NodeType Type
Base class for all clang-tidy checks.
Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
Base class for MakeSharedCheck and MakeUniqueCheck.
virtual SmartPtrTypeMatcher getSmartPointerTypeMatcher() const =0
Returns matcher that match with different smart pointer types.
void check(const ast_matchers::MatchFinder::MatchResult &Result) final
ClangTidyChecks that register ASTMatchers should do the actual work in here.
bool isLanguageVersionSupported(const LangOptions &LangOpts) const override
Returns whether the C++ version is compatible with current check.
void registerPPCallbacks(const SourceManager &SM, Preprocessor *PP, Preprocessor *ModuleExpanderPP) override
Override this to register PPCallbacks in the preprocessor.
void storeOptions(ClangTidyOptions::OptionMap &Opts) override
Should store all options supported by this check with their current values or default values for opti...
void registerMatchers(ast_matchers::MatchFinder *Finder) final
Override this to register AST matchers with Finder.
ast_matchers::internal::BindableMatcher< QualType > SmartPtrTypeMatcher
Produces fixes to insert specified includes to source files, if not yet present.
