Examples of FSMDirector

ptolemy.domains.fsm.kernel.FSMDirector
An FSMDirector governs the execution of a modal model. A modal model is a TypedCompositeActor with a FSMDirector as local director. The mode control logic is captured by a mode controller, an instance of FSMActor contained by the composite actor. Each state of the mode controller represents a mode of operation and can be refined by an opaque CompositeActor contained by the same composite actor.
When a modal model is fired, this director first transfers the input tokens from the outside domain to the mode controller and the refinement of its current state. The preemptive transitions from the current state of the mode controller are examined. If there is more than one transition enabled, and any of the enabled transitions is not marked nondeterministic, an exception is thrown. If there is exactly one preemptive transition enabled then it is chosen. The choice actions (outputActions) contained by the transition are executed. Any output token produced by the mode controller is transferred to both the output ports of the modal model and the input ports of the mode controller. Then the refinements associated with the enabled transition are executed. Any output token produced by the refinements is transferred to both the output ports of the modal model and the input ports of the mode controller. The refinements of the current state will not be fired.
If no preemptive transition is enabled, the refinements of the current state are fired. Any output token produced by the refinements is transferred to both the output ports of the modal model and the input ports of the mode controller. After this, the non-preemptive transitions from the current state of the mode controller are examined. If there is more than one transition enabled, and any of the enabled transitions is not marked nondeterministic, an exception is thrown. If there is exactly one non-preemptive transition enabled then it is chosen and the choice actions contained by the transition are executed. Any output token produced by the mode controller is transferred to the output ports of the modal model and the input ports of the mode controller. Then, the refinements of the enabled transition are executed. Any output token produced by the refinements is transferred to both the output ports of the modal model and the input ports of the mode controller.
At the end of one firing, the modal model transfers its outputs to the outside model. The mode controller does not change state during successive firings in one iteration of the top level in order to support upper level domains that iterate to a fixed point.
When the modal model is postfired, the chosen transition of the latest firing is committed. The commit actions contained by the transition are executed and the current state of the mode controller is set to the destination state of the transition. @author Xiaojun Liu, Haiyang Zheng @version $Id: FSMDirector.java,v 1.141 2007/12/07 06:27:39 cxh Exp $ @since Ptolemy II 0.4 @Pt.ProposedRating Yellow (hyzheng) @Pt.AcceptedRating Red (hyzheng) @see FSMActor

        // (because the director class matches the default).
        // Issuing a change request during construction is
        // problematic because it causes the Vergil library
        // to close when you first open a sublibrary containing
        // an instance of ModalModel.
        FSMDirector defaultFSMDirector = new FSMDirector(this, "_Director");
        defaultFSMDirector.controllerName.setExpression("_Controller");


        // NOTE: If there is a container for this ModalModel, and it
        // has a director, then we get the default value from that
        // director, and also get a list of suggested values.
