This class is intended to be used in MXML to define object literals
whose properties must be bindable.
It's typically used to define List or
DataGrid data provider items within an MXML file for small applications or examples
with item renderers that bind to their data.
Non-trival applications, or any application for which performance is a concern,
should define a [Bindable]
class with a fixed set of
strongly typed properties and use that class to define data provider items.

DataItem()
Constructor
| DataItem | ||
addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object
so that the listener receives notification of an event. | ObjectProxy | ||
dispatchEvent(event:Event):Boolean
Dispatches an event into the event flow. | ObjectProxy | ||
hasEventListener(type:String):Boolean
Checks whether there are any event listeners registered
for a specific type of event. | ObjectProxy | ||
propertyChangeHandler(event:PropertyChangeEvent):void
Called when a complex property is updated. | ObjectProxy | ||
readExternal(input:IDataInput):void
Since Flex only uses ObjectProxy to wrap anonymous objects,
the server flex.messaging.io.ObjectProxy instance serializes itself
as a Map that will be returned as a plain ActionScript object. | ObjectProxy | ||
removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void
Removes an event listener. | ObjectProxy | ||
willTrigger(type:String):Boolean
Checks whether an event listener is registered with this object
or any of its ancestors for the specified event type. | ObjectProxy | ||
writeExternal(output:IDataOutput):void
Since Flex only serializes the inner ActionScript object that it wraps,
the server flex.messaging.io.ObjectProxy populates itself
with this anonymous object's contents and appears to the user
as a Map. | ObjectProxy |
