Examples of java.util.IdentityHashMap.containsValue()

java.util.IdentityHashMap.containsValue()
Tests whether the specified object reference is a value in this identity hash map. @param value value whose presence in this map is to be tested @return true if this map maps one or more keys to thespecified object reference @see #containsKey(Object)
