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 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 soft references. At the same time it will declare all of the formerly weakly-reachable objects to be finalizable. At the same time or at some later time it will enqueue those newly-cleared weak references that are registered with reference queues.

object the new weak reference will refer to referent)Creates a new weak reference that refers to the given object. |
| public | WeakReference(T
object the new weak reference will refer to referent, ReferenceQueue<? super T> the queue with which the reference is to be registered,
or q)null if registration is not requiredCreates a new weak reference that refers to the given object and is registered with the given queue. |
| WeakReference | back to summary |
|---|---|
| public WeakReference(T referent) Creates a new weak reference that refers to the given object. The new reference is not registered with any queue.
