public class Byte2LongRBTreeMap extends AbstractByte2LongSortedMap implements java.io.Serializable, java.lang.Cloneable
A type-specific red-black tree map with a fast, small-footprint implementation.The iterators provided by the views of this class are type-specific bidirectional iterators. Moreover, the iterator returned by
