Class UniformEquivalenceComparator<E,C>

java.lang.Object

org.jgrapht.experimental.equivalence.UniformEquivalenceComparator<E,C>

All Implemented Interfaces:

EquivalenceComparator<E,C>

public class UniformEquivalenceComparator<E,C>
extends java.lang.Object
implements EquivalenceComparator<E,C>

This Equivalence comparator acts as if all elements are in one big global equivalence class. Useful when a comparator is needed, but there is no important difference between the elements. equivalenceCompare() always return true; equivalenceHashcode() always returns 0.
