All Implemented Interfaces:

FinalizableReference

public abstract class FinalizablePhantomReference<T>
extends java.lang.ref.PhantomReference<T>
implements FinalizableReference

Phantom reference with a finalizeReferent() method which a background thread invokes after the garbage collector reclaims the referent. This is a simpler alternative to using a ReferenceQueue.

Unlike a normal phantom reference, this reference will be cleared automatically.
