org.jgroups.blocks.MessageDispatcher

Provides synchronous and asynchronous message sending with request-response correlation; i.e., matching responses with the original request. It also offers push-style message reception (by internally using the PullPushAdapter).

Channels are simple patterns to asynchronously send a receive messages. However, a significant number of communication patterns in group communication require synchronous communication. For example, a sender would like to send a message to the group and wait for all responses. Or another application would like to send a message to the group and wait only until the majority of the receivers have sent a response, or until a timeout occurred. MessageDispatcher offers a combination of the above pattern with other patterns.

Used on top of channel to implement group requests. Client's handle() method is called when request is received. Is the equivalent of RpcProtocol on the application instead of protocol level. @author Bela Ban
