public class Object2FloatOpenHashMap<T> extends AbstractObject2FloatMap<T> implements ITrimmable
A Type Specific Custom implementation of the HashMap Instead of using Wrapper Object Arrays for storing keys and values there is dedicated arrays for storing keys and values. Extra to that there is a couple quality of life functions provided
