Notations (Using Stateflow)

Using Stateflow

User-Written Functions

You can specify calls to user-written functions in the action language. These guidelines apply to user-written function calls:

Define a function by its name, any arguments in parenthesis, and an optional semicolon.
String parameters to user-written functions are passed between single quotes. For example, func(`string').
You can nest function calls.

Example: Function Call Transition Action

These are example formats of function calls using transition action notation.

If S1 is active, event e occurs, c is true, and the transition destination is determined, then a function call is made to function_name with arg1, arg2, and arg3. The transition action in the transition from S2 to S3 shows a function call nested within another function call.

Example: Function Call State Action

These are example formats of function calls using state action notation.

When the default transition into S1 occurs, S1 is marked active and then its entry action, a function call to function_name1 with the specified arguments, is executed and completed. If S2 is active and an event occurs, the during action, a function call to function_name3 with the specified arguments, executes and completes.
