Class RequestQueue

  org.apache.manifoldcf.authorities.system.RequestQueue

public class RequestQueue
extends java.lang.Object

This class describes a authorization request queue, which has a "stuffer" servlet and many "reader" threads. The queue manages thread synchronization so that (a) the "stuffer" servlet blindly appends authority requests, and then waits for these requests to be completed, and (b) the "reader" threads block if queue is empty. The objects being queued are all AuthRequest objects.
