`_addAttrs`

(

cfgs
values
lazy

)

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>.

`_addLazyAttr`

`_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.

lazy

)

protected

Inherited from Widget: yui3/src/widget/js/WidgetHTMLParser.js:83

Implement the BaseCore _preAddAttrs method hook, to add the srcNode and related attributes, so that HTML_PARSER (which relies on this.get("srcNode")) can merge in it's results before the rest of the attributes are added.

Parameters:

attrs Object

The full hash of statically defined ATTRS attributes being added for this instance
userVals Object

The hash of user values passed to the constructor
lazy Boolean

Whether or not to add the attributes lazily

Parameters:

config Object

The user configuration object

`_protectAttrs`

(

attrs

)

Object deprecated protected

Inherited from AttributeCore: yui3/src/attribute/js/AttributeCore.js:924

Utility method to protect an attribute configuration hash, by merging the entire object and the individual attr config objects.

Parameters:

attrs Object

A hash of attribute to configuration object pairs.

Returns:

Object:

A protected version of the attrs argument.

`_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 <code>type</code> to <code>fullType</code> 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.
