Hi all!
Guys, I have a task to discover all SNMP devices in some IP range. I'm going
to use asynchronous message sending by means of something like this:
// iterating through IPs, ports, communities...
for (...)
{
snmp.send(pdu, target, transportMapping, null, new
ResponseListener()
{
public void onResponse(ResponseEvent event)
{
// my code to write results
}
});
}
Then I need to get know when all requests are processed. Now the only way to
check this I see is to use counter in all listener invocations to check
condition like
while (counter < totalSent)
{
Thread.sleep(1000);
}
This way works fine while Snmp4J engine is not interrupted (for example, by
RuntimeException thrown by ResponseListener) and listeners are actually
called. It's not rather reliable for me.
Another aproach I see is:
1. Extend current CommonTimer interface to provide number of scheduled not
yet executed tasks
2. Create getTimer() method for Snmp class or change modifier of Snmp#timer
field to protected
Your ideas are very appreciated.
Nikita.
