Transitions | SMACC – State Machine Asynchronous C++

In 2003, David Abrams, founder of the Boost Libraries, Author of boost.mpl and Aleksey Gurtovoy, wrote an example for their MPL library that encompassed a state machine (procedural) and the first Transition Table. Seen below…

This table, was extremely popular and was adopted almost unchanged into other state machine libraries such as boost.MSM.

In the boost.MPL library, only procedural state machines could be written, and the transition table was for the entire state machine.

In SMACC we’ve adapted the Transition Table to the behavioral state machine (along with Boost Statechart) by including a transition table inside of every state.
