type String

String representing the name of the event

`_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.

Boolean:

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

`_initAttrHost`

(

attrs
values
lazy

)

private

Inherited from AttributeCore: yui3/src/attribute/js/AttributeCore.js:140

Constructor logic for attributes. Initializes the host state, and sets up the inital attributes passed to the constructor.

Parameters:

attrs Object

The attributes to add during construction (passed through to <a href="#method_addAttrs">addAttrs</a>). These can also be defined on the constructor being augmented with Attribute by defining the ATTRS property on the constructor.
values Object

The initial attribute values to apply (passed through to <a href="#method_addAttrs">addAttrs</a>). These are not merged/cloned. The caller is responsible for isolating user provided values if required.
lazy Boolean

Whether or not to add attributes lazily (passed through to <a href="#method_addAttrs">addAttrs</a>).

`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.

Array

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:168

Available since 3.3.0

Takes the type parameter passed to 'on' and parses out the various pieces that could be included in the type. If the event type is passed without a prefix, it will be expanded to include the prefix one is supplied or the event target is configured with a default prefix.

Parameters:

type String

the type
[pre] String optional

The prefix. Defaults to this._yuievt.config.prefix

Returns:

Array:

an array containing: <ul> <li>the detach category, if supplied,</li> <li>the prefixed event type,</li> <li>whether or not this is an after listener,</li> <li>the supplied event type</li> </ul>

`on`

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.

 this.on("change", this._onChange, this);

Callback functions for events published with emitFacade = true will receive an EventFacade as the first argument (typically named "e"). These callbacks can then call e.preventDefault() to disable the behavior published to that event's defaultFn. See the EventFacade API for all available properties and methods. Subscribers to non-emitFacade events will receive the arguments passed to fire() 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.

 this.on({
                                                     "attrChange" : this._onAttrChange,
                                                     "change"     : this._onChange
                                                 });

You can also pass an array of event names as the first argument to subscribe to all listed events with the same callback.

 this.on([ "change", "attrChange" ], this._onChange);

Returning false from a callback is supported as an alternative to calling e.preventDefault(); e.stopPropagation();. 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

Returns:

EventHandle:

`_getFullType`

(

type

)

String private

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:564

Returns the fully qualified type, given a short type string. That is, returns "foo:bar" when given "bar" if "foo" is the configured prefix.

NOTE: This method, unlike _getType, does no checking of the value passed in, and is designed to be used with the low level _publish() method, for critical path implementations which need to fast-track publish for performance reasons.

Parameters:

type String

The short type to prefix

Returns:

String:

The prefixed type, if a prefix is set, otherwise the type passed in

`_publish`

(

fullType
etOpts
ceOpts

)

CustomEvent private

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:588

The low level event publish implementation. It expects all the massaging to have been done outside of this method. e.g. the type to fullType conversion. It's designed to be a fast path publish, which can be used by critical code paths to improve performance.

Parameters:

fullType String

The prefixed type of the event to publish.
etOpts Object

The EventTarget specific configuration to mix into the published event.
ceOpts Object

The publish specific configuration to mix into the published event.

Returns:

CustomEvent:

The published event. If called without <code>etOpts</code> or <code>ceOpts</code>, this will be the default <code>CustomEvent</code> instance, and can be configured independently.

`_monitor`

(

what
eventType
o

)

private

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:636

This is the entry point for the event monitoring system. You can monitor 'attach', 'detach', 'fire', and 'publish'. When configured, these events generate an event. click -> click_attach, click_detach, click_publish -- these can be subscribed to like other events to monitor the event system. Inividual published events can have monitoring turned on or off (publish can't be turned off before it it published) by setting the events 'monitor' config.

Parameters:

what String

'attach', 'detach', 'fire', or 'publish'
eventType String | CustomEvent

The prefixed name of the event being monitored, or the CustomEvent object.
o Object

Information about the event interaction, such as fire() args, subscription category, publish config

`fire`

(

type
arguments

)

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.

Returns:

Boolean:

True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.

EventHandle

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:812

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

`before`

()

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:849

For DOM and custom events: type, callback, context, 0-n arguments

For methods: callback, object (method host), methodName, context, 0-n arguments

Returns:
