Constructor Detail

FSMDirector

public FSMDirector(FSMDirector director)

Construct the code generator helper associated with the given FSMDirector.

Parameters:

director - The associated ptolemy.domains.modal.kernel.FSMDirector

Method Detail

generateFireCode

public java.lang.String generateFireCode()
                                  throws IllegalActionException

Generate the code for the firing of actors controlled by this director. It generates code for making preemptive transition, checking if a transition is taken, firing refinements and making non-preemptive transition.

Specified by:

generateFireCode in interface ActorCodeGenerator

Overrides:

generateFireCode in class Director

Returns:

The generated fire code.

Throws:

IllegalActionException - If the helper associated with an actor throws it while generating fire code for the actor.

_generateRefinementCode

protected void _generateRefinementCode(java.lang.StringBuffer code)
                                throws IllegalActionException

Generate code for the firing of refinements.

Parameters:

code - The string buffer that the generated code is appended to.

Throws:

IllegalActionException - If the helper associated with an actor throws it while generating fire code for the actor.

generateFireFunctionCode

public java.lang.String generateFireFunctionCode()
                                          throws IllegalActionException

Generate The fire function code. This method is called when the firing code of each actor is not inlined. Each actor's firing code is in a function with the same name as that of the actor.

Specified by:

generateFireFunctionCode in interface ActorCodeGenerator

Overrides:

generateFireFunctionCode in class Director

Returns:

The fire function code.

Throws:

IllegalActionException - If thrown while generating fire code.
