CMS: get name of destination - how to ?
Hi there
I do
const cms::Destination *jmsdest = msg->getCMSReplyTo()->clone();
and now and then use the saved jmsdest, to send messages back...
many of my objects gets the same destination, so I dont want to have
hundreds
of the same destinations hanging around, instead I was to compare two
destinations, so I only has one of each.
How to do that ?
Is there a way to do dest->getname or something, so I can compare two
destinations
to see if they are indeed the same ?
sincerely,
Søren

Well don't see anything obvious other than some missing NULL checks and
not using dynamic_cast. If you can provide a complete sample or CPPUnit
test we can look into it further.
Have you tried building a release binary with debug symbols enabled so
you can get a stack trace?

const cms::Destination *d =
DestinationManager.Manage(jmsmsg->getCMSReplyTo());
from .h file
vector<const cms::Destination *> destinations;
from .cpp file
const cms::Destination *DestinationManager::Manage(
const cms::Destination *inDestination)
{
ActiveMQDestination *newmqdest = (ActiveMQDestination*)inDestination;
for (size_t x=0;x<destinations.size();x++)
{
ActiveMQDestination *oldmqdest = (ActiveMQDestination*)destinations[x];
if (newmqdest->equals(oldmqdest))
return destinations[x];
}
const cms::Destination *clone = inDestination->clone(); // clone it
destinations.push_back(clone); // and save the clone
return clone;
}

Would need to see a complete sample app to really be able to really know
what might be going wrong. Usually though in these cases it means that
something in your pointer handling isn't right and the debug build was
letting it slip by. You might want to ensure you aren't overstepping
the bounds of the array of accessing an element that should be NULL.

Weird... the 'equals' works fine in debugging mode, but when I compile for
release,
then it crashes !
ActiveMQDestination *oldmqdest = (ActiveMQDestination*)destinations[x];
if (oldmqdest->equals(newmqdest)) CRASH
help,
Søren

You could cast them to ActiveMQDestination pointers and call the equals
method on one, passing in the target pointer.
