Hi Matthieu, I'm trying to understand some existing S4 code. So, that means, by calling the close() method, the PE instances are still alive, just that the resources that allocated to the instances are freed up. Are my statements correct?
What are the normal use case for this close method to be invoked? And, what is "poison" event? regards, Arinto www.otnira.com On Sun, May 5, 2013 at 2:48 PM, Matthieu Morel <matth...@yahoo-inc.com>wrote: > Hi Arinto, > > that method is for properly cleaning up a PE instance.
