Number of operator calls in conditions

Number of operator calls in conditions

Description

Number of logical/comparison operator calls within conditions at Transitions or IfNodes. Number and Exceptions given as parameters: ‘calls=number,exc=op1;op2;etc.’

Default parameter value is 4 maximum calls, with array access excluded from call limit calculations.

Rationale

This enforces compliance with a specific modeling standard by defining a maximum number of possible comparisons inside If Nodes and state machine transitions.

Verification

This rule checks all If Node conditions inside of If Blocks, and every transition condition inside state machines.

For each one, it recursively counts the uses of comparison predefined operators: array access, AND, OR, XOR, NOT, #, <, <=, >, >=, =, <>. Any of the operators may be excluded from the count by using the parameter.

The rule fails if any condition has a count greater than the call limit.

Resolution

Modify the offending condition to reduce the number of comparison operator calls.
