The ManagedObjectProxy class provides the ability to track changes to an item that is anonymous and managed by a DataService. Any number of objects can "listen" for changes on this object, by using the addEventListener() method. This class provides the same level of functionality for anonymous objects managed by a DataService as that given to any class with [Managed] metadata applied to it.

	Method		Defined By
		ManagedObjectProxy(item:Object = null, uid:String = null) Intializes this proxy with the specified object and id.	ManagedObjectProxy
		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 [override] ManagedObjectProxy may need to exclude properties on the wrapped anonymous Object if a DataService destination is defined and lazy associations have been configured.	ManagedObjectProxy
		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 [override] ManagedObjectProxy checks if properties on the wrapped anonymous Object are lazy associations and if so they are excluded from serialization.	ManagedObjectProxy

	Method		Defined By
		getProperty(name:): [override] DataService must save the state of an unmanaged collection before a change to any of the contained items has been modified.	ManagedObjectProxy
		setProperty(name:, value:):void [override] If the property being set is an ArrayCollection then we need to ensure that any list that this proxy was previously listening for events on should stop.	ManagedObjectProxy
		setupPropertyList():void This method creates an array of all of the property names for the proxied object.	ObjectProxy

	`item:Object` (default = `null`) — Object to proxy. if no item is specified, an anonymous object will be constructed and assigned.

	`uid:String` (default = `null`) — String containing the unique id for this object instance. Required for IManaged compliance as every object must provide a unique way of identifying it. If no value is specified a random id will be assigned.

	`name:*` — Object containing the name of the property that should be updated on the proxied object.

	`value:*` — Value that should be set on the proxied object.
