Package Summary Overview Summary

### class:PhantomReference [NONE]
public non-sealed class PhantomReference<T>extends Reference<T> Phantom reference objects, which are enqueued after the collector determines that their referents may otherwise be reclaimed. Phantom references are most often used to schedule post-mortem cleanup actions. Suppose the garbage collector determines at a certain point in time that an object is phantom reachable . At that time it will atomically clear all phantom references to that object and all phantom references to any other phantom-reachable objects from which that object is reachable. At the same time or at some later time it will enqueue those newly-cleared phantom references that are registered with reference queues. In order to ensure that a reclaimable object remains so, the referent of a phantom reference may not be retrieved: The `get` method of a phantom reference always returns `null`. The `refersTo` method can be used to test whether some object is the referent of a phantom reference. Since: 1.2

### method:get() [NONE]
### get public T get() Returns this reference object's referent. Because the referent of a phantom reference is always inaccessible, this method always returns `null`. Overrides: `get` in class `Reference<T>` Returns: `null` See Also: `Reference.refersTo(T)`
