Get the reference to the current class from which this object was instantiated. Unlike statics,\nthis.self is scope-dependent and it's meant to be used for dynamic inheritance. See statics\nfor a detailed comparison

Call the original method that was previously overridden with override

\n\n

Ext.define('My.Cat', {\n    constructor: function() {\n        alert(\"I'm a cat!\");\n    }\n});\n\nMy.Cat.override({\n    constructor: function() {\n        alert(\"I'm going to be a cat!\");\n\n        this.callOverridden();\n\n        alert(\"Meeeeoooowwww\");\n    }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n                          // alerts \"I'm a cat!\"\n                          // alerts \"Meeeeoooowwww\"\n

This method has been deprecated

as of 4.1. Use callParent instead.

\n\n

Parameters

args : Array/Arguments
The arguments, either an array or the arguments object\nfrom the current method, for example: this.callOverridden(arguments)
\n

Returns

Object
Returns the result of calling the overridden method

callParent( args ) : Objectprotected

Call the \"parent\" method of the current method. ...

Call the \"parent\" method of the current method. That is the method previously\noverridden by derivation or by an override (see Ext.define).

\n\n

 Ext.define('My.Base', {\n     constructor: function (x) {\n         this.x = x;\n     },\n\n     statics: {\n         method: function (x) {\n             return x;\n         }\n     }\n });\n\n Ext.define('My.Derived', {\n     extend: 'My.Base',\n\n     constructor: function () {\n         this.callParent([21]);\n     }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x);  // alerts 21\n

\n\n

This can be used with an override as follows:

\n\n

 Ext.define('My.DerivedOverride', {\n     override: 'My.Derived',\n\n     constructor: function (x) {\n         this.callParent([x*2]); // calls original My.Derived constructor\n     }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x);  // now alerts 42\n

\n\n

This also works with static methods.

\n\n

 Ext.define('My.Derived2', {\n     extend: 'My.Base',\n\n     statics: {\n         method: function (x) {\n             return this.callParent([x*2]); // calls My.Base.method\n         }\n     }\n });\n\n alert(My.Base.method(10);     // alerts 10\n alert(My.Derived2.method(10); // alerts 20\n

\n\n

Lastly, it also works with overridden static methods.

\n\n

 Ext.define('My.Derived2Override', {\n     override: 'My.Derived2',\n\n     statics: {\n         method: function (x) {\n             return this.callParent([x*2]); // calls My.Derived2.method\n         }\n     }\n });\n\n alert(My.Derived2.method(10); // now alerts 40\n

\n\n

To override a method and replace it and also call the superclass method, use\ncallSuper. This is often done to patch a method to fix a bug.

Parameters

args : Array/Arguments
The arguments, either an array or the arguments object\nfrom the current method, for example: this.callParent(arguments)
\n

Returns

Object
Returns the result of calling the parent method
\n

callSuper( args ) : Objectprotected

This method is used by an override to call the superclass method but bypass any\noverridden method. ...

This method is used by an override to call the superclass method but bypass any\noverridden method. This is often done to \"patch\" a method that contains a bug\nbut for whatever reason cannot be fixed directly.

\n\n

Consider:

\n\n

 Ext.define('Ext.some.Class', {\n     method: function () {\n         console.log('Good');\n     }\n });\n\n Ext.define('Ext.some.DerivedClass', {\n     method: function () {\n         console.log('Bad');\n\n         // ... logic but with a bug ...\n\n         this.callParent();\n     }\n });\n

\n\n

To patch the bug in DerivedClass.method, the typical solution is to create an\noverride:

\n\n

 Ext.define('App.paches.DerivedClass', {\n     override: 'Ext.some.DerivedClass',\n\n     method: function () {\n         console.log('Fixed');\n\n         // ... logic but with bug fixed ...\n\n         this.callSuper();\n     }\n });\n

\n\n

The patch method cannot use callParent to call the superclass method since\nthat would call the overridden method containing the bug. In other words, the\nabove patch would only produce \"Fixed\" then \"Good\" in the console log, whereas,\nusing callParent would produce \"Fixed\" then \"Bad\" then \"Good\".

Parameters

args : Array/Arguments
The arguments, either an array or the arguments object\nfrom the current method, for example: this.callSuper(arguments)
\n

Returns

Object
Returns the result of calling the superclass method

dispatch( target, ev, args ) : Booleanprivate

This method dispatches an event fired by an object monitored by this domain. ...

This method dispatches an event fired by an object monitored by this domain. This\nis not called directly but is called by interceptors injected by the monitor method.

Parameters

target : Object
The firer of the event.
\n
ev : String
The event being fired.
\n
args : Array
The arguments for the event. This array does not include the event name.\nThat has already been sliced off because this class intercepts the fireEventArgs\nmethod which takes an array as the event's argument list.
\n

Returns

Boolean
false if any listener returned false, otherwise true.

listen( listeners )private

This method adds listeners on behalf of a controller. ...

This method adds listeners on behalf of a controller. Since Global domain does not\nsupport selectors, we skip this layer and just accept an object keyed by events.\nFor example:

\n\n

 domain.listen({\n     idle: function() { ... },\n     afterlayout: {\n         fn: function() { ... },\n         delay: 10\n     }\n });\n

Parameters

listeners : Object
Config object containing listeners.
\n

Overrides: Ext.app.EventDomain.listen

match( target, selector ) : Booleanprotected

This method matches the firer of the event (the target) to the given selector. ...

This method matches the firer of the event (the target) to the given selector.\nDefault matching is very simple: a match is true when selector equals target's\nidProperty, or when selector is '*' wildcard to match any\ntarget.

Parameters

target : Object
The firer of the event.
\n\n
selector : String
The selector to which to match the target.
\n\n

Returns

Boolean
true if the target matches the selector.
\n\n

Overrides: Ext.app.EventDomain.match

monitor( observable )protected

This method is called by the derived class to monitor fireEvent calls. ...

This method is called by the derived class to monitor fireEvent calls. Any call\nto fireEvent on the target Observable will be intercepted and dispatched to any\nlistening Controllers. Assuming the original fireEvent method does not return\nfalse, the event is passed to the dispatch method of this object.

\n\n

This is typically called in the constructor of derived classes.

Parameters

observable : Ext.Class
The Observable to monitor for events.

statics( ) : Ext.Classprotected

Get the reference to the class from which this object was instantiated. ...

Get the reference to the class from which this object was instantiated. Note that unlike self,\nthis.statics() is scope-independent and it always returns the class from which it was called, regardless of what\nthis points to during run-time

\n\n

override( members ) : Ext.Basechainabledeprecatedstatic

Override members of this class. ...

Override members of this class. Overridden methods can be invoked via\ncallParent.

\n\n

Ext.define('My.Cat', {\n    constructor: function() {\n        alert(\"I'm a cat!\");\n    }\n});\n\nMy.Cat.override({\n    constructor: function() {\n        alert(\"I'm going to be a cat!\");\n\n        this.callParent(arguments);\n\n        alert(\"Meeeeoooowwww\");\n    }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n                          // alerts \"I'm a cat!\"\n                          // alerts \"Meeeeoooowwww\"\n

\n\n

As of 4.1, direct use of this method is deprecated. Use Ext.define\ninstead:

\n\n

Ext.define('My.CatOverride', {\n    override: 'My.Cat',\n    constructor: function() {\n        alert(\"I'm going to be a cat!\");\n\n        this.callParent(arguments);\n\n        alert(\"Meeeeoooowwww\");\n    }\n});\n

\n\n

The above accomplishes the same result but can be managed by the Ext.Loader\nwhich can properly order the override and its target class and the build process\ncan determine whether the override is needed based on the required state of the\ntarget class (My.Cat).

This method has been deprecated since 4.1.0

Use Ext.define instead

\n\n
