)

private

Inherited from AttributeCore: yui3/src/attribute/js/AttributeCore.js:877

Implementation behind the public addAttrs method. This method is invoked directly by get if it encounters a scenario in which an attribute's valueFn attempts to obtain the value an attribute in the same group of attributes, which has not yet been added (on demand initialization).

Parameters:

cfgs Object

An object with attribute name/configuration pairs.
values Object

An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
lazy Boolean

Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See <a href="#method_addAttr">addAttr</a>.

`_filterUIEvent`

(

evt

)

Boolean private

Inherited from Widget: yui3/src/widget/js/WidgetUIEvents.js:117

This method is used to determine if we should fire the UI Event or not. The default implementation makes sure that for nested delegates (nested unrelated widgets), we don't fire the UI event listener more than once at each level.

For example, without the additional filter, if you have nested widgets, each widget will have a delegate listener. If you click on the inner widget, the inner delegate listener's filter will match once, but the outer will match twice (based on delegate's design) - once for the inner widget, and once for the outer.

Parameters:

evt DOMEventFacade

Returns:

Boolean:

true if it's OK to fire the custom UI event, false if not.

`addAttr`

(

name
config
lazy

)

Object chainable

Inherited from AttributeCore: yui3/src/attribute/js/AttributeCore.js:157

Adds an attribute with the provided configuration to the host object. The config argument object supports the following properties: <dl> <dt>value <Any></dt> <dd>The initial value to set on the attribute</dd> <dt>valueFn <Function | String></dt> <dd> A function, which will return the initial value to set on the attribute. This is useful for cases where the attribute configuration is defined statically, but needs to reference the host instance ("this") to obtain an initial value. If both the value and valueFn properties are defined, the value returned by the valueFn has precedence over the value property, unless it returns undefined, in which case the value property is used. valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value. </dd> <dt>readOnly <boolean></dt> <dd>Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.</dd> <dt>writeOnce <boolean> or <string></dt> <dd> Whether or not the attribute is "write once". Attributes having writeOnce set to true, can only have their values set once, be it through the default configuration, constructor configuration arguments, or by invoking set. The writeOnce attribute can also be set to the string "initOnly", in which case the attribute can only be set during initialization (when used with Base, this means it can only be set during construction) </dd> <dt>setter <Function | String></dt> <dd> The setter function used to massage or normalize the value passed to the set method for the attribute. The value returned by the setter will be the final stored value. Returning <a href="#property_Attribute.INVALID_VALUE">Attribute.INVALID_VALUE</a>, from the setter will prevent the value from being stored. setter can also be set to a string, representing the name of the instance method to be used as the setter function. </dd> <dt>getter <Function | String></dt> <dd> The getter function used to massage or normalize the value returned by the get method for the attribute. The value returned by the getter function is the value which will be returned to the user when they invoke get. getter can also be set to a string, representing the name of the instance method to be used as the getter function. </dd> <dt>validator <Function | String></dt> <dd> The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored. validator can also be set to a string, representing the name of the instance method to be used as the validator function. </dd> <dt>lazyAdd <boolean></dt> <dd>Whether or not to delay initialization of the attribute until the first call to get/set it. This flag can be used to over-ride lazy initialization on a per attribute basis, when adding multiple attributes through the <a href="#method_addAttrs">addAttrs</a> method.</dd> </dl> The setter, getter and validator are invoked with the value and name passed in as the first and second arguments, and with the context ("this") set to the host object. Configuration properties outside of the list mentioned above are considered private properties used internally by attribute, and are not intended for public use.

Parameters:

name String

The name of the attribute.
config Object

An object with attribute configuration property/value pairs, specifying the configuration for the attribute. NOTE: The configuration object is modified when adding an attribute, so if you need to protect the original values, you will need to merge the object.
lazy Boolean

(optional) Whether or not to add this attribute lazily (on the first call to get/set).

Returns:

Object:

A reference to the host object.

`addAttrs`

(

cfgs
values

Parameters:

cfgs Object

An object with attribute name/configuration pairs.
values Object

An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
lazy Boolean

Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See <a href="#method_addAttr">addAttr</a>.

Returns:

Object:

A reference to the host object.

Boolean

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:673

Fire a custom event by name. The callback functions will be executed from the context specified when the event was created, and with the following parameters. The first argument is the event type, and any additional arguments are passed to the listeners as parameters. If the first of these is an object literal, and the event is configured to emit an event facade, that object is mixed into the event facade and the facade is provided in place of the original object. If the custom event object hasn't been created, then the event hasn't been published and it has no subscribers. For performance sake, we immediate exit in this case. This means the event won't bubble, so if the intention is that a bubble target be notified, the event must be published on this object first.

Parameters:

type String | Object

The type of the event, or an object that contains a 'type' property.
arguments Object

an arbitrary set of parameters to pass to the handler. If the first of these is an object literal and the event is configured to emit an event facade, the event facade will replace that parameter after the properties the object literal contains are copied to the event facade.

`getClassName`

(

args

)

Inherited from Widget but overwritten in yui3/src/widget/js/Widget.js:309

Generate a standard prefixed classname for the Widget, prefixed by the default prefix defined by the <code>Y.config.classNamePrefix</code> attribute used by <code>ClassNameManager</code> and <code>Widget.NAME.toLowerCase()</code> (e.g. "yui-widget-xxxxx-yyyyy", based on default values for the prefix and widget class name). The instance based version of this method can be used to generate standard prefixed classnames, based on the instances NAME, as opposed to Widget.NAME. This method should be used when you need to use a constant class name across different types instances.

Parameters:

args String multiple

0..n strings which should be concatenated, using the default separator defined by ClassNameManager, to create the class name

`getEvent`

(

type
prefixed

)

CustomEvent

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:793

Returns the custom event of the provided type has been created, a falsy value otherwise

Parameters:

type String

the type, or name of the event
prefixed String

if true, the type is prefixed already

Returns:

CustomEvent:

the custom event or null

`getSkinName`

(

[skinPrefix]

)

String

Inherited from Widget: yui3/src/widget/js/WidgetSkin.js:12

Returns the name of the skin that's currently applied to the widget.

Searches up the Widget's ancestor axis for, by default, a class yui3-skin-(name), and returns the (name) portion. Otherwise, returns null.

This is only really useful after the widget's DOM structure is in the document, either by render or by progressive enhancement.

Parameters:

[skinPrefix] String optional

The prefix which the implementation uses for the skin ("yui3-skin-" is the default). NOTE: skinPrefix will be used as part of a regular expression: <pre><code>new RegExp('\b' + skinPrefix + '(\S+)') </code></pre> Although an unlikely use case, literal characters which may result in an invalid regular expression should be escaped.

Returns:

String:

The name of the skin, or null, if a matching skin class is not found.

EventHandle

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:188

Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object. <pre><code> this.on("change", this._onChange, this); </code></pre> Callback functions for events published with <code>emitFacade = true</code> will receive an <code>EventFacade</code> as the first argument (typically named "e"). These callbacks can then call <code>e.preventDefault()</code> to disable the behavior published to that event's <code>defaultFn</code>. See the <code>EventFacade</code> API for all available properties and methods. Subscribers to non-<code>emitFacade</code> events will receive the arguments passed to <code>fire()</code> after the event name. To subscribe to multiple events at once, pass an object as the first argument, where the key:value pairs correspond to the eventName:callback. <pre><code> this.on({ "attrChange" : this._onAttrChange, "change" : this._onChange }); </code></pre> You can also pass an array of event names as the first argument to subscribe to all listed events with the same callback. <pre><code> this.on([ "change", "attrChange" ], this._onChange); </code></pre> Returning <code>false</code> from a callback is supported as an alternative to calling <code>e.preventDefault(); e.stopPropagation();</code>. However, it is recommended to use the event methods whenever possible.

Parameters:

type String

The name of the event
fn Function

The callback to execute in response to the event
[context] Object optional

Override <code>this</code> object in callback
[arg*] Any optional

0..n additional arguments to supply to the subscriber

`render`

(

parentNode

)

final chainable

Inherited from Widget: yui3/src/widget/js/Widget.js:509

Establishes the initial DOM for the widget. Invoking this method will lead to the creating of all DOM elements for the widget (or the manipulation of existing DOM elements for the progressive enhancement use case). This method should only be invoked once for an initialized widget. It delegates to the widget specific renderer method to do the actual work.

Parameters:

parentNode Object | String

Optional. The Node under which the Widget is to be rendered. This can be a Node instance or a CSS selector string. If the selector string returns more than one Node, the first node will be used as the parentNode. NOTE: This argument is required if both the boundingBox and contentBox are not currently in the document. If it's not provided, the Widget will be rendered to the body of the current document in this case.

`renderer`

() protected

Inherited from Widget: yui3/src/widget/js/Widget.js:584

Returns:

Node:

the rail node subtree

`renderThumb`

() Node

Inherited from SliderBase: yui3/src/slider/js/slider-base.js:160
