Examples of com.sleepycat.je.utilint.BitMap

com.sleepycat.je.utilint.BitMap
Bitmap which supports indexing with long arguments. java.util.BitSet provides all the functionality and performance we need, but requires integer indexing. Long indexing is implemented by keeping a Map of java.util.BitSets, where each bitset covers 2^16 bits worth of values. The Bitmap may be sparse, in that each segment is only instantiated when needed. Note that this class is currently not thread safe; adding a new bitset segment is not protected.
