Class WeakReference

java.lang.Object
java.lang.ref.Reference
java.lang.ref.WeakReference

public class WeakReference extends Reference
This class provides support for weak references. Weak references are most often used to implement canonicalizing mappings. Suppose that the garbage collector determines at a certain point in time that an object is weakly reachable. At that time it will atomically clear all the weak references to that object and all weak references to any other weakly- reachable objects from which that object is reachable through a chain of strong and weak references. Since: JDK1.2, CLDC 1.1
