Forbidden Operators

Description#

Specific predefined SCADE operators shall not be used: merge (45) and When (28). parameter: comma separated list of operator IDs, for example.: 45,28

The rule parameter is a comma-separated string containing predefined operator identifiers. Available identifiers are documented in the SCADE Python API guide, under section Access to Predefined Operators in Python. Default parameter value is 45, 28 (Merge, When).

Rationale#

This enforces compliance with a specific modeling standard by ensuring that a given list of predefined operators is avoided in diagrams.

The default value of the rule parameter prevents use of the Merge and When operators, that are not intended for direct use and are hidden from toolbars by default in the SCADE editor.

Note: this is a stronger version of rule Disadvised Operators: its severity is REQUIRED.

Verification#

This rule checks all operator calls in a model and fails if one of the operators in the parameter list is called.

Resolution#

Modify the offending operator calls as detailed in the rule failure message.

Customization#

N/A.
