Method Details
-
finalize
protected void finalize() -
cancel
public void cancel()Description copied from class:WatchKey
This cancels the registration with the WatchService that this WatchKey was registered with. This means that no new events will be delivered to this key any more. Events that are pending can still be retreived with pollEvents(), and if the WatchKey is still marked as signalled a call to WatchService's poll() or take() functions will still return it. -
isValid
public final boolean isValid() -
pollEvents
Description copied from class:WatchKey
Returns the events that have occurred for this WatchKey. Just calling this method will not reset the signalled state of this key; you'll have to call #reset() to indicate to the WatchService that the the client is ready to receive more events and that the key can be re-queued. After the WatchService has determined that events have occurred for a registered Watchable represented by a given WatchKey, it will return that key when the client calls it's WatchService#take() or WatchService#poll() methods.- Specified by:
