/**

Name
====


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](http://openjsan.org/go?l=Joose.Manual.Static) 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>

For general Joose questions you can also visit #joose on irc.freenode.org or the forum at: [http://joose.it/forum](http://joose.it/forum)

JooseX.Namespace.Depended.Resource - Abstract resource class 


SYNOPSIS
========
        
        //mostly for subclassing only
        Class("JooseX.Namespace.Depended.Resource.JooseClass", {
        
            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 + '://' + 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)`

> 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.

DESCRIPTION
===========

`JooseX.Namespace.Depended` is a dependencies handling framework, tightly integrated with Joose3. 

It allows you to refer to other (not yet loaded) classes/roles in your class declaration. 

Framework is highly customizable, additional resources/transport/materialization modes can be easily added.
Please refer to [JooseX.Namespace.Depended.Authoring][authoring] for more information. 

By default, framework operates in asynchronous mode, using XHR requests for transport and `eval` for "materialization".
All edge cases like refering to already loaded class, double loading, etc are handled correctly. 

 

CURRENT DEVELOPMENT STATUS
==========================

This framework is considered stable and thoroughly tested (more than 300 unit tests, including stress-test). 
The use case for "pure" Joose classes will be supported without breaking changes. 

However, as its not settled down yet, the syntax for loading *non Joose* code may be changed any time, without prior notice.


USAGE
=====

Dependency descriptor
---------------------

All dependencies should be specified with the *dependency descriptors*. In the simplest case, the descriptor is just a plain string 
with the name of class:

        'MyApp.Widget.Header'
    
In more complex case, the descriptor is an object, which keys are classes names and values - their's versions:

        {
            'MyApp.Widget.Header'   : 0.03,
            'MyApp.Util.Helper'     : 0.01
        }
        
Such descriptors can contain several dependencies, though they are limited to Joose classes only.

In general case, the dependency descriptor is an object with the following structure:
        
        {
            type    : 'joose',
            token   : 'MyApp.Widget.Header',
            version : 0.03
        }
        
Such descriptor can contain exactly one dependency, with the resource of any type.


The rule
--------

General rule is - whereever in your class declaration you can refer to other class (for example in the `does` builder) - you can specify the
dependency descriptor instead. 

This means, that you can specify the dependencies in:

    - `meta` builder (!)
    - `isa` builder
    - `trait` builder
    - `does` builder
    
    
For example this declaration is perfectly valid:    
    
            Class('Some.Class', {
                meta : 'My.Meta',
                
                isa : 'Super.Class',
                
                does : {
                    'Some.Role'         : 0.01,
                    'Some.Other.Role'   : 0.02
                },
                
                trait : 'Some.Trait',
                
                ...
            })
    
Also in any other custom builder (some [authoring][] required) 

The framework will scan class declaration for dependencies, pre-load them, then substitute descriptors with actual classes and continue the declaration process.


`use` builder
-------------

Additionaly, you can provide an array of dependencies (or a single dependency) in the `use` builder:
            
            Class('Some.Class', {
                
                use : [ 'Some.Other.Class', 'Some.Other.Role' ],
                
                ...
            })


`use` from code
---------------

You can also load the dependencies from code:

            use([ 'Some.Class1', 'Some.Class2' ], function () {
                
                var a = new Some.Class1()
                var b = new Some.Class2()
            })


Class name -> file name conversion
----------------------------------

The class name you are refering to, will be converted to file name using this simple scheme:

        class name: MyClass
        file  name: MyClass.js
        
        class name: Some.Class
        file  name: Some/Class.js
        
        class name: Some.Other.Class
        file  name: Some/Other/Class.js
    
Generally each dot is replaced with directory separator, and the 'js' extension is appended to result
    

The libraries
-------------

The framework can look up the classes in several *libraries*, which are just the directories, containing the source files.

The current list of libraries is stored as an array in: `JooseX.Namespace.Depended.Manager.my.INC`. Default value is:

        JooseX.Namespace.Depended.Manager.my.INC = [ 'lib', '/jsan' ]

You can freely modify this value. For example, if you are running a test harness, as `t/index.html`, and would like to refer
to your files, which are in `lib/`, you'll need to add the `../lib` entry.

Framework will scan through the libraries list sequentially and attempt to load the class from every entry.
Class will be loaded from the first library, which contains the corresponded file. If there are no such file,
loading will continue to another entry.

For example, if we are loading class `Some.Class`, and we have the default setting for libraries, then first it will be tried to load with the following URL:
    
        lib/Some/Class.js
    
If there are no such file, the 2nd entry will be tried:
        
        /jsan/Some/Class.js

If there are no such file again, the exception will be thrown.


ATTRIBUTE HELPER
================

This package adds a new [attribute initializer](http://openjsan.org/go?l=Joose.Manual.Attributes): `Joose.I.FutureClass`

It can be used, when the default value of the attribute should be set to the constructor of some class, 
which may be not yet loaded on the declaration stage:


        Class('MyApp.Widget.Template', {
            
            use : 'MyApp.Util.Helper',
            
            has : {
                helperClass : Joose.I.FutureClass('MyApp.Util.Helper')
            }
        
        })



GROUPED LOADING MODE
====================

This framework can operate in special mode, in which it can load *any* class, with *any number* of dependencies (in-depth),
with **2** http requests.

For more information about this mode please refer to <http://www.extjs.com/forum/showthread.php?t=69161> 

This item is currently in TODO list.
