      org.apache.cocoon.components.thread.SynchronousChannel

All Implemented Interfaces:

EDU.oswego.cs.dl.util.concurrent.BoundedChannel, EDU.oswego.cs.dl.util.concurrent.Channel, EDU.oswego.cs.dl.util.concurrent.Puttable, EDU.oswego.cs.dl.util.concurrent.Takable, Queue

public class SynchronousChannel
extends EDU.oswego.cs.dl.util.concurrent.SynchronousChannel
implements Queue

A rendezvous channel, similar to those used in CSP and Ada. Each put must wait for a take, and vice versa. Synchronous channels are well suited for handoff designs, in which an object running in one thread must synch up with an object running in another thread in order to hand it some information, event, or task.

If you only need threads to synch up without exchanging information, consider using a Barrier. If you need bidirectional exchanges, consider using a Rendezvous.
