This is a static class containing the system-supplied data types\nwhich may be given to a Field.

\n\n

The properties in this class are used as type indicators in the\nField class, so to test whether a Field is\nof a certain type, compare the type\nproperty against properties of this class.

\n\n

Developers may add their own application-specific data types to\nthis class. Definition names must be UPPERCASE. Each type\ndefinition must contain three properties:

\n\n\n\n\n

For example, to create a VELatLong field (See the Microsoft Bing\nMapping API) containing the latitude/longitude value of a datapoint\non a map from a JsonReader data block

\n\n

which contained the properties lat and long, you would define a\nnew data type like this:

\n\n
// Add a new Field data type which stores a VELatLong object in the Record.\nExt.data.Types.VELATLONG = {\n    convert: function(v, data) {\n        return new VELatLong(data.lat, data.long);\n    },\n    sortType: function(v) {\n        return v.Latitude;  // When sorting, order by latitude\n    },\n    type: 'VELatLong'\n};\n
\n\n

Then, when declaring a Model, use:

\n\n
var types = Ext.data.Types; // allow shorthand type access\nExt.define('Unit',\n    extend: 'Ext.data.Model',\n    fields: [\n        { name: 'unitName', mapping: 'UnitName' },\n        { name: 'curSpeed', mapping: 'CurSpeed', type: types.INT },\n        { name: 'latitude', mapping: 'lat', type: types.FLOAT },\n        { name: 'longitude', mapping: 'long', type: types.FLOAT },\n        { name: 'position', type: types.VELATLONG }\n    ]\n});\n

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
\n
\n

This method has been deprecated

\n

as of 4.1. Use callParent instead.

\n\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

    \n
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.

\n

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
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\".

\n

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

    \n
...
\n

\n

Parameters

Returns

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
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\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

Parameters

( 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).
