Tutorials

  • ../Tutorials/Templating - SCXML allows for defining of a certain FSM externally which can be re-used for convenience. This tutorial briefly covers the use-cases and the implementation of the Templating Pattern.

  • ../Tutorials/History - Remembering State Information - This tutorial describes the uses of <history/> element in SCXML. The history is used when it is required to remember the state of a complex state. i.e. If it were required to enter a complex state at the same point where we left it, we would use a history element to ensure that the state is preserved when the complex state is exited

  • ../Tutorials/Logging - SCXML uses commons-logging, a wrapper that works between others with Log4J ...

  • ../Tutorials/ImplicitEvents - Implicit events supported by Commons SCXML (.entry and .exit for states and .change for data)
