Ext.ClassManager manages all classes and handles mapping from string class name to actual class objects throughout the whole framework. It is not generally accessed directly, rather through these convenient shorthands:

Defined By

Methods

 
create( String className, Object data, Function createdFn) : Ext.Base
Defines a class. This is usually invoked via the alias Ext.define Ext.ClassManager.create('My.awesome.Class', { ...

Defines a class. This is usually invoked via the alias Ext.define

Ext.ClassManager.create('My.awesome.Class', {
    someProperty: 'something',
    someMethod: function() { ... }
    ...

}, function() {
    alert('Created!');
    alert(this === My.awesome.Class); // alerts true

    var myInstance = new this();
});

Parameters

  • className : String

    The class name to create in string dot-namespaced format, for example: 'My.very.awesome.Class', 'FeedViewer.plugin.CoolPager' It is highly recommended to follow this simple convention:

    • The root and the class name are 'CamelCased'
    • Everything else is lower-cased
  • data : Object

    The key - value pairs of properties to apply to this class. Property names can be of any valid strings, except those in the reserved listed below:

    • mixins
    • statics
    • config
    • alias
    • self
    • singleton
    • alternateClassName
  • createdFn : Function

    Optional callback to execute after the class is created, the execution scope of which (this) will be the newly created class itself.

Returns

  • Ext.Base   
 
get( String name) : Class

Retrieve a class by its name.

Retrieve a class by its name.

Parameters

  • name : String

Returns

  • Class

Parameters

Returns

  • Array   

    aliases

 

Get a reference to the class by its alias.

Parameters

  • alias : String

Returns

Get the class of the provided object; returns null if it's not an instance of any class created with Ext.define. This is usually invoked by the shorthand Ext.getClass

var component = new Ext.Component();

Ext.ClassManager.getClass(component); // returns Ext.Component

Parameters

  • object : Object

Returns

  • Class   

    class

 

 

Parameters

  • object : Mixed

Returns

  • void   
 
getName( Class/Object object) : String

Get the name of the class by its reference or its instance; usually invoked by the shorthand Ext.getClassName

Ext.ClassManager.getName(Ext.Action); // returns "Ext.Action"

Parameters

  • object : Class/Object

Returns

  • String   

    className

 

Get the name of a class by its alias.

Get the name of a class by its alias.

Parameters

  • alias : String

Returns

  • String   

    className

 

Get the name of a class by its alternate name.

Get the name of a class by its alternate name.

Parameters

  • alternate : String

Returns

  • String   

    className

Converts a string expression to an array of matching class names. An expression can either refers to class aliases or class names. Expressions support wildcards:

 // returns ['Ext.window.Window']
var window = Ext.ClassManager.getNamesByExpression('widget.window');

// returns ['widget.panel', 'widget.window', ...]
var allWidgets = Ext.ClassManager.getNamesByExpression('widget.*');

// returns ['Ext.data.Store', 'Ext.data.ArrayProxy', ...]
var allData = Ext.ClassManager.getNamesByExpression('Ext.data.*');

Parameters

  • expression : String

Returns

  • Array   

    classNames

 
instantiate( String name, Mixed args) : Object

Instantiate a class by either full name, alias or alternate name; usually invoked by the convenient shorthand Ext.create

If Ext.Loader is enabled and the class has not been defined yet, it will attempt to load the class via synchronous loading.

For example, all these three lines return the same result:

// alias
var window = Ext.ClassManager.instantiate('widget.window', { width: 600, height: 800, ... });

// alternate name
var window = Ext.ClassManager.instantiate('Ext.Window', { width: 600, height: 800, ... });

// full class name
var window = Ext.ClassManager.instantiate('Ext.window.Window', { width: 600, height: 800, ... });

Parameters

  • name : String
  • args : Mixed

    ,... Additional arguments after the name will be passed to the class' constructor.

Returns

  • Object   

    instance

var window = Ext.ClassManager.instantiateByAlias('widget.window', { width: 600, height: 800, ... });

Parameters

  • alias : String
  • args : Mixed

    ,... Additional arguments after the alias will be passed to the class constructor.

Returns
