Examples of com.google.common.base.FinalizableReferenceQueue

com.google.common.base.FinalizableReferenceQueue
A reference queue with an associated background thread that dequeues references and invokes {@link FinalizableReference#finalizeReferent()} on them.
Keep a strong reference to this object until all of the associated referents have been finalized. If this object is garbage collected earlier, the backing thread will not invoke {@code finalizeReferent()} on the remaining references. @author Bob Lee @since Guava release 02 (imported from Google Collections Library)
