public class Short2ObjectArrayMap<V> extends AbstractShort2ObjectMap<V> implements Short2ObjectOrderedMap<V>
A Very Specific Type Specific implementation of a ArrayMap. This type of map is for very specific use cases that usaully would have lead to Tupled Lists otherwise. It also does not allow duplication (except for array constructors) and checks from last to first. It is not designed to be used as a HashMap replacement due to the poor performance it would cause.
Note:
in this implementation SubMaps do NOT keep track of parent changes fully. For performance reasons it will just have a start/end index and not values Anything within that range will be updated appropiatly a shrink/growth of elements will break SubMaps in some ways. This can be useful but be careful, this implementation does not shrink and only grows.
