Base class for all clang-tidy checks.
ClangTidyCheck(StringRef CheckName, ClangTidyContext *Context)
Initializes the check with CheckName and Context.
Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
void storeOptions(ClangTidyOptions::OptionMap &Opts) override
Should store all options supported by this check with their current values or default values for opti...
bool isLanguageVersionSupported(const LangOptions &LangOpts) const override
Override this to disable registering matchers and PP callbacks if an invalid language version is bein...
void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register AST matchers with Finder.
void registerPPCallbacks(const SourceManager &SM, Preprocessor *PP, Preprocessor *ModuleExpanderPP) override
Override this to register PPCallbacks in the preprocessor.
void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
Produces fixes to insert specified includes to source files, if not yet present.
