类 BufferReverseIntIteratorFlyweight

java.lang.Object

org.bitlap.roaringbitmap.buffer.BufferReverseIntIteratorFlyweight

所有已实现的接口:

java.lang.Cloneable, IntIterator

public class BufferReverseIntIteratorFlyweight
extends java.lang.Object
implements IntIterator

Fast iterator minimizing the stress on the garbage collector. You can create one reusable instance of this class and then wrap(ImmutableRoaringBitmap) This iterator enumerates the stored values in reverse (starting from the end).
