ObjectArrayPriorityQueue (Primitive-Collections 0.7.0 API)

java.lang.Object
- speiger.src.collections.objects.queues.AbstractObjectPriorityQueue<T>
- - speiger.src.collections.objects.queues.ObjectArrayPriorityQueue<T>

Type Parameters:

T - the type of elements maintained by this Collection

All Implemented Interfaces:

java.lang.Iterable<T>, ObjectIterable<T>, ObjectPriorityQueue<T>
```
public class ObjectArrayPriorityQueue<T>
extends AbstractObjectPriorityQueue<T>
```
A Array Priority Queue, this is a very unoptimized implementation of the PriorityQueue for very specific usecases. It allows for duplicated entries and works like List.indexOf(Object) search. It is highly suggested to use HeapPriorityQueue otherwise, unless you know why you need this specific implementation
