abstractpublic class FinalizableWeakReference extends WeakReference implements FinalizableReference(Code)
Weak reference with a
FinalizableReference.finalizeReferent method
which a background thread invokes after the garbage collector reclaims the
referent. This is a simpler alternative to using a
java.lang.ref.ReferenceQueue .
