bool operator()(const SourceRange &L, const SourceRange &R) const
std::set< SourceRange, SourceRangeLessThan > SourceRangeSet
void registerPPCallbacks(const SourceManager &SM, Preprocessor *PP, Preprocessor *ModuleExpanderPP) override
Override this to register PPCallbacks in the preprocessor.
Base class for all clang-tidy checks.
void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register AST matchers with Finder.
static constexpr llvm::StringLiteral Name
void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
