Maximum call graph depth

Maximum call graph depth

Description

Maximum depth of the call graph shall not exceed ‘parameter’. Check is performed on only public or all operators. Parameter: depth=:maximum value, visibility=Public,ALL (e.g.: depth=7,visibility=Public)

Rationale

This enforces compliance with a specific modeling standard by placing an upper bound on how many operator calls may be nested.

Verification

This rule checks all model operators. Depending on parameter visibility, it may skip non-public operators.

For each checked operator, the rule uses a recursive, depth-first algorithm to find the longest chain of nested operator calls. The rule fails if the resulting longest chain of calls exceeds the authorized depth.

Note: an operator calling no other operators has depth 1.

Resolution

Consider refactoring the model to reduce call graph depth, as detailed in the rule failure message.
