java.lang.Object

edu.illinois.cs.cogcomp.core.datastructures.IntPair

All Implemented Interfaces:

Serializable

public class IntPair
extends Object
implements Serializable

This utility class represents a pair of integers. This is faster than using Pair<Integer, Integer> because it does not do boxing and unboxing. This class implements equals and hashcode and can be used as keys to maps.
