Class ObjRefUtils

java.lang.Object
  java.lang.Thread
      org.lateralnz.common.util.ObjRefUtils

All Implemented Interfaces:

java.lang.Runnable

public final class ObjRefUtils
extends java.lang.Thread

a way to ensure that certain singletons and other objects which should not be garbage collected, are not. This runs as a sleeping thread, and stores objects in a list -- they can never be retrieved since this should not be used as a retrieval mechanism
