Constructor Detail

JDKDirectoryWatch

public JDKDirectoryWatch(Path directory,
                         Executor exec,
                         BiConsumer<EventHandlingWatch,WatchEvent> eventHandler,
                         Predicate<WatchEvent> eventFilter)

JDKDirectoryWatch

public JDKDirectoryWatch(Path directory,
                         Executor exec,
                         BiConsumer<EventHandlingWatch,WatchEvent> eventHandler,
                         Predicate<WatchEvent> eventFilter,
                         boolean nativeRecursive)

Method Detail

isClosed

public boolean isClosed()

getScope

public WatchScope getScope()

Description copied from interface: ActiveWatch

Gets the scope of this watch.

handleEvent

public void handleEvent(WatchEvent e)

Description copied from interface: EventHandlingWatch

Handles `event`. The purpose of this method is to trigger the event handler of this watch "from the outside" (in addition to having native file system libraries trigger the event handler "from the inside"). This is useful to report synthetic events (e.g., while handling overflows).

Specified by:

handleEvent in interface EventHandlingWatch

Overrides:

handleEvent in class JDKBaseWatch

close

public void close()
           throws IOException

Throws:

IOException

start

protected void start()
              throws IOException

Description copied from class: JDKBaseWatch

Starts this watch.

Specified by:

start in class JDKBaseWatch

Throws:

IOException - When an I/O exception of some sort has occurred (e.g., a nested watch failed to start)
