I'm actually implementing some code in a publishfilter plugin that
tries to do certains things if the message is a publish message (and
other things if it is a subscribe). This is why I'm using
MsgUnit.getKeyData().

I really need a finer granularity (either it is definitly a publish or
definitely a subscribe). Either a getType implementation or
.isSubscribe and .isPublish would be fine.
