I personally try to design my projects with UML, eventhough I mostly
use only a few diagrams. It helps quite a bit for documentation and
But I wouldn't want to start a big discussion about UML. Msm is
implementing only a small part of it, the state machine chapter. There
were state machines long before UML. The biggest advantage of
following the standard whenever possible is that at least there is a
standard and it is formally defined, so that you know what you get.
If your question was about where to use state machines, this would
need a longer answer. Common cases include GUI development,
implementation of communication protocols or whenever you might be
tempted to define some flags to define the state of a given class
(those who never defined a dirty flag, raise your hand ;-) ). In these
cases, state machines help you abstract away implementation details
and allow someone else understand your code more easily. I also found
them a huge help during development as thinking in terms of a model
made a problem much easier to solve.
