ObjectProxy  - AS3 Flex

A reference to the EventDispatcher for this proxy.

A hashmap of property change notifiers that this proxy is listening for changes from; the key of the map is the property name.

The object being proxied.

Contains a list of all of the property names for the proxied object. Descendants need to fill this list by overriding the setupPropertyList() method.

Indicates what kind of proxy to create when proxying complex properties. Subclasses should assign this value appropriately.

The qualified type name associated with this object.

The unique identifier for this object.

Initializes this proxy with the specified object, id and proxy depth.

Registers an event listener object so that the listener receives notification of an event. For more information, including descriptions of the parameters see addEventListener() in the flash.events.EventDispatcher class.

Parametreler

İlgili API Öğeleri

Returns the value of the proxied object's method with the specified name.

Parametreler

Deletes the specified property on the proxied object and sends notification of the delete to the handler.

Parametreler

Dispatches an event into the event flow. For more information, see the flash.events.EventDispatcher class.

Parametreler

İlgili API Öğeleri

Provides a place for subclasses to override how a complex property that needs to be either proxied or daisy chained for event bubbling is managed.

Parametreler

Returns the specified property value of the proxied object.

Parametreler

Checks whether there are any event listeners registered for a specific type of event. This allows you to determine where an object has altered handling of an event type in the event flow hierarchy. For more information, see the flash.events.EventDispatcher class.

Parametreler

İlgili API Öğeleri

Called when a complex property is updated.

Parametreler

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. You can then set the object_proxy object property to this value.

Parametreler

Removes an event listener. If there is no matching listener registered with the EventDispatcher object, a call to this method has no effect. For more information, see the flash.events.EventDispatcher class.

Parametreler

İlgili API Öğeleri

Updates the specified property on the proxied object and sends notification of the update to the handler.

Parametreler

This method creates an array of all of the property names for the proxied object. Descendants must override this method if they wish to add more properties to this list. Be sure to call super.setupPropertyList before making any changes to the propertyList property.

Checks whether an event listener is registered with this object or any of its ancestors for the specified event type. This method returns true if an event listener is triggered during any phase of the event flow when an event of the specified type is dispatched to this object or any of its descendants. For more information, see the flash.events.EventDispatcher class.

İlgili API Öğeleri

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.
