Ext.Base
Ext.data.IdGenerator
Ext.data.UuidGenerator

Files

This class generates UUID's according to RFC 4122. This class has a default id property.\nThis means that a single instance is shared unless the id property is overridden. Thus,\ntwo Ext.data.Model instances configured like the following share one generator:

\n\n
Ext.define('MyApp.data.MyModelX', {\n    extend: 'Ext.data.Model',\n    idgen: 'uuid'\n});\n\nExt.define('MyApp.data.MyModelY', {\n    extend: 'Ext.data.Model',\n    idgen: 'uuid'\n});\n
\n\n

This allows all models using this class to share a commonly configured instance.

\n\n

Using Version 1 (\"Sequential\") UUID's

\n\n

If a server can provide a proper timestamp and a \"cryptographic quality random number\"\n(as described in RFC 4122), the shared instance can be configured as follows:

\n\n
Ext.data.IdGenerator.get('uuid').reconfigure({\n    version: 1,\n    clockSeq: clock, // 14 random bits\n    salt: salt,      // 48 secure random bits (the Node field)\n    timestamp: ts    // timestamp per Section 4.1.4\n});\n\n// or these values can be split into 32-bit chunks:\n\nExt.data.IdGenerator.get('uuid').reconfigure({\n    version: 1,\n    clockSeq: clock,\n    salt: { lo: saltLow32, hi: saltHigh32 },\n    timestamp: { lo: timestampLow32, hi: timestamptHigh32 }\n});\n
\n\n

This approach improves the generator's uniqueness by providing a valid timestamp and\nhigher quality random data. Version 1 UUID's should not be used unless this information\ncan be provided by a server and care should be taken to avoid caching of this data.

\n\n

See http://www.ietf.org/rfc/rfc4122.txt for details.

\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

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

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).
