\nGet 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
Ext.define('My.Cat', {\n statics: {\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n alert(this.self.speciesName); / dependent on 'this'\n\n return this;\n },\n\n clone: function() {\n return new this.self();\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat'\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\nCall the original method that was previously overridden with override
\n\nExt.define('My.Cat', {\n constructor: function() {\n alert(\"I'm a cat!\");\n\n return this;\n }\n});\n\nMy.Cat.override({\n constructor: function() {\n alert(\"I'm going to be a cat!\");\n\n var instance = this.callOverridden();\n\n alert(\"Meeeeoooowwww\");\n\n return instance;\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\"\nThe arguments, either an array or the arguments object
Returns the result after calling the overridden method
\nCall the parent's overridden method. For example:
\n\nExt.define('My.own.A', {\n constructor: function(test) {\n alert(test);\n }\n});\n\nExt.define('My.own.B', {\n extend: 'My.own.A',\n\n constructor: function(test) {\n alert(test);\n\n this.callParent([test + 1]);\n }\n});\n\nExt.define('My.own.C', {\n extend: 'My.own.B',\n\n constructor: function() {\n alert(\"Going to call parent's overriden constructor...\");\n\n this.callParent(arguments);\n }\n});\n\nvar a = new My.own.A(1); // alerts '1'\nvar b = new My.own.B(1); // alerts '1', then alerts '2'\nvar c = new My.own.C(2); // alerts \"Going to call parent's overriden constructor...\"\n // alerts '2', then alerts '3'\nThe arguments, either an array or the arguments object\nfrom the current method, for example: this.callParent(arguments)
Returns the result from the superclass' method
\nInitialize configuration for this class. a typical example:
\n\nExt.define('My.awesome.Class', {\n // The default config\n config: {\n name: 'Awesome',\n isAwesome: true\n },\n\n constructor: function(config) {\n this.initConfig(config);\n\n return this;\n }\n});\n\nvar awesome = new My.awesome.Class({\n name: 'Super Awesome'\n});\n\nalert(awesome.getName()); // 'Super Awesome'\nmixins The mixin prototypes as key - value pairs
\nTests whether the passed Component matches the selector string.
\nThe Component to test
\nThe selector string to test against.
\nTrue if the Component matches the selector.
\nReturns an array of matched Components from within the passed root object.
\n\nThis method filters returned Components in a similar way to how CSS selector based DOM\nqueries work using a textual selector string.
\n\nSee class summary for details.
\nThe selector string to filter returned Components
\nThe Container within which to perform the query.\nIf omitted, all Components within the document are included in the search.
\n\nThis parameter may also be an array of Components to filter according to the selector.
\nThe matched Components.
\nGet 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
Ext.define('My.Cat', {\n statics: {\n totalCreated: 0,\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n var statics = this.statics();\n\n alert(statics.speciesName); // always equals to 'Cat' no matter what 'this' refers to\n // equivalent to: My.Cat.speciesName\n\n alert(this.self.speciesName); // dependent on 'this'\n\n statics.totalCreated++;\n\n return this;\n },\n\n clone: function() {\n var cloned = new this.self; // dependent on 'this'\n\n cloned.groupName = this.statics().speciesName; // equivalent to: My.Cat.speciesName\n\n return cloned;\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n },\n\n constructor: function() {\n this.callParent();\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat', then alerts 'Cat'\n\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Cat', then alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\nalert(clone.groupName); // alerts 'Cat'\n\nalert(My.Cat.totalCreated); // alerts 3\n
