Changes for version 0.10 - 2004-12-17

  • Moved state-specific methods to new FSA::State class. This is a pretty significant change and can introduce backwards compatability issues, so the version has been bumped up to 0.10.
  • FSA::State objects are now passed to state actions, rather than the FSA::Rules object. Call their machine() method to get the FSA::Rules object.
  • Switch actions are now passed two arguments: The current FSA::State object and the FSA::State object for the new state.
  • Added notes() method for storing arbitrary notes in the FSA::Rules object.
  • Added states() method to return one or more of the state objects in a machine.
  • Moved the "message" and "result" methods to the state class. The "set_" forms are gone now, since you don't need to specify a state when you have a state. Added last_message() and last_result() methods to FSA::Rules to get the most recent messages and results from the states.
  • Added convenience methods prev_state(), notes(), and done() to the state class to reach back into the FSA::Rules object.
  • The start() method will now throw an exception if the machine is already running. Call reset() before calling start on a running machine.
  • Added "strict" attribute to prevent rules from short-circuiting and cause an exception to be thrown if more than one rule returns a true value during a call to try_switch(). Suggested by Curtis Poe.
  • Added optional parameter hash reference as first argument to new(). It can force the machine to be started before being returned, or can set the "done" or "strict" attributes.
