Class Enum2DoubleMap<T extends java.lang.Enum<T>>

java.lang.Object

java.util.AbstractMap<T,java.lang.Double>

speiger.src.collections.objects.maps.abstracts.AbstractObject2DoubleMap<T>

speiger.src.collections.objects.maps.impl.misc.Enum2DoubleMap<T>

Type Parameters:

T - the type of elements maintained by this Collection

All Implemented Interfaces:

java.util.function.ToDoubleFunction<T>, java.util.Map<T,java.lang.Double>, Object2DoubleFunction<T>, Object2DoubleMap<T>

Direct Known Subclasses:

LinkedEnum2DoubleMap

public class Enum2DoubleMap<T extends java.lang.Enum<T>>
extends AbstractObject2DoubleMap<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.
