| The second station for an outgoing message is a SendQueue. In theory a
given Message Transport subsystem can have multiple SendQueues.
For this release we only make one, instantiated as a SendQueueImpl.
Either way, the SendQueues are instantiated by a SendQueueFactory,
accessible to SendLinkImpl as the internal MTS service
SendQueue.
The sendMessage method is used to queue messages
in preparation for passing them onto the next station, a Router.
Ordinarily this would only be called from a SendLinkImpl. The
processing of queued messages is assumed to take place in its own
thread, not the caller's thread. In other words, sendMessage is
the final call in the original client's call sequence.
In a system with multiple SendQueues, the matches
method would be used by the SendQueueFactory to avoid making any
particular queue more than once.
The previous stop is SendLink. The next stop is Router.
