Object2IntOpenHashMap (Primitive-Collections 0.2.0 API)

java.lang.Object
- java.util.AbstractMap<T,java.lang.Integer>
- - speiger.src.collections.objects.maps.abstracts.AbstractObject2IntMap<T>
  - - speiger.src.collections.objects.maps.impl.hash.Object2IntOpenHashMap<T>

Type Parameters:

T - the type of elements maintained by this Collection

All Implemented Interfaces:

java.util.function.ToIntFunction<T>, java.util.Map<T,java.lang.Integer>, Object2IntFunction<T>, Object2IntMap<T>

Direct Known Subclasses:

Object2IntLinkedOpenHashMap
```
public class Object2IntOpenHashMap<T>
extends AbstractObject2IntMap<T>
```
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
