Thomas Neidhart commented on COLLECTIONS-432:
---------------------------------------------
Removed Buffer interface from ArrayStack in r1468579.
Unfortunately, the Queue interface can not be implemented for ArrayStack as the
signatures for peek/pop are conflicting.
> Replace Buffer interface with java.util.Queue

> Since jdk 1.5, a new interface Queue is available which is basically
> identical to the Buffer interface of CC.
> Some of our implementations already have a counterpart in the jdk:
> * BoundedFifoBuffer -> LinkedBlockingQueue or ArrayBlockingQueue
> * UnboundedFifoBuffer -> LinkedList or ArrayDeque
> * PriorityBuffer -> PriorityQueue
> Thus the Buffer queue shall be replaced by the existing Queue, unneeded
> implementations be removed and the rest adapted.
