Class BufferReverseIntIteratorFlyweight

java.lang.Object
org.roaringbitmap.buffer.BufferReverseIntIteratorFlyweight
All Implemented Interfaces:
Cloneable, IntIterator
public class BufferReverseIntIteratorFlyweight extends 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).

  • Constructor Details

    • BufferReverseIntIteratorFlyweight

      public BufferReverseIntIteratorFlyweight()
      Creates an instance that is not ready for iteration. You must first call wrap(ImmutableRoaringBitmap).

      public BufferReverseIntIteratorFlyweight​(ImmutableRoaringBitmap r)
      Creates an instance that is ready for iteration.
      Parameters:
      r - bitmap to be iterated over
