GenericObjectPool: Add a getNumWaiters() method for monitoring purposes
-----------------------------------------------------------------------
Key: POOL-159
URL: https://issues.apache.org/jira/browse/POOL-159
Project: Commons Pool
Issue Type: Improvement
Affects Versions: 1.5.4
Reporter: Mike Muller
I would like to be able to determine the number of threads waiting to obtain an
object from the pool for monitoring purposes. This would be most applicable
when the WHEN_EXHAUSTED_BLOCK option is used. I propose the following method:
/**
* Return the number of threads currently waiting for an object from this
pool.
*
* @return the number of threads currently waiting for an object from this
pool
*/
public synchronized int getNumWaiters() {
return _allocateQueue.size();
}
