Class HashKey<T>

java.lang.Object

net.sf.mmm.util.collection.base.AbstractHashKey<T>

net.sf.mmm.util.collection.base.HashKey<T>

Type Parameters:

T - is the templated type of the delegate-object.

All Implemented Interfaces:

Serializable

public final class HashKey<T>
extends AbstractHashKey<T>

This is a simple class that allows to use any object as hash-key. It only matches the exact same instance regardless of the Object.equals(Object) method of the delegate-object. Additionally it sill matches even if the delegate-object has been modified and therefore changed its hash-code.

Since:

1.0.1
