Class AStarHeap<NODE>

java.lang.Object

cz.cuni.amis.utils.astar.AStarHeap<NODE>

All Implemented Interfaces:

Iterable<NODE>, Collection<NODE>

public class AStarHeap<NODE>
extends Object
implements Collection<NODE>

This is Heap used by AStar algorithm. Note that we assume that inserted Object has correctly implemented hashCode() and equals() function!
