public class Enum2LongMap<T extends Enum<T>> extends AbstractObject2LongMap<T>
A Type Specific EnumMap implementation that allows for Primitive Values. Unlike javas implementation this one does not jump around between a single long or long array implementation based around the enum size This will cause a bit more memory usage but allows for a simpler implementation.
