Method Details

register

public static void register(Object object,
 Runnable cleanupTask)

Register the given Object for which the Runnable will be executed once there are no references to the object anymore. This should only be used if there are no other ways to execute some cleanup once the Object is not reachable anymore because it is not a cheap way to handle the cleanup.
