java.lang.Objectorg.springframework.integration.dispatcher.AbstractDispatcher
public abstract class AbstractDispatcher
Base class for MessageDispatcher
implementations.
The subclasses implement the actual dispatching strategy, but this base class
manages the registration of MessageHandler
s. Although the implemented
dispatching strategies may invoke handles in different ways (e.g. round-robin
vs. failover), this class does maintain the order of the underlying
collection. See the OrderedAwareCopyOnWriteArraySet
for more detail.
