Method Detail

lock

void lock()
   throws java.io.IOException

Acquires the lock, blocking to wait until the lock can be acquired.

If the thread executing this method is interrupted, this method will throw a runtime exception.

Throws:

java.io.IOException

tryLock

boolean tryLock(long timeout,
                @NonNull
                java.util.concurrent.TimeUnit timeUnit)
         throws java.io.IOException

Tries acquiring the lock, blocking to wait until the lock can be acquired or the specified time has passed, then returns true in the first case and false in the second case.

If the thread executing this method is interrupted, this method will throw a runtime exception.

This method will try acquiring the lock first before checking for timeout. A non-positive timeout means the method will return immediately after the first try. This behavior is similar to a ReentrantReadWriteLock.

Parameters:

timeout - the maximum time to wait for the lock

timeUnit - the unit of the timeout

Returns:

true if the lock was acquired

Throws:

java.io.IOException

unlock

void unlock()
     throws java.io.IOException

Releases the lock. This method does not block.

Throws:

java.io.IOException
