Base class for all clang-tidy checks.
Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
Multiple implementation inheritance is discouraged.
void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register AST matchers with Finder.
MultipleInheritanceCheck(StringRef Name, ClangTidyContext *Context)
bool isLanguageVersionSupported(const LangOptions &LangOpts) const override
Override this to disable registering matchers and PP callbacks if an invalid language version is bein...
void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
