Method Detail

acquire

public void acquire()

Acquire the mutex. The mutex can be acquired multiple times by the same thread, provided that it is released as many times as it is acquired. The calling thread blocks until it has acquired the mutex. (There is no timeout).

tryToAcquire

public boolean tryToAcquire()

Attempts to acquire the mutex. Returns false (and does not block) if it can't get it.

release

public void release()

Release the mutex. The mutex has to be released as many times as it was acquired to actually unlock the resource. The mutex must be released by the thread that acquired it

Throws:

IllegalStateException - (a RuntimeException) if a thread other than the current owner tries to release the mutex.
