Detailed Description

Finds using namespace directives.

https://google.github.io/styleguide/cppguide.html#Namespaces

The check implements the following rule of the Google C++ Style Guide:

You may not use a using-directive to make all names from a namespace available.

// Forbidden -- This pollutes the namespace.
using namespace foo;

Corresponding cpplint.py check name: build/namespaces.

Member Function Documentation

◆ check()

void clang::tidy::google::build::UsingNamespaceDirectiveCheck::check ( const ast_matchers::MatchFinder::MatchResult &  Result)
overridevirtual

ClangTidyChecks that register ASTMatchers should do the actual work in here.

◆ registerMatchers()

void clang::tidy::google::build::UsingNamespaceDirectiveCheck::registerMatchers ( ast_matchers::MatchFinder *  Finder)
overridevirtual

Override this to register AST matchers with Finder.

This should be used by clang-tidy checks that analyze code properties that dependent on AST knowledge.

You can register as many matchers as necessary with Finder. Usually, "this" will be used as callback, but you can also specify other callback classes. Thereby, different matchers can trigger different callbacks.

If you need to merge information between the different matchers, you can store these as members of the derived class. However, note that all matches occur in the order of the AST traversal.
