## Class PriorityQueueAbstract<E>

- java.lang.Object
- - tigase.util.PriorityQueueAbstract<E>

- Type Parameters:
    `E` -
  Direct Known Subclasses:
    NonpriorityQueue, PriorityQueueRelaxed, PriorityQueueStrict

      public abstract class PriorityQueueAbstract<E>
      extends Object

  Works like a LinkedBlockingQueue using the put() and take() methods but with an additional priority integer parameter. The elemnt returned from take() will honor the priority in such a way that all elements of a lower priority will be returned before any elemens of a higher priority.
