Miscellaneous-MaxConditions

An expression must not have more than N logical operators

Required inputs: IR

This rule warns when more than the configured number of logical operators (&& or ||) are used within a single expression.

As an exception, this rule does not warn about complex conditions within custom operator == or operator != definitions. Those operators are often implemented by compare all the class members in a long chain of logical operators.

Rationale

Complex conditions can be hard to understand, and should be split into several statements or extracted into a function.
