Examples of org.datanucleus.util.WeakValueMap

org.datanucleus.util.WeakValueMap
A java.util.Map implementation using weak reference values.
The values are stored in the map as weak references. If the garbage collector clears the reference, the corresponding key is automatically removed from the map. @see WeakReference
