Memory that does not exist in reality.Phantom references are most often used for scheduling pre-mortem cleanup actions in a more flexible way than is possible with the java finalization mechanism. Unlike soft and weak references, phantom references are not automatically cleared by the garbage collector as they are enqueued. |
