Interface IMessageDispatcher

All Known Implementing Classes:

EnvelopedMessageDispatcher, FilteredMessageDispatcher, MessageDispatcher

public interface IMessageDispatcher

A message dispatcher provides the functionality to deliver a single message to a set of listeners. A message dispatcher uses a message context to access all information necessary for the message delivery. The delivery of a single message to a single listener is responsibility of the handler invocation object associated with the dispatcher. Implementations if IMessageDispatcher are partially designed using decorator pattern such that it is possible to compose different message dispatchers to achieve more complex dispatch logic.
