Interface BytePriorityQueue

All Superinterfaces:
PriorityQueue<Byte>
All Known Implementing Classes:
AbstractBytePriorityQueue, ByteArrayFIFOQueue, ByteArrayPriorityQueue, ByteHeapPriorityQueue, BytePriorityQueues.SynchronizedPriorityQueue
public interface BytePriorityQueue extends PriorityQueue<Byte>
A type-specific PriorityQueue; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this interface strengthens comparator().
