Thread Monitor

[James X Williams]

Friends:
Does the thread lose the monitor on sleep, yield or block. I feel it does not.
Can some one confirm this.

sleep() and yield() doesnot release the lock on the object.
I'm not sure abt block.

[Jim Yingst]

Not on block either. The only ways I remember that a lock on a monitor is given up are: (1) when the synchronized method or block ends, and (2) when the monitor's wait() method is called (it's then re-acquired after notify() in order for the thread to resume in synchronized code).

A thread gets blocked
- by calling sleep(x);
- by calling suspend() (deprecated);
- by calling wait();
- due to I/O block
- while waiting for an object lock or "monitor"
The thread which has acquired the lock and is in critical section
would not give up the lock when it calls sleep(), suspend() or
when its blocking for i/o.
The thread would give up the lock when the object it is locking
on calls wait(),
SO I think you are correct.
sleep() and yield() are Thread methods and blocking is
a consequence of an operation. So they cannot influence
the lock acquired by an Object.
