java.lang.Object

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

public class DoublePriorityObject<O>
extends Object
implements PairInterface<Double,O>, Comparable<DoublePriorityObject<?>>

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.
