It's set to 0 when you have no operation and you increment it each
time you make a new one. The code looks like this (typed in mail)
[…]
if( currentOperation == currentOperationAtQueueTime )
{
[ yourClass operationDidFinish ];
currentOperation = 0;
}
Correct me if I’m wrong, but you can only set ‘currentOperation’
to zero if it’s a serial queue or you know it’s empty.
