for the help.
Best regards.

The insert block is the block you want to choose, if you want to insert values in your database. It symbolises the insert structure.
Blocks, like tables and operators are plugged in it.
It also can be mutated.
If you want to learn more about how to mutate the block please, see 'Functionality'.
The not mutated select has one input in the 'INTO'-section.
This block also changes the colour, to symbolise the types used in SQL.
To mutate the block, you click on the
star-icon and a new workspace appears.
In this workspace you can drop blocks into an 'ADD'-block to expand the insert-block.
So for each droped block one new input appears. Like you see in the picture above.
If you want to reduce the number of inputs, you click on the star icon and pull the blocks out of the 'ADD' block.
The block in this workspace symbolises the'INTO' statement.
In the section 'Statement' you will learn more about them.
In the mutator workspace there ist one block symbolising the 'INTO'-statement in SQL.
The 'INTO' input uses the compare operator.
Into the first input of the compare operator, you need to plug in the tables and columns value, used here as the insert destination.
As second input value your need a value, corresponding in type and colour to the first input.
This is shown in the picture above. Be sure to use only
tables and columns you use in the 'INSERT'-section,
otherwise there will be a warning.
Be sure the you use only the same table in the insert Block.
The usage of different Tables is not provided.
This colour gradient, apple green to cyan, symbolises a list of columns of the database
This colour gradient, violet to cyan, symbolises the numeric values of the database
This colour gradient, brown to cyan, symbolises the textual values of the database
This colour gradient ,tapestry to cyan, symbolises the date values of the database
This colour ,cyan, symbolises the boolean values of the database

Preamble aside, Valentine’s Day was not always a commercial holiday. Instead, the holiday can be traced back to the Roman Empire. From the third century B.C.E. to fifth century C.E., Roman senators practiced the ritual of Lupercalia.
Every February 15, Roman senators met in the chamber called the Lupercal, which was the supposed birthplace of the mythical founders of Rome, Romulus and Remus. The senators would sacrifice a goat, run through the streets of Rome and strike women with pieces of meat to encourage fertility.
Concurrent to the polytheistic festivals of Rome is the conversion of Constantine the Great. In 312 A.D., Constantine converted to Christianity, changing the state religion from polytheism to Christianity. This began the rise of Christianity and the Papacy in Rome.
In the final years of Lupercalia, Pope Gelasius I declared February 14 Valentine’s Day. The holiday— preceding Lupercalia by one day on the calendar— was meant as a feast day. It was established to honor Saint Valentine.
The story of Saint Valentine varies depending on different accounts, from his attempts to convert the Emperor Claudius II or Roman citizens, in each case leading to his execution. He became the patron of lovers, couples, marriages, beekeepers and epilepsy. This eclectic patronage is a sign that the earliest Valentine’s Day celebrations were not focused on love, but a veneration of the saint through festival focused on a feast.
It wasn’t until the time of Geoffrey Chaucer that the word “Valentine” was associated with ideas of love. In his poem “Parlement of Foules,” Chaucer first connected the Valentine with ideas of love.
Valentine’s Day would change once again into the commercialized holiday that we have come to know with the advent of the Industrial Revolution. The era of mass-production allowed for Valentine’s Day cards to be produced in mass quantities, rather than hand made.
In the current moment, Valentine’s Day has become an equally commercialized and romanticized holiday. The tension of finding love and purchasing gifts has become the subject of parody, even being reinterpreted as Single Awareness Day, or SAD. Internationally the holiday more broadly encompasses love for one’s friends as well as partners, like El día del Amor y Amistad.
Looking through the history of the holiday, we can see that Valentine’s Day was not always about love. Instead, it is a holiday with traditions deeply rooted in the celebration of relations from lovers to friends to family.

Use common fairness metrics and an interactive dashboard to assess which groups of people may be negatively impacted.
Use state-of-the-art algorithms to mitigate unfairness in your classification and regression models.
Fairlearn provides developers and data scientists with capabilities to assess the fairness of their machine learning models and mitigate unfairness. Assess existing models and train new models with fairness in mind. Compare models and make trade-offs between fairness and model performance.
Wide selection of fairness metrics and state-of-the-art mitigation algorithms
Open API that’s easy to access and supports standard machine learning algorithms
Assess unfairness and compare multiple models for side-by-side analysis
There are many ways that an AI system can behave unfairly. Fairlearn focuses on negative impacts for groups of people, such as those defined in terms of race, gender, age, or disability status.
For example, a voice recognition system might fail to work as well for some groups of people as it does for others.
For example, a system for screening loan or job applications might be better at picking good candidates among some groups of people than among others.

--- layout: default title: Princess - Easy to customize Sass library. ---
A lightweight, extendable CSS library built with Sass and Normalize that's blissfully easy to customize.
Princess is inspired by Pure's simplicity and Blueprint's flexibility.
The idea behind Princess is that you receive a set of base styles of primary elements, along with modules that include classes for optional styling, all based on Normalize and two files containing variables. Princess is written in Sass for easy customization and can be used in whole or in parts.
A lot of me has gone into Princess. I like whitespace, big fonts, and smooth CSS transitions. There's even a little module for improving code snippet highlighting in Jekyll! Princess was written because I wanted something I could use for all of my future projects that was already customized and styled to fit my needs. Because I love writing documentation, I decided to package it up for distribution.
The documentation for Princess is styled using Princess.
To download Princess, clone the repository from Git.
Copy the file compiled/princess.css
into your desired directory, and include it in your HTML:
Voila! You have the Normalize base and the full Princess library at your disposal.
The guides are organized according to which section of the Princess library each element belongs to.
Read the first item in each subsection. It contains vital information about that items in that group, and the rest of the documentation assumes you've read it. Generally you're presented with a list first (Variable list, Module list, etc) or a guide to that section (usage, basics).

Should we prove le_of_lt_of_le
so this stuff works?
example {a b c : ℕ} (h : a < b) (h₁ : b ≤ c) : a ≤ c := calc a < b : h ... ≤ c : h₁ @[trans] lemma le_of_lt_of_le {a b c : ℕ} : a < b → b ≤ c → a ≤ c := sorry example {a b c : ℕ} (h : a < b) (h₁ : b ≤ c) : a ≤ c := calc a < b : h ... ≤ c : h₁
I've run into that before
You have to remember to apply le_of_lt before starting the calc :-)
I like the idea.
dammit I want the proof to be le_of_lt $ lt_of_lt_of_le
:-)
λ x y, le_of_lt $ lt_of_lt_of_le x y
looks like you're missing a trick

'If he can blend the two styles together - Warrenball and Pivacball - it could be something special'
by By Online EditorsShane Williams has predicted an exciting era under Wayne Pivac as Wales move on from Warren Gatland’s 12-year reign.
Gatland enjoyed huge success as Wales won four Six Nations titles, three Grand Slams and reached two World Cup semi-finals during his tenure.
But Williams, Wales’ all-time top try scorer and a former world rugby player of the year, believes Pivac will develop a more expansive style to build on Gatland’s success.
“Having spoken to Wayne I know he’s going to put his own stamp on it,” Williams said. “He’s got a lot of expectation on him and big boots to fill. But that’s the personality he is. We’ve already seen that he’s not frightened to make big decisions. He’s going to blood new players and that’s what we want to see in Wales.”
For all his success, Gatland’s style of play – which was termed ‘Warrenball’ – came in for a fair amount of criticism for being too structured and predictable. Former Fiji coach Pivac has been lauded in Wales for the attacking approach he implemented at the Scarlets between 2014 and 2019.
(Continue reading below…)
“Let’s hope there’s a combination of both styles,” said Williams. “Warren’s teams won Grand Slams, even if it wasn’t pretty at times, so they’ve been doing something right.
“But they didn’t win the World Cup so they’re obviously lacking something, and I hope Wayne can fill that gap in between. If he can blend the two styles together – ‘Warrenball’ and ‘Pivacball’ – it could be something special.
“He’s done a great job with the Scarlets, I like the style they’ve played with. They’re very attacking-minded and that’s what we want in Welsh rugby.”
On the end of Gatland’s reign after a fourth-place finish at the 2019 World Cup, Williams added: “Warren said himself that it was time for a change. I know the players – most of whom have only ever played under ‘Gats’ for Wales – can’t wait to see what new ideas Wayne’s going to come in with.”

A step-by-step guide to set up a development environment for working on Folktale.
A step-by-step guide to set up a development environment for working on Folktale.
Configuring a development environment for Folktale is currently a little bit more complicated than it should in some systems, but this guide should help you achieve that anyway.
First of all, you'll have to make sure you have Git installed. Folktale uses Git repositories, and while while you can use things like hg-git to interact with the repository from Mercurial, we can't support that.
The Git website has a list of GUI clients for Git, if you're not comfortable using it from the command line.
Next you'll need to install Node.js. The website provides binaries for all supported platforms. All newer versions of Node come with npm as well, which you'll use to pull the dependencies of the project.
Note that Folktale requires at least Node 4.x, so if you have an older version you'll need to upgrade.
Folktale uses Make as its build system, and also relies on some common *NIX
tools, like find
. Because of this, it might be harder to configure a
development environment for Windows.
Below are instructions to install Make on common systems:
TODO
Provide instructions for OS/X and *BSD systems.
$ apt-get install build-essential
$ pacman -S base-devel
$ yum install "Development Tools"
GetGnuWin32-*.exe
;download.bat
from the folder you extracted the components to;install.bat
from that folder.The first thing you'll want to do is forking Folktale. This means you get a clone of the entire project that you have rights to change as you wish. Once you have forked Folktale, you can clone your fork:
$ git clone https://github.com/YOUR_GITHUB_USERNAME/folktale.git
This will create a folktale
folder containing all of the code in the
project. The first thing you need to do is move in that folder and install all
of the dependencies and development tools that Folktale uses:
$ cd folktale
$ npm install
# Some of the tools are in a git subrepo
$ git submodule init
$ git submodule update
$ make tools


These functions provide ways of working with a region: a data frame with
numeric "left" and "right" columns, each row of which represents a unique
finite interval (open, either type of half-open, or closed). Values of "left"
and "right" columns should create an "ordered" set of intervals:
left[1] <= right[1] <= left[2] <= right[2] <= ...
(intervals with zero
width are accepted). Originally, region_*()
functions were designed to work
with output of summ_hdr()
and summ_interval()
, but can be used for any
data frame which satisfies the definition of a region.
region_is_in(region, x, left_closed = TRUE, right_closed = TRUE)
region_prob(region, f, left_closed = TRUE, right_closed = TRUE)
region_height(region, f, left_closed = TRUE, right_closed = TRUE)
region_width(region)
region_distance(region, region2, method = "Jaccard")
region_draw(region, col = "blue", alpha = 0.2)
| region | A data frame representing region. |
|---|---|
| x | Numeric vector to be tested for being inside region. |
| left_closed | A single logical value representing whether to treat left ends of intervals as their parts. |
| right_closed | A single logical value representing whether to treat right ends of intervals as their parts. |
| f | A pdqr-function. |
| region2 | A data frame representing region. |
| method | Method for computing distance between regions in
|
| col | Single color of rectangles to be used. Should be appropriate for
|
| alpha | Single number representing factor modifying the opacity alpha; typically in [0; 1]. |
region_is_in()
returns a logical vector (with length equal to
length of x
) representing whether certain element of x
is inside a
region.
region_prob()
returns a single number between 0 and 1 representing total
probability of region.
region_height()
returns a single number representing a height of a region
with respect to f
, i.e. minimum value that corresponding d-function can
return based on relevant points inside a region.
region_width()
returns a single number representing total width of a
region.
region_draw()
draws colored rectangles filling region
intervals.
region_is_in()
tests each value of x
for being inside interval.
In other words, if there is a row for which element of x
is between "left"
and "right" value (respecting left_closed
and right_closed
options),
output for that element will be TRUE
. Note that for zero-width
intervals one of left_closed
or right_closed
being TRUE
is enough to
accept that point as "in region".
region_prob()
computes total probability of region according to
pdqr-function f
. If f
has "discrete" type, output is
computed as sum of probabilities for all "x" values from "x_tbl" metadata which lie inside a region (respecting left_closed
and right_closed
options while using region_is_in()
). If f
has
"continuous" type, output is computed as integral of density over a region
(*_closed
options having any effect).
region_height()
computes "height" of a region (with respect to f
):
minimum value of corresponding to f
d-function can return based on relevant
points inside a region. If f
has "discrete" type, those relevant points are
computed as "x" values from "x_tbl" metadata which lie inside a region (if
there are no such points, output is 0). If f
has "continuous" type, the
whole intervals are used as relevant points. The notion of "height" comes
from summ_hdr()
function: if region
is summ_hdr(f, level)
for some
level
, then region_height(region, f)
is what is called in summ_hdr()
's
docs as "target height" of HDR. That is, a maximum value of d-function for
which a set consisting from points at which d-function has values not less
than target height and total probability of the set being not less than
level
.
region_width()
computes total width of a region, i.e. sum of differences
between "right" and "left" columns.
region_distance()
computes distance between a pair of regions. As in
summ_distance()
, it is a single non-negative number representing how much
two regions differ from one another (bigger values indicate bigger
difference). Argument method
represents method of computing distance.
Method "Jaccard" computes Jaccard distance: one minus ratio of intersection
width and union width. Other methods come from summ_distance()

represent distance between regions as probability distributions:
If total width of region is zero (i.e. it consists only from points), distribution is a uniform discrete one based on points from region.
If total width is positive, then distribution is a uniform continuous one based on intervals with positive width.

Vector driver implementation tutorial
Overall Approach
In general new formats are added to OGR by implementing format
specific drivers with instantiating a GDALDriver
and subclasses of
GDALDataset
and OGRLayer
. The GDALDriver instance is registered with
the GDALDriverManager
at runtime.
Before following this tutorial to implement an OGR driver, please review the Vector Data Model document carefully.
The tutorial will be based on implementing a simple ascii point format.
Implementing GDALDriver
The format specific driver class is implemented as a instance of GDALDriver. One instance of the driver will normally be created, and registered with the GDALDriverManager. The instantiation of the driver is normally handled by a global C callable registration function, similar to the following placed in the same file as the driver class.
void RegisterOGRSPF()
{
if( GDALGetDriverByName("SPF") != NULL )
return;
GDALDriver *poDriver = new GDALDriver();
poDriver->SetDescription("SPF");
poDriver->SetMetadataItem(GDAL_DCAP_VECTOR, "YES");
poDriver->SetMetadataItem(GDAL_DMD_LONGNAME, "Long name for SPF driver");
poDriver->SetMetadataItem(GDAL_DMD_EXTENSION, "spf");
poDriver->SetMetadataItem(GDAL_DMD_HELPTOPIC, "drv_spf.html");
poDriver->pfnOpen = OGRSPFDriverOpen;
poDriver->pfnIdentify = OGRSPFDriverIdentify;
poDriver->pfnCreate = OGRSPFDriverCreate;
poDriver->SetMetadataItem(GDAL_DCAP_VIRTUALIO, "YES");
GetGDALDriverManager()->RegisterDriver(poDriver);
}
The GDALDriver::SetDescription()
sets the name of the driver. This name is specified
on the commandline when creating datasources so it is generally good to keep
it short and without any special characters or spaces.
SetMetadataItem( GDAL_DCAP_VECTOR, "YES" ) is specified to indicate that the driver will handle vector data.
SetMetadataItem( GDAL_DCAP_VIRTUALIO, "YES" ) is specified to indicate that the driver can deal with files opened with the VSI*L GDAL API. Otherwise this metadata item should not be defined.
The driver declaration generally looks something like this for a format with read or read and update access (the Open() method) and creation support (the Create() method).
static GDALDataset* OGRSPFDriverOpen(GDALOpenInfo* poOpenInfo);
static int OGRSPFDriverIdentify(GDALOpenInfo* poOpenInfo);
static GDALDataset* OGRSPFDriverCreate(const char* pszName, int nXSize, int nYSize,
int nBands, GDALDataType eDT, char** papszOptions);
The Open() method is called by GDALOpenEx()
. It should quietly return NULL if
the passed filename is not of the format supported by the driver. If it is the
target format, then a new GDALDataset object for the dataset should be returned.
It is common for the Open() method to be delegated to an Open() method on the actual format's GDALDataset class.
static GDALDataset *OGRSPFDriverOpen( GDALOpenInfo* poOpenInfo )
{
if( !OGRSPFDriverIdentify(poOpenInfo) )
return NULL;
OGRSPFDataSource *poDS = new OGRSPFDataSource();
if( !poDS->Open(poOpenInfo->pszFilename, poOpenInfo->eAccess == GA_Update) )
{
delete poDS;
return NULL;
}
return poDS;
}
The Identify() method is implemented as such :
static int OGRSPFDriverIdentify( GDALOpenInfo* poOpenInfo )
{
// Does this appear to be an .spf file?
return EQUAL(CPLGetExtension(poOpenInfo->pszFilename), "spf");
}
Examples of the Create() method is left for the section on creation and update.
Basic Read Only Data Source
We will start implementing a minimal read-only datasource. No attempt is made to optimize operations, and default implementations of many methods inherited from GDALDataset are used.
The primary responsibility of the datasource is to manage the list of layers. In the case of the SPF format a datasource is a single file representing one layer so there is at most one layer. The "name" of a datasource should generally be the name passed to the Open() method.
The Open() method below is not overriding a base class method, but we have it to implement the open operation delegated by the driver class.
For this simple case we provide a stub GDALDataset::TestCapability()
that returns FALSE
for all extended capabilities. The TestCapability() method is pure virtual,
so it does need to be implemented.
class OGRSPFDataSource : public GDALDataset
{
OGRSPFLayer **papoLayers;
int nLayers;
public:
OGRSPFDataSource();
~OGRSPFDataSource();
int Open( const char *pszFilename, int bUpdate );
int GetLayerCount() { return nLayers; }
OGRLayer *GetLayer( int );
int TestCapability( const char * ) { return FALSE; }
};
The constructor is a simple initializer to a default state. The Open() will take care of actually attaching it to a file. The destructor is responsible for orderly cleanup of layers.
OGRSPFDataSource::OGRSPFDataSource()
{
papoLayers = NULL;
nLayers = 0;
}
OGRSPFDataSource::~OGRSPFDataSource()
{
for( int i = 0; i < nLayers; i++ )
delete papoLayers[i];
CPLFree(papoLayers);
}
The Open() method is the most important one on the datasource, though in this particular instance it passes most of its work off to the OGRSPFLayer constructor if it believes the file is of the desired format.
Note that Open() methods should try and determine that a file isn't of the identified format as efficiently as possible, since many drivers may be invoked with files of the wrong format before the correct driver is reached. In this particular Open() we just test the file extension but this is generally a poor way of identifying a file format. If available, checking "magic header values" or something similar is preferable.
In the case of the SPF format, update in place is not supported, so we always fail if bUpdate is FALSE.
int OGRSPFDataSource::Open( const char *pszFilename, int bUpdate )
{
if( bUpdate )
{
CPLError(CE_Failure, CPLE_OpenFailed,
"Update access not supported by the SPF driver.");
return FALSE;
}
// Create a corresponding layer.
nLayers = 1;
papoLayers = static_cast<OGRSPFLayer **>(CPLMalloc(sizeof(void *)));
papoLayers[0] = new OGRSPFLayer(pszFilename);
pszName = CPLStrdup(pszFilename);
return TRUE;
}
A GetLayer() method also needs to be implemented. Since the layer list is created in the Open() this is just a lookup with some safety testing.
OGRLayer *OGRSPFDataSource::GetLayer( int iLayer )
{
if( iLayer < 0 || iLayer >= nLayers )
return NULL;
return papoLayers[iLayer];
}
Read Only Layer
The OGRSPFLayer is implements layer semantics for an .spf file. It provides access to a set of feature objects in a consistent coordinate system with a particular set of attribute columns. Our class definition looks like this:
class OGRSPFLayer : public OGRLayer
{
OGRFeatureDefn *poFeatureDefn;
FILE *fp;
int nNextFID;
public:
OGRSPFLayer( const char *pszFilename );
~OGRSPFLayer();
void ResetReading();
OGRFeature * GetNextFeature();
OGRFeatureDefn * GetLayerDefn() { return poFeatureDefn; }
int TestCapability( const char * ) { return FALSE; }
};
The layer constructor is responsible for initialization. The most important
initialization is setting up the OGRFeatureDefn
for the layer. This defines
the list of fields and their types, the geometry type and the coordinate
system for the layer. In the SPF format the set of fields is fixed - a
single string field and we have no coordinate system info to set.
Pay particular attention to the reference counting of the OGRFeatureDefn. As OGRFeature's for this layer will also take a reference to this definition, it is important that we also establish a reference on behalf of the layer itself.
OGRSPFLayer::OGRSPFLayer( const char *pszFilename )
{
nNextFID = 0;
poFeatureDefn = new OGRFeatureDefn(CPLGetBasename(pszFilename));
SetDescription(poFeatureDefn->GetName());
poFeatureDefn->Reference();
poFeatureDefn->SetGeomType(wkbPoint);
OGRFieldDefn oFieldTemplate("Name", OFTString);
poFeatureDefn->AddFieldDefn(&oFieldTemplate);
fp = VSIFOpenL(pszFilename, "r");
if( fp == NULL )
return;
}
Note that the destructor uses OGRFeatureDefn::Release()
on the OGRFeatureDefn. This will
destroy the feature definition if the reference count drops to zero, but if
the application is still holding onto a feature from this layer, then that
feature will hold a reference to the feature definition and it will not
be destroyed here (which is good!).
OGRSPFLayer::~OGRSPFLayer()
{
poFeatureDefn->Release();
if( fp != NULL )
VSIFCloseL(fp);
}
The OGRLayer::GetNextFeature()
method is usually the work horse of OGRLayer
implementations. It is responsible for reading the next feature according
to the current spatial and attribute filters installed.
The while() loop is present to loop until we find a satisfactory feature. The first section of code is for parsing a single line of the SPF text file and establishing the x, y and name for the line.
OGRFeature *OGRSPFLayer::GetNextFeature()
{
// Loop till we find a feature matching our requirements.
while( true )
{
const char *pszLine = CPLReadLineL(fp);
// Are we at end of file (out of features)?
if( pszLine == NULL )
return NULL;
const double dfX = atof(pszLine);
pszLine = strstr(pszLine,"|");
if( pszLine == NULL )
continue; // we should issue an error!
else
pszLine++;
const double dfY = atof(pszLine);
pszLine = strstr(pszLine,"|");
const char *pszName = NULL;
if( pszLine == NULL )
continue; // we should issue an error!
else
pszName = pszLine + 1;
The next section turns the x, y and name into a feature. Also note that we assign a linearly incremented feature id. In our case we started at zero for the first feature, though some drivers start at 1.
OGRFeature *poFeature = new OGRFeature(poFeatureDefn);
poFeature->SetGeometryDirectly(new OGRPoint(dfX, dfY));
poFeature->SetField(0, pszName);
poFeature->SetFID(nNextFID++);
Next we check if the feature matches our current attribute or
spatial filter if we have them. Methods on the OGRLayer base class
support maintain filters in the OGRLayer member fields OGRLayer::m_poFilterGeom
(spatial filter) and OGRLayer::m_poAttrQuery
(attribute filter) so we can just use
these values here if they are non-NULL. The following test is essentially
"stock" and done the same in all formats. Some formats also do some
spatial filtering ahead of time using a spatial index.
If the feature meets our criteria we return it. Otherwise we destroy it, and return to the top of the loop to fetch another to try.
if( (m_poFilterGeom == NULL ||
FilterGeometry(poFeature->GetGeometryRef())) &&
(m_poAttrQuery == NULL ||
m_poAttrQuery->Evaluate(poFeature)) )
return poFeature;
delete poFeature;
}
}
While in the middle of reading a feature set from a layer, or at any other
time the application can call OGRLayer::ResetReading()
which is intended to restart
reading at the beginning of the feature set. We implement this by seeking
back to the beginning of the file, and resetting our feature id counter.
void OGRSPFLayer::ResetReading()
{
VSIFSeekL(fp, 0, SEEK_SET);
nNextFID = 0;
}
In this implementation we do not provide a custom implementation for the GetFeature() method. This means an attempt to read a particular feature by its feature id will result in many calls to GetNextFeature() until the desired feature is found. However, in a sequential text format like spf there is little else we could do anyway.
There! We have completed a simple read-only feature file format driver.
