class Puppet::Util::Queue::Stomp

Implements the Ruby Stomp client as a queue type within the Puppet::Indirector::Queue::Client registry, for use with the :queue indirection terminus type.

Looks to Puppet[:queue_source] for the sole argument to the underlying Stomp::Client constructor; consequently, for this client to work, Puppet[:queue_source] must use the Stomp::Client URL-like syntax for identifying the Stomp message broker: login:pass@host.port
