Class GenericPriorityQueue

java.lang.Object
  net.sf.zig_project.gpl.common.queue.PriorityQueueBase
      net.sf.zig_project.gpl.common.queue.GenericPriorityQueue

All Implemented Interfaces:

OrderedBlockingQueue, Queue

Direct Known Subclasses:

PriorityQueue

public abstract class GenericPriorityQueue

extends PriorityQueueBase

Priority Queue supporting generic elements. The only additional requirement for adding an object is the priority at which to queue it. When using a GenericPriorityQueue, once constructed, only the PriorityQueue should be used to manage the underlying queues. In future releases, updating the contents of one of the underlying queues without using the methods provided by GenericPriorityQueue may result in surprising results.
