Object

net.openhft.koloboke.collect.Equivalence<T>

net.openhft.koloboke.collect.StatelessEquivalence<T>

public abstract class StatelessEquivalence<T>
extends Equivalence<T>

Base class for stateless Equivalence implementations.

StatelessEquivalence relies on the fact that your equivalence class, which extend it, don't have subclasses in turn, therefore it is strongly recommended to declare your equivalence class as final.

Override toString() if implementation is anonymous and you want to log or pretty print it, because otherwise String representation of your equivalence would be "" (empty String).

See example implementations in the documentation to identity and case insensitive equivalences.
