Class IntegerPriorityObject<O>

java.lang.Object

de.lmu.ifi.dbs.elki.utilities.datastructures.heap.IntegerPriorityObject<O>

Type Parameters:

O - Stored object type.

All Implemented Interfaces:

PairInterface<Integer,O>, Comparable<IntegerPriorityObject<?>>

public class IntegerPriorityObject<O>
extends Object
implements PairInterface<Integer,O>, Comparable<IntegerPriorityObject<?>>

Object for a priority queue with integer priority. Can be used in the UpdatableHeap, since hashcode and equality use the stored objects only, not the priority.
