Class CleanerReferencer

java.lang.Object
  java.lang.ref.Reference<T>
      java.lang.ref.WeakReference<Cleaner>
          org.ow2.util.pool.impl.enhanced.internal.thread.impl.CleanerReferencer

All Implemented Interfaces:

java.lang.Runnable

public final class CleanerReferencer
extends java.lang.ref.WeakReference<Cleaner>
implements java.lang.Runnable

Keep a reference on cleaner. If cleaner does not have anything to clean then we keep only a weak reference on cleaner. So if cleaner is not used anywhere else, the cleaner is garbage collected. It produce the end of the thread running this object. And normally this object should be also garbage collected. Warning : if you do not call add after creating a weak reference which use queue of cleaner, then the thread running keeper could be terminated whereas cleaner is not garbage collected. The cleaner will not continue to work but no error will occurs. This class is final because its constructor starts a thread on its instances.
