Class TMMFMessageDestination

class TMMFMessageDestination;

Description

Describes the destination of a message in the controller framework.

The destination is defined by a UID describing the interface and an integer object handle. The controller framework uses this information when it receives a message to decide where to send the message.

The controller plugin and controller proxy use the special constant handles KMMFObjectHandleControllerProxy and KMMFObjectHandleController for efficiency.
