Tech Note 2
| Excerpt |
|---|
InterProcessMutex acquire() can be used to return immediately if lock can't be acquired. |
Details
It's not obvious from the docs, but calling InterProcessMutex.acquire(0, unit) will return immediately (i.e. without any waiting) if the lock cannot be acquired.
e.g.
| Code Block |
|---|
InterProcessMutex lock = ...
boolean didLock = lock.acquire(0, TimeUnit.any);
if ( !didLock )
{
// comes back immediately
}
