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:
- - - -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();
-});
-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 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:
- -mixinsstaticsconfigaliasselfsingletonalternateClassNameOptional callback to execute after the class is created, the execution scope of which
-(this) will be the newly created class itself.
Retrieve a class by its name.
-Retrieve a class by its name.
-class
-Get the aliases of a class by the class name
-Get the aliases of a class by the class name
-aliases
-Get a reference to the class by its alias.
-Get a reference to the class by its alias.
-class
-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
-class
-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"
-className
-Get the name of a class by its alias.
-Get the name of a class by its alias.
-className
-Get the name of a class by its alternate name.
-Get the name of a class by its alternate name.
-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.*');
-classNames
-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, ... });
-,... Additional arguments after the name will be passed to the class' constructor.
-instance
-Instantiate a class by its alias; usually invoked by the convenient shorthand Ext.createByAlias -If Ext.Loader is enabled and the class has not been defined yet, it will -attempt to load the class via synchronous loading.
- -var window = Ext.ClassManager.instantiateByAlias('widget.window', { width: 600, height: 800, ... });
-,... Additional arguments after the alias will be passed to the -class constructor.
-instance
-Checks if a class has already been created.
-Checks if a class has already been created.
-exist
-Register a post-processor function.
-Register a post-processor function.
-Sets a name reference to a class.
-Sets a name reference to a class.
-this
-Register the alias for a class.
-Register the alias for a class.
-a reference to a class or a className
-Alias to use when referring to this class
-Insert this post-processor at a specific position in the stack, optionally relative to -any existing post-processor
-Insert this post-processor at a specific position in the stack, optionally relative to -any existing post-processor
-The post-processor name. Note that it needs to be registered with -registerPostprocessor before this
-The insertion position. Four possible values are: -'first', 'last', or: 'before', 'after' (relative to the name provided in the third argument)
-this
-Set the default post processors array stack which are applied to every class.
-Set the default post processors array stack which are applied to every class.
-name of a registered post processor or an array of registered names.
-this
-Creates a namespace and assign the value to the created object
Ext.ClassManager.setNamespace('MyCompany.pkg.Example', someObject);
-
-alert(MyCompany.pkg.Example === someObject); // alerts true
-
