public class PrimitiveLongStack
extends Object

Like a Stack<Long> but for primitive longs. Virtually GC free in that it has an long[] and merely moves a cursor where to push(long) and poll() values to and from. If many items goes in the stack the long[] will grow to accomodate all of them, but not shrink again.
