Constructor Summary public   FileLockImpl(FileChannel channel, long position, long size, boolean shared)      Answers a new file lock object with the given parameters. Method Summary public  boolean isValid()      Tests to see if the lock is valid. public  void release()      Releases the file lock on the channel that acquired it. Constructor Detail FileLockImpl public FileLockImpl(FileChannel channel, long position, long size, boolean shared)(Code) Answers a new file lock object with the given parameters. Parameters:   channel - the file channel hosting the lock. Parameters:   position - the start position of the lock, in bytes Parameters:   size - the length of the lock, in bytes Parameters:   shared - whether this lock is shared (true) or exclusive (false) Method Detail isValid public boolean isValid()(Code) Tests to see if the lock is valid. A lock can be invalidated if the channel it is acquired on is closed or if it is released. (non-Javadoc) See Also:   java.nio.channels.FileLock.isValid release public void release() throws IOException(Code) Releases the file lock on the channel that acquired it. Releasing an invalid lock has no effect.
