Example 1 with FunctionLike

use of org.sonar.uast.helpers.FunctionLike in project sonar-go by SonarSource.

    if (function == null) {
        return;
    }

        parameter.getDescendants(UastNode.Kind.IDENTIFIER, identifiers::add, UastNode.Kind.TYPE);
        parameterCount += identifiers.size();
    }
    if (parameterCount > maximum) {
        reportIssue(function.name(), String.format("Function has %d parameters, which is more than %d authorized.", parameterCount, maximum));
    }
}

Example 2 with FunctionLike

use of org.sonar.uast.helpers.FunctionLike in project sonar-go by SonarSource.

the class FunctionCognitiveComplexityCheck method visitNode.

        String message = "Refactor this function to reduce its Cognitive Complexity from " + complexity.value() + " to the " + maxComplexity + " allowed.";
        int effortToFix = complexity.value() - maxComplexity;
        reportIssue(functionNode.name(), functionNode.name(), message, effortToFix, complexity.secondaryLocations());
    }
