Class FIFOMessageQueue<K,V>

java.lang.Object

org.jgroups.util.FIFOMessageQueue<K,V>

public class FIFOMessageQueue<K,V>
extends java.lang.Object

Blocking queue which can only process 1 message per service concurrently, establishing FIFO order per sender. Example: if message A1, A2, A3, B1, B2 (where A and B are service names for services on top of a Multiplexer) arrive at the same time, then this class will deliver A1 and B1 concurrently (ie. pass them up to the thread pool for processing). Only when A1 is done will A2 be processed, same for B2: it will get processed when B1 is done. Thus, messages for different services are processed concurrently; messages from the same service are processed FIFO.
