Class RandomIterFallbackShortNoCache

Object
RandomIterFallbackShortNoCache
All Implemented Interfaces:
RandomIter
public class RandomIterFallbackShortNoCache extends Object implements RandomIter
Modified version of ImageN RandomIterFallbackByte that stores the tile positions in a short array with less memory usage. The current tile is not cached but it is calculated every time.
