A crash course in UML state machines

Sun, 03/01/2009 - 07:00
In this article series. Miro Samek introduces you to the basics of UML state machines basic notation, clarifying semantics, and provides some code examples to the role of UML state machines have in practical, everyday programming rather than mathematical abstractions. Up first: The over simplification of the event-action paradigm.
