WHAT IS DELEGATION?
===================
Delegation is a feature that lets you create "proxy" methods that do nothing more than call some other method on an attribute.
This is quite handy since it lets you simplify a complex set of "has-a" relationships and present a single unified API from one class.
With delegation, consumers of a class don't need to know about all the objects it contains, reducing the amount of API they need to learn.
Delegations are defined as a mapping between one or more methods provided by the "real" class (the delegatee), and a set of corresponding methods in the delegating class.
The delegating class can re-use the method names provided by the delegatee or provide its own names.
DEFINING A MAPPING
==================
In the simplest form mapping is a string, which corresponds to the proxy method name.
has : {
someAttr : 'method'
}
Its possible to specify an array with the method names:
has : {
someAttr : {
handles : [ 'method1', 'method2' ]
}
}
For each array entry, in the class consuming the attribute, will be created a proxy method. This method will delegate to the method of the attribute with the same name.
Its possible to rename methods during mapping, supplying the mapping value as object:
has : {
someAttr : {
handles : {
proxyMethod : 'methodOfTheAttribute'
}
}
}

JooseX.Attribute.Trigger - call a function after attribute has been changed via setter call
SYNOPSIS
========
Class('Some.Class', {

trigger : function (newValue) {

DESCRIPTION
===========
`JooseX.Attribute.Trigger` is a role, which triggers a function call, after an attribute was changed via setter call.
It is called as a method (in the scope of the instance), and receives the new value as argument.
Trigger is also called when an attribute's value is passed to the constructor.
**Note**, that trigger will not be called for the value of attribute's `init` option, as it only translates the value to the prototype of the class

JooseX.Attribute.Lazy - a role, deferring the attribute initialization untill first call to getter
SYNOPSIS
========
Class('Some.Class', {

lazyAttribute : {

return this.someCostlyComputation()

lazy : true

instance.lazyAttribute == undefined // true, initializer of lazy attribute wasn't called yet
var lazy = instance.getLazyAttibute()
instance.lazyAttribute != undefined // true, initializer of lazy attribute was called
DESCRIPTION
===========
Joose lets you defer attribute population by making an attribute lazy (see the [Synopsis][] for syntax)
When `lazy` flag is set, the default is not generated until the getter method is called, rather than at object construction time.
There are several reasons you might choose to do this.
First, if the default value for this attribute depends on some other attributes, then the attribute must be lazy.
During object construction, defaults are not generated in a predictable order, so you cannot count on some other attribute being populated when generating a default.
Second, there's often no reason to calculate a default before it's needed. Making an attribute lazy lets you defer the cost until the attribute is needed.
If the attribute is never needed, you save some CPU time.

JooseX.Attribute.Accessor.Combined - a role, combining setter and getter methods into one, ala perl
SYNOPSIS
========
Class('Some.Class', {
has : {
attr : {
is : 'rwc',
init : 'some init value'
}
}
})
var instance = new Some.Class()
instance.attr() == 'some init value' // call to combined accessor as getter
instance.attr('some other value') // call to combined accessor as setter
instance.attr() == 'some other value' // attribute was changed
DESCRIPTION
===========
This role combines the getter and setter methods into one, having the same name as attribute itself.
Call this method without arguments will be directed to the actual getter call.
Call with some arguments provided will be directed to setter call.
Its safe to combine this role with Lazy and Trigger, but it should be applied after them.
USAGE
=====
To enable this role provide the trailing `c` character in attribute's `is` option:
has : {
attr : {
is : 'rwc',
init : 'some init value'
}
}
Alternatively, explicitly specify `isCombined` option with some `true` value:
has : {
attr : {
is : 'rw',
isCombined : true,
init : 'some init value'
}
}

JooseX.Namespace.Depended.Manager - A global collection of all resources
SYNOPSIS
========
JooseX.Namespace.Depended.Manager.my.registerResourceClass('custom-type', JooseX.Namespace.Depended.Resource.Custom)
DESCRIPTION
===========
`JooseX.Namespace.Depended.Manager` is a global collection of all resources.
**Note:** Its a pure [static](/go/index_l_Joose.Manual.Static.html) class - all its methods and properties are static.
METHODS
=======
### registerResourceClass
> `void registerResourceClass(String type, Class constructor)`
> After you've created your custom resource class, you need to register it with call to this method.
> Then you can refer to new resources with the following descriptors:
{
type : 'custom-type',
token : 'some-token'
}
GETTING HELP
============
This extension is supported via github issues tracker: <http://github.com/SamuraiJack/JooseX-Namespace-Depended-Manager/issues>

JooseX.Namespace.Depended.Resource - Abstract resource class
SYNOPSIS
========
//mostly for subclassing only
Class("JooseX.Namespace.Depended.Resource.JavaScript", {
isa : JooseX.Namespace.Depended.Resource,
...
})
DESCRIPTION
===========
`JooseX.Namespace.Depended.Resource` is an abstract resource class. Its not supposed to be used directly, instead you should use
one of its subclasses.
ATTRIBUTES
==========
### attachedTo
> `Object attachedTo`
> An arbitrary object to which this resource is attached (its a corresponding class in JooseX.Namespace.Depended)
### type
> `String type`
> A type of resource - plain string. `JooseX.Namespace.Depended.Manager` maintain a collection of resource types, accessible
### token
> `String token`
> A token of resource - plain string with arbitrary semantic. Each subclass should provide this semantic along with `token -> url` conertion method (locator)
### id
> `String id`
> An id of resource - is computed as `type + '/doc/s/sa/samuraijack/KiokuJS/001/lib/Task/KiokuJS//index.html' + token'
### loading
> `Boolean loading`
> A sign whether this resource is currently loading
### loaded
> `Boolean loaded`
> A sign whether this resource is already loaded
### ready
> `Boolean ready`
> A sign whether this resource is considered ready. Resource is ready, when its loaded, and all its dependencies are ready.
### loadedFromURL
> `String loadedFromURL`
> An url, from which the resource was loaded.
### readyListeners
> `Array[Function] readyListeners`
> An array of functions, which will be called after this resource becomes ready. Functions will be called sequentially.
### dependencies
> `Object dependencies`
> An object containing the dependencies of this resource. Keys are the `id`s of resources and the values - the resource instances itself.
### onBeforeReady
> `Function onBeforeReady`
> A function, which will be called, right after the all dependencies of the resource became ready, but before its own `readyListeners` will be called.
It supposed to perform any needed additional actions to post-process the loaded resource.
> Function will receive two arguments - the 1st is the callback, which should be called when `onBeforeReady` will finish its work. 2nd is the resource instance.
### version
> `r/w Number version`
> A version of this resource. Currently is handled as Number, this may change in future releases.
### requiredVersion
> `r/w Number requiredVersion`
> A *requiredVersion* version of this resource. Required here means the maximum version from all references to this resource.
METHODS
=======
### addDescriptor
> `void addDescriptor(Object|String descriptor)`
> Add the resource, described with passed descriptor as the dependency for this resource.
### getUrls
> `String|Array[String] getUrls()`
> Abstract method, will throw an exception if not overriden. It should return the array of urls (or a single url) from which this resource can be potentially loaded.
This method should take into account the `JooseX.Namespace.Depended.Manager.my.INC` setting
### load
> `void load(String url, Function onsuccess, Function onerror)`
> Abstract method, will throw an exception if not overriden. It should load the content of the resource from the passed `url`. If there was an error during loading
(for example file not found) should not throw the exception. Instead, should call the `onerror` continuation with it (exception instance).
> After successfull loading, should call the `onsuccess` continuation with the resource content as 1st argument, and `url` as 2nd: `onsuccess(text, url)`
### materialize
> `void materialize(String resourceBlob, String url)`
> Abstract method, will throw an exception if not overriden. It should "materialize" the resource. The concrete semantic of this action is determined by resource nature.
For example this method can create some tag in the DOM tree, or execute the code or something else.
> Currently this method is supposed to operate synchronously, this may change in future releases.

Name
====
JooseX.CPS.Continuation - A continuation class
SYNOPSIS
========
TRY = function () {
var continuation = new JooseX.CPS.Continuation()
return continuation.TRY.apply(continuation, arguments)
}
DESCRIPTION
===========
`JooseX.CPS.Continuation` implements a continuation - an underlaying basis for `JooseX.CPS` trait.
ISA
===
None.
DOES
====
None.
TRAITS
======
None.
ATTRIBUTES
==========
### parent
> `JooseX.CPS.Continuation parent`
> A parent for this continuation. Can be asked for default scope or for the [nextFunc]
### previous
> `JooseX.CPS.Continuation previous`
> A previous continuation for this continuation. Can be asked for default scope or for the [nextFunc]
### statements
> `Array statements`
> An array of statements. Each statement is an object like :
{
func : ... , // function to execute
scope : ... , // scope into which execute the function
args : ... // arguments for function
}
### type
> `String type`
> The type of this continuation. Can be 'Sequential' or 'Parallel's
### entered
> `Boolean entered`
> The sign whether this continuation was already entered - i.e. activated.
### leaved
> `Boolean leaved`
> The sign whether this continuation was already leaved - i.e. the `CONTINUE` or `THROW` method were called.
### defaultScope
> `Object defaultScope`
> The default scope which will be supplied to the statements if not provided explicitly. Once passed to `TRY`, propagates to the further statements.
### nextFunc
> `Function nextFunc`
> If present, this function will be called, when leaving this continuation. Will be called in the global scope, with the arguments from the method, initated the leave.
### catchFunc/finallyFunc
> `Function catchFunc/finallyFunc`
> The functions for `CATCH/FINALLY` statements accordingly.
### catchScope/finallyScope
> `Object catchScope/finallyScope`
> The scopes for `CATCH/FINALLY` statements accordingly.
METHODS
=======
### TRY
> `JooseX.CPS.Continuation TRY(Function func, Object scope?, Array args?)`
> Add a statement to the current continuation. If continuation already contains `CATCH` or `FINALLY` statements - then delegate to `NEXT` and return a next continuation instance.
otherwise return current continuation.
### THEN
> `JooseX.CPS.Continuation THEN(Function func, Object scope?, Array args?)`
> Alias for `TRY` with a single exception. If the type of the continuation is `Parallel` then delegate to `NEXT` and return a next continuation instance.
> Has a lower-case synonym : 'then'
### CATCH
> `JooseX.CPS.Continuation CATCH(Function func, Object scope?)`
> Add a `CATCH` statement to the current continuation.
> Has a lower-case synonym : 'except'
### FINALLY
> `JooseX.CPS.Continuation FINALLY(Function func, Object scope?)`
> Add a `FINALLY` statement to the current continuation.
> Has a lower-case synonym : 'ensure'
### NEXT
> `JooseX.CPS.Continuation NEXT(Function func, Object scope?, Array args?)`
> Derive a sibling continuation, chaining it after itself. Return newly created continuation.
> Has a lower-case synonym : 'next'
### AND
> `JooseX.CPS.Continuation AND(Function func, Object scope?, Array args?)`
> Alias for `TRY` that also switch a type of the continuation to `Parallel`.
> Has a lower-case synonym : 'and'
### NOW
> `JooseX.CPS.Continuation NOW()`
> Activates current continuation graph by looking the 1st not yet entered continuation. After finding it, delegate to its `entry` method with the passed arguments.
> Has a lower-case synonym : 'now'
### getCONTINUE
> `Function getCONTINUE()`
> Return a function, binded to the `CONTINUE` method of itself.
### getRETURN
> `Function getRETURN()`
> Return a function, binded to the `RETURN` method of itself.
### getTHROW
> `Function getTHROW()`
> Return a function, binded to the `THROW` method of itself.

This file creates a global JSON object containing two methods: stringify
and parse.
JSON.stringify(value, replacer, space)
value any JavaScript value, usually an object or array.
replacer an optional parameter that determines how object
values are stringified for objects. It can be a
function or an array of strings.
space an optional parameter that specifies the indentation
of nested structures. If it is omitted, the text will
be packed without extra whitespace. If it is a number,
it will specify the number of spaces to indent at each
level. If it is a string (such as '\t' or ' '),
it contains the characters used to indent at each level.
This method produces a JSON text from a JavaScript value.
When an object value is found, if the object contains a toJSON
method, its toJSON method will be called and the result will be
stringified. A toJSON method does not serialize: it returns the
value represented by the name/value pair that should be serialized,
or undefined if nothing should be serialized. The toJSON method
will be passed the key associated with the value, and this will be
bound to the value
For example, this would serialize Dates as ISO strings.
Date.prototype.toJSON = function (key) {
function f(n) {
// Format integers to have at least two digits.
return n < 10 ? '0' + n : n;
}
return this.getUTCFullYear() + '-' +
f(this.getUTCMonth() + 1) + '-' +
f(this.getUTCDate()) + 'T' +
f(this.getUTCHours()) + ':' +
f(this.getUTCMinutes()) + ':' +
f(this.getUTCSeconds()) + 'Z';
};
You can provide an optional replacer method. It will be passed the
key and value of each member, with this bound to the containing
object. The value that is returned from your method will be
serialized. If your method returns undefined, then the member will
be excluded from the serialization.
If the replacer parameter is an array of strings, then it will be
used to select the members to be serialized. It filters the results
such that only members with keys listed in the replacer array are
stringified.
Values that do not have JSON representations, such as undefined or
functions, will not be serialized. Such values in objects will be
dropped; in arrays they will be replaced with null. You can use
a replacer function to replace those with JSON values.
JSON.stringify(undefined) returns undefined.
The optional space parameter produces a stringification of the
value that is filled with line breaks and indentation to make it
easier to read.
If the space parameter is a non-empty string, then that string will
be used for indentation. If the space parameter is a number, then
the indentation will be that many spaces.
Example:
text = JSON.stringify(['e', {pluribus: 'unum'}]);
// text is '["e",{"pluribus":"unum"}]'
text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
// text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
text = JSON.stringify([new Date()], function (key, value) {
return this[key] instanceof Date ?
'Date(' + this[key] + ')' : value;
});
// text is '["Date(---current time---)"]'
JSON.parse(text, reviver)
This method parses a JSON text to produce an object or array.
It can throw a SyntaxError exception.
The optional reviver parameter is a function that can filter and
transform the results. It receives each of the keys and values,
and its return value is used instead of the original value.
If it returns what it received, then the structure is not modified.
If it returns undefined then the member is deleted.
Example:
// Parse the text. Values that look like ISO date strings will
// be converted to Date objects.
myData = JSON.parse(text, function (key, value) {
var a;
if (typeof value === 'string') {
a =
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
if (a) {
return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+a[5], +a[6]));
}
}
return value;
});
myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
var d;
if (typeof value === 'string' &&
value.slice(0, 5) === 'Date(' &&
value.slice(-1) === ')') {
d = new Date(value.slice(5, -1));
if (d) {
return d;
}
}
return value;
});
