Subject [jira] [Commented] (AMQCPP-405) CMS sender thread hangs after restarting broker
Date Sat, 29 Sep 2012 18:04:07 GMT


Timothy Bish commented on AMQCPP-405:

The code actually returns a reference to a Collection<E> type so you can either create
a reference or assign the return value to a concrete type link LinkedList<E> or ArrayList<E>
depending on what you plan to do with the result.  You can take a look at the unit tests for
the StlMap and HashMap classes.  This change allow the returned value to simply be a reference
to some internal proxy object that doesn't require copying everything in the Map's values
or keys so its much more efficient.  You code code look as follows:


Collection<std::string>& values = someMap.values();
