Initialize and start statecharts

Edit online

IBM® Engineering Systems Design Rhapsody® generates two operations to initialize statecharts and start reactive behavior:

  • initStatechart()
  • startBehavior()

Initializing statecharts

The initStatechart() operation initializes the statechart for a reactive object. For example, the following initStatechart() operation, generated in the implementation file for HomeHeatingSystem, initializes the statechart for HomeHeatingSystem:
static void initStatechart(HomeHeatingSystem* const me) {
              me->rootState_subState = HomeHeatingSystem_RiCNonState;
              me->rootState_active = HomeHeatingSystem_RiCNonState;
         }
This routine initializes the rootState_subState and rootState_active pointers for the HomeHeatingSystem object to <object>_RiCNonState (the default state is 0) when the object is created.

Starting reactive behavior

The startBehavior() operation starts the behavior of reactive objects:

  • The <package>_startBehavior() operation starts the behavior of the reactive objects in a package.
  • The <object>_startBehavior() operation starts the behavior of an individual object.

Note that startBehavior() is not to be called from within the constructor.
