MessagingAPI.CompositeMessageReceiver Class Reference
Detailed Description
A CompositeMessageReceiver is a message receiver that can have children that will themselves receive messages.
The children should be MessageReceiver instances, although for backwards compatibility we currently allow the children to implement parts of the interface or to simply define the appropriate message handlers.
