Terms, Icons, and Labels

Many classes have shortcut names used when creating (instantiating) a class with a configuration object. The shortcut name is referred to as an alias (or xtype if the class extends Ext.Component). The alias/xtype is listed next to the class name of applicable classes for quick reference.

Access Levels

Framework classes or their members may be specified as private or protected. Else, the class / member is public. Public, protected, and private are access descriptors used to convey how and when the class or class member should be used.

Member Types

Member Syntax

Below is an example class member that we can disect to show the syntax of a class member (the lookupComponent method as viewed from the Ext.button.Button class in this case).

lookupComponent ( item ) : Ext.Component
protected

Called when a raw config object is added to this container either during initialization of the items config, or when new items are added), or {@link #insert inserted.

This method converts the passed object into an instanced child component.

This may be overridden in subclasses when special processing needs to be applied to child creation.

Parameters

item :  Object

The config object being added.

Returns
Ext.Component

The component to be added.

Let's look at each part of the member row:

Member Flags

The API documentation uses a number of flags to further commnicate the class member's function and intent. The label may be represented by a text label, an abbreviation, or an icon.

Class Icons

- Indicates a framework class

- A singleton framework class. *See the singleton flag for more information

- A component-type framework class (any class within the Ext JS framework that extends Ext.Component)

- Indicates that the class, member, or guide is new in the currently viewed version

Member Icons

- Indicates a class member of type config

- Indicates a class member of type property

- Indicates a class member of type method

- Indicates a class member of type event

- Indicates a class member of type theme variable

- Indicates a class member of type theme mixin

- Indicates that the class, member, or guide is new in the currently viewed version

Class Member Quick-Nav Menu

Just below the class name on an API doc page is a row of buttons corresponding to the types of members owned by the current class. Each button shows a count of members by type (this count is updated as filters are applied). Clicking the button will navigate you to that member section. Hovering over the member-type button will reveal a popup menu of all members of that type for quick navigation.

Getter and Setter Methods

Getting and setter methods that correlate to a class config option will show up in the methods section as well as in the configs section of both the API doc and the member-type menus just beneath the config they work with. The getter and setter method documentation will be found in the config row for easy reference.

History Bar

Your page history is kept in localstorage and displayed (using the available real estate) just below the top title bar. By default, the only search results shown are the pages matching the product / version you're currently viewing. You can expand what is displayed by clicking on the button on the right-hand side of the history bar and choosing the "All" radio option. This will show all recent pages in the history bar for all products / versions.

Within the history config menu you will also see a listing of your recent page visits. The results are filtered by the "Current Product / Version" and "All" radio options. Clicking on the button will clear the history bar as well as the history kept in local storage.

If "All" is selected in the history config menu the checkbox option for "Show product details in the history bar" will be enabled. When checked, the product/version for each historic page will show alongside the page name in the history bar. Hovering the cursor over the page names in the history bar will also show the product/version as a tooltip.

Search and Filters

Both API docs and guides can be searched for using the search field at the top of the page.

On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page.

The checkbox at the bottom of the API class navigation tree filters the class list to include or exclude private classes.

Clicking on an empty search field will show your last 10 searches for quick navigation.

API Doc Class Metadata

Each API doc page (with the exception of Javascript primitives pages) has a menu view of metadata relating to that class. This metadata view will have one or more of the following:

Expanding and Collapsing Examples and Class Members

Runnable examples (Fiddles) are expanded on a page by default. You can collapse and expand example code blocks individually using the arrow on the top-left of the code block. You can also toggle the collapse state of all examples using the toggle button on the top-right of the page. The toggle-all state will be remembered between page loads.

Class members are collapsed on a page by default. You can expand and collapse members using the arrow icon on the left of the member row or globally using the expand / collapse all toggle button top-right.

Desktop -vs- Mobile View

Viewing the docs on narrower screens or browsers will result in a view optimized for a smaller form factor. The primary differences between the desktop and "mobile" view are:

Viewing the Class Source

The class source can be viewed by clicking on the class name at the top of an API doc page. The source for class members can be viewed by clicking on the "view source" link on the right-hand side of the member row.

NPM Package

Hierarchy

Ext.Base
Ext.route.Route

Summary

Enables reactive actions to handle changes in the hash by using the routes configuration in a controller. An example configuration would be:

Ext.define('MyApp.view.main.MainController', {
    extend: 'Ext.app.ViewController',
    alias: 'controller.app-main',

    routes: {
        'user/:{id}': 'onUser'
    },

    onUser: function (values) {
        var id = values.id;
        // ...
    }
});

The routes object can also receive an object to further configure the route, for example you can configure a before action that will be executed before the action or can cancel the route execution:

Ext.define('MyApp.view.main.MainController', {
    extend: 'Ext.app.ViewController',
    alias: 'controller.app-main',

    routes: {
        'user/:{id}': {
            action: 'onUser',
            before: 'onBeforeUser',
            name: 'user'
        }
    },

    onBeforeUser: function (values) {
        return Ext.Ajax
            .request({
                url: '/check/permission',
                params: {
                    route: 'user',
                    meta: {
                        id: values.id
                    }
                }
            });
    },

    onUser: function (values) {
        var id = values.id;
        // ...
    }
});

URL Parameters in a route can also define a type that will be used when matching hashes when finding routes that recognize a hash and also parses the value into numbers:

Ext.define('MyApp.view.main.MainController', {
    extend: 'Ext.app.ViewController',
    alias: 'controller.app-main',

    routes: {
        'user/:{id:num}': {
            action: 'onUser',
            before: 'onBeforeUser',
            name: 'user'
        }
    },

    onBeforeUser: function (values) {
        return Ext.Ajax
            .request({
                url: '/check/permission',
                params: {
                    route: 'user',
                    meta: {
                        id: values.id
                    }
                }
            });
    },

    onUser: function (values) {
        var id = values.id;
        // ...
    }
});

In this example, the id parameter added :num to the parameter which will now mean the route will only recognize a value for the id parameter that is a number such as #user/123 and will not recognize #user/abc. The id passed to the action and before handlers will also get cast into a number instead of a string. If a type is not provided, it will use the default matcher.

For more on types, see the types config.

For backwards compatibility, there is positional mode which is like named mode but how you define the url parameters and how they are passed to the action and before handlers is slightly different:

Ext.define('MyApp.view.main.MainController', {
    extend: 'Ext.app.ViewController',
    alias: 'controller.app-main',

    routes: {
        'user/:id:action': {
            action: 'onUser',
            before: 'onBeforeUser',
            name: 'user',
            conditions: {
                ':action': '(edit|delete)?'
            }
        }
    },

    onBeforeUser: function (id, action) {
        return Ext.Ajax
            .request({
                url: '/check/permission',
                params: {
                    route: 'user',
                    meta: {
                        action: action,
                        id: id
                    }
                }
            });
    },

    onUser: function (id) {
        // ...
    }
});

The parameters are defined without curly braces (:id, :action) and they are passed as individual arguments to the action and before handlers.

It's important to note you cannot mix positional and named parameter formats in the same route since how they are passed to the handlers is different.

Routes can define sections of a route pattern that are optional by surrounding the section that is to be optional with parenthesis. For example, if a route should match both #user and #user/1234 to either show a grid of all users or details or a single user, you can define the route such as:

Ext.define('MyApp.view.main.MainController', {
    extend: 'Ext.app.ViewController',
    alias: 'controller.app-main',

    routes: {
        'user(/:{id:num})': {
            action: 'onUser',
            name: 'user'
        }
    },

    onUser: function (params) {
        if (params.id) {
            // load user details
        } else {
            // load grid of users
        }
    }
});
No members found using the current filters

Optional set of conditions for each token in the url string. Each key should be one of the tokens, each value should be a regex that the token should accept.

For positional mode, if you have a route with a url like 'files/:fileName' and you want it to match urls like files/someImage.jpg then you can set these conditions to allow the :fileName token to accept strings containing a period:

conditions: {
    ':fileName': '([0-9a-zA-Z\.]+)'
}

For named mode, if you have a route with a url like 'files/:{fileName}' and you want it to match urls like files/someImage.jpg then you can set these conditions to allow the :{fileName} token to accept strings containing a period:

conditions: {
    'fileName': '([0-9a-zA-Z\.]+)'
}

You can also define a condition to parse the value or even split it on a character:

conditions: {
    'fileName': {
        re: '([0-9a-zA-Z\.]+)',
        split: '.', // split the value so you get an array ['someImage', 'jpg']
        parse: function (values) {
            return values[0]; // return a string without the extension
        }
    }
}

Defaults to:

{}

getConditions : Object

Returns the value of conditions

Returns

Object

setConditions (conditions)

}, {
    action: function() {
        //...
    },
    before: function() {
        //...
    },
    scope: {}
}, {
    exit: function() {
        //...
    },
    scope: {}
}]

The action, before and exit handlers can be a string that will be resolved from the scope:

handlers: [{
    action: 'onAction',
    before: 'onBefore',
    exit: 'onExit',
    scope: {
        onAction: function () {
            //...
        },
        onBefore: function () {
            //...
        },
        onExit: function () {
            //...
        }
    }
}]

Parameters

name :  String

properties

Instance Properties

$className
private pri

Defaults to:

'Ext.Base'

$configPrefixed : Boolean
private pri

The value true causes config values to be stored on instances using a property name prefixed with an underscore ("_") character. A value of false stores config values as properties using their exact name (no prefix).

Defaults to:

true

Available since: 5.0.0

$configStrict : Boolean
private pri

The value true instructs the initConfig method to only honor values for properties declared in the config block of a class. When false, properties that are not declared in a config block will be placed on the instance.

Defaults to:

true

Available since: 5.0.0

$configTransforms : Object / Array
private pri

A prototype-chained object storing transform method names and priorities stored on the class prototype. On first instantiation, this object is converted into an array that is sorted by priority and stored on the constructor.

Defaults to:

{}

clearPropertiesOnDestroy : Boolean / "async"
protected pro

Setting this property to false will prevent nulling object references on a Class instance after destruction. Setting this to "async" will delay the clearing for approx 50ms.

Defaults to:

true

Available since: 6.2.0

clearPrototypeOnDestroy : Boolean
private pri

Setting this property to true will result in setting the object's prototype to null after the destruction sequence is fully completed. After that, most attempts at calling methods on the object instance will result in "method not defined" exception. This can be very helpful with tracking down otherwise hard to find bugs like runaway Ajax requests, timed functions not cleared on destruction, etc.

Note that this option can only work in browsers that support Object.setPrototypeOf method, and is only available in debugging mode.

Defaults to:

false

Available since: 6.2.0

defaultMatcher : String

The default RegExp string to use to match parameters with.

Defaults to:

'([%a-zA-Z0-9\\-\\_\\s,]+)'

destroyed : Boolean

This property is set to true after the destroy method is called.

Defaults to:

false

isConfiguring : Boolean
readonly ro protected pro

This property is set to true during the call to initConfig.

Defaults to:

false

Available since: 5.0.0

isFirstInstance : Boolean
readonly ro protected pro

This property is set to true if this instance is the first of its class.

Defaults to:

false

Available since: 5.0.0

isInstance : Boolean
readonly ro protected pro

This value is true and is used to identify plain objects from instances of a defined class.

Defaults to:

true

isRoute : Boolean
protected pro

Defaults to:

true

matcherRegex : RegExp
private pri

A regular expression to match the token to the configured url.

mode : String
private pri

The mode based on the url pattern this route is configured with. Valid values are:

  • positional The url was configured with the parameter format as :param. The values in the handler functions will be individual arguments. Example:

    Ext.define('MyApp.view.MainController', {

      extend: 'Ext.app.ViewController',
      alias: 'controller.myapp-main',
    
      routes: {
          'view/:view/:child': {
              action: 'onView',
              before: 'onBeforeView',
              name: 'view'
          }
      },
    
      onBeforeView: function (view, child) {
          return Ext.Ajax.request({
              url: 'check/permission',
              params: {
                  view: view,
                  info: { childView: child }
              }
          });
      },
    
      onView: function (view, child) {}
    

    });

The values from the matched url that the view route would execute with are separate arguments in the before and action handlers.

  • named The url was configured with the parameter format as :{param:type} where the :type is optional. Example:

    Ext.define('MyApp.view.MainController', {

      extend: 'Ext.app.ViewController',
      alias: 'controller.myapp-main',
    
      routes: {
          'view/:{view}/:{child:alphanum}': {
              action: 'onView',
              before: 'onBeforeView',
              name: 'view'
          }
      },
    
      onBeforeView: function (values) {
          return Ext.Ajax.request({
              url: 'check/permission',
              params: {
                  view: values.view,
                  info: { childView: values.child }
              }
          });
      },
    
      onView: function (values) {}
    

    });

The values from the matched url the view route would execute with are collected into an object with the parameter name as the key and the associated value as the value. See types for more about this named mode.

Available since: 6.6.0

numRe : RegExp

A regular expression to match against float numbers for alphanum, num and ... types in order to cast into floats.

Defaults to:

/^[0-9]*(?:\.[0-9]*)?$/

Available since: 6.6.0

optionalParamRegex : RegExp
private pri

A regular expression to find groups intended to be optional values within the hash. This means that if they are in the hash they will match and return the values present. But, if they are not and the rest of the hash matches, the route will still execute passing undefined as the values of any parameters within an optional group.

routes: {
    'user(\/:{id:num})': {
        action: 'onUser',
        name: 'user'
    }
}

In this example, the id parameter and the slash will be optional since they are wrapped in the parentheses. This route would execute if the hash is #user or #user/1234.

Defaults to:

/\((.+?)\)/g

Available since: 6.6.0

paramMatchingRegex : RegExp
private pri

A regular expression to check if there are parameters in the configured url.

Defaults to:

/:([0-9A-Za-z_]+)/g

paramsInMatchString : Array / Object
private pri

An array or object of parameters in the configured url.

self : Ext.Class
protected pro

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

Ext.define('My.Cat', {
    statics: {
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
    },

    constructor: function() {
        alert(this.self.speciesName); // dependent on 'this'
    },

    clone: function() {
        return new this.self();
    }
});


Ext.define('My.SnowLeopard', {
    extend: 'My.Cat',
    statics: {
        speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'
    }
});

var cat = new My.Cat();                     // alerts 'Cat'
var snowLeopard = new My.SnowLeopard();     // alerts 'Snow Leopard'

var clone = snowLeopard.clone();
alert(Ext.getClassName(clone));             // alerts 'My.SnowLeopard'

Defaults to:

Base

typeParamRegex : RegExp
private pri

A regular expression to determine if the parameter may contain type information. If a parameter does have type information, the url parameters sent to the Ext.route.Handler#before and Ext.route.Handler#after will be in an object instead of separate arguments.

Defaults to:

/:{([0-9A-Za-z_]+)(?::?([0-9A-Za-z_]+|.{3})?)}/g

Available since: 6.6.0

types : Object

An object of types that will be used to match and parse values from a matched url. There are four default types:

  • alpha This will only match values that have only alpha characters using the regex ([a-zA-Z]+).
  • alphanum This will only match values that have alpha and numeric characters using the regex ([a-zA-Z0-9]+|[0-9]*(?:\\.[0-9]*)?). If a value is a number, which a number can have a period (10.4), the value will be case into a float using parseFloat.
  • num This will only match values that have numeric characters using the regex ([0-9]*(?:\\.[0-9]*)?). The value, which can have a period (10.4), will be case into a float using parseFloat.
  • ... This is meant to be the last argument in the url and will match all characters using the regex (.+)?. If a value is matched, this is an optional type, the value will be split by / and an array will be sent to the handler methods. If no value was matched, the value will be undefined.

When defining routes, a type is optional and will use the default matcher but the url parameter must be enclosed in curly braces which will send a single object to the route handlers:

Ext.define('MyApp.view.MainController', {
    extend: 'Ext.app.ViewController',
    alias: 'controller.myapp-main',

    routes: {
        'view/:{view}/:{child:alphanum}:{args...}': {
            action: 'onView',
            before: 'onBeforeView',
            name: 'view'
        }
    },

    onBeforeView: function (values) {
        return Ext.Ajax.request({
            url: 'check/permission',
            params: {
                view: values.view,
                info: { childView: values.child }
            }
        });
    },

    onView: function (values) {}
});

In this example, there are 3 parameters defined. The :{view} parameter has no type which will match characters using the default matcher but is required to be in the matched url. The :{child:alphanum} will only match characters that are alpha or numeric but is required to be in the matched url. The :{args...} is the only optional parameter in this route but can match any character and will be an array of values split by / unless there are no values in which case undefined will be sent in the object.

If the hash is #view/user/edit, the values argument sent to the handlers would be:

{
    view: 'user',
    child: 'edit',
    args: undefined
}

Since there were no more values for the args parameter, it's value is undefined.

If the hash is #view/user/1234, the values argument sent to the handlers would be:

{
    view: 'user',
    child: 1234,
    args: undefined
}

Notice the child value is a number instead of a string.

If the hash is #view/user/1234/edit/settings, the values argument sent to the handlers would be:

{
    view: 'user',
    child: 1234,
    args: ['edit', 'settings']
}

The args parameter matched the edit/settings and split it by the / producing the array.

To add custom types, you can override Ext.route.Route:

Ext.define('Override.route.Route', {
    override: 'Ext.route.Route',

    config: {
        types: {
            uuid: {
                re: '([0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12})'
            }
        }
    }
});

You can now use the uuid type in your routes:

methods

Instance Methods

addDeprecations ( deprecations )
private pri

This method applies a versioned, deprecation declaration to this class. This is typically called by the deprecated config.

Parameters

deprecations :  Object

addHandler ( handler ) : Ext.route.Route

Adds a handler to the handlers stack.

Parameters

handler :  Object

An object to describe the handler. A handler should define a fn and scope. If the fn is a String, the function will be resolved from the scope.

Returns

:Ext.route.Route

this

callOverridden ( args ) : Object
deprecated dep protected pro

Call the original method that was previously overridden with Ext.Base#override

Ext.define('My.Cat', {
    constructor: function() {
        alert("I'm a cat!");
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callOverridden();

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callOverridden(arguments)

Returns

:Object

Returns the result of calling the overridden method

Deprecated since version 4.1.0
Use method-callParent instead.

callParent ( args ) : Object
protected pro

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

 Ext.define('My.Base', {
     constructor: function(x) {
         this.x = x;
     },

     statics: {
         method: function(x) {
             return x;
         }
     }
 });

 Ext.define('My.Derived', {
     extend: 'My.Base',

     constructor: function() {
         this.callParent([21]);
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // alerts 21

This can be used with an override as follows:

 Ext.define('My.DerivedOverride', {
     override: 'My.Derived',

     constructor: function(x) {
         this.callParent([x*2]); // calls original My.Derived constructor
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // now alerts 42

This also works with static and private methods.

 Ext.define('My.Derived2', {
     extend: 'My.Base',

     // privates: {
     statics: {
         method: function(x) {
             return this.callParent([x*2]); // calls My.Base.method
         }
     }
 });

 alert(My.Base.method(10));     // alerts 10
 alert(My.Derived2.method(10)); // alerts 20

Lastly, it also works with overridden static methods.

 Ext.define('My.Derived2Override', {
     override: 'My.Derived2',

     // privates: {
     statics: {
         method: function(x) {
             return this.callParent([x*2]); // calls My.Derived2.method
         }
     }
 });

 alert(My.Derived2.method(10); // now alerts 40

To override a method and replace it and also call the superclass method, use method-callSuper. 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 from the current method, for example: this.callParent(arguments)

Returns

:Object

Returns the result of calling the parent method

callSuper ( args ) : Object
protected pro

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

Consider:

 Ext.define('Ext.some.Class', {
     method: function() {
         console.log('Good');
     }
 });

 Ext.define('Ext.some.DerivedClass', {
     extend: 'Ext.some.Class',

     method: function() {
         console.log('Bad');

         // ... logic but with a bug ...

         this.callParent();
     }
 });

To patch the bug in Ext.some.DerivedClass.method, the typical solution is to create an override:

 Ext.define('App.patches.DerivedClass', {
     override: 'Ext.some.DerivedClass',

     method: function() {
         console.log('Fixed');

         // ... logic but with bug fixed ...

         this.callSuper();
     }
 });

The patch method cannot use method-callParent to call the superclass method since that would call the overridden method containing the bug. In other words, the above patch would only produce "Fixed" then "Good" in the console log, whereas, using callParent would produce "Fixed" then "Bad" then "Good".

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callSuper(arguments)

Returns

:Object

Returns the result of calling the superclass method

clearLastTokens

Clears the last token properties of this route and all handlers.

createMatcherRegex ( url ) : RegExp

Takes the configured url string including wildcards and returns a regex that can be used to match against a url.

This is only used in positional mode.

Parameters

url :  String

The url string.

Returns

:RegExp

The matcher regex.

destroy

This method is called to cleanup an object and its resources. After calling this method, the object should not be used any further in any way, including access to its methods and properties.

To prevent potential memory leaks, all object references will be nulled at the end of destruction sequence, unless clearPropertiesOnDestroy is set to false.

destroyMembers ( args )

Destroys member properties by name.

If a property name is the name of a config, the getter is not invoked, so if the config has not been initialized, nothing will be done.

The property will be destroyed, and the corrected name (if the property is a config and config names are prefixed) will set to null in this object's dictionary.

Parameters

args :  String...

One or more names of the properties to destroy and remove from the object.

execute ( token, argConfig ) : Ext.promise.Promise

The method to execute the action using the configured before function which will kick off the actual actions on the controller.

Parameters

token :  String

The token this route is being executed with.

argConfig :  Object

The object from the Ext.route.Routes recognize method call.

Returns

:Ext.promise.Promise

getConfig ( [name], [peek], [ifInitialized] ) : Object

Returns a specified config property value. If the name parameter is not passed, all current configuration options will be returned as key value pairs.

Parameters

name :  String (optional)

The name of the config property to get.

peek :  Boolean (optional)

true to peek at the raw value without calling the getter.

Defaults to: false

ifInitialized :  Boolean (optional)

true to only return the initialized property value, not the raw config value, and not to trigger initialization. Returns undefined if the property has not yet been initialized.

Defaults to: false

Returns

:Object

The config property value.

getInitialConfig ( [name] ) : Object/Mixed

Returns the initial configuration passed to the constructor when instantiating this class.

Given this example Ext.button.Button definition and instance:

Ext.define('MyApp.view.Button', {
    extend: 'Ext.button.Button',
    xtype: 'mybutton',

    scale: 'large',
    enableToggle: true
});

var btn = Ext.create({
    xtype: 'mybutton',
    renderTo: Ext.getBody(),
    text: 'Test Button'
});

Calling btn.getInitialConfig() would return an object including the config options passed to the create method:

xtype: 'mybutton',
renderTo: // The document body itself
text: 'Test Button'

Calling btn.getInitialConfig('text')returns 'Test Button'.

Parameters

name :  String (optional)

Name of the config option to return.

Returns

:Object/Mixed

The full config object or a single config value when name parameter specified.

        // always equals to 'Cat' no matter what 'this' refers to
        // equivalent to: My.Cat.speciesName
        alert(statics.speciesName);


        alert(this.self.speciesName);   // dependent on 'this'

        statics.totalCreated++;
    },

    clone: function() {
        var cloned = new this.self();   // dependent on 'this'

        // equivalent to: My.Cat.speciesName
        cloned.groupName = this.statics().speciesName;

        return cloned;

onExtended ( fn, scope ) :
chainable ch static sta private pri

Parameters

fn :  Object

scope :  Object

Returns

:

override ( members ) : Ext.Base
chainable ch static sta

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

Ext.define('My.Cat', {
    constructor: function() {
        alert("I'm a cat!");
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Direct use of this method should be rare. Use Ext.define instead:

Ext.define('My.CatOverride', {
    override: 'My.Cat',
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

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

Parameters

members :  Object

The properties to add to this class. This should be specified as an object literal containing one or more properties.

Returns

:Ext.Base

this class
