void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
void storeOptions(ClangTidyOptions::OptionMap &Opts) override
Should store all options supported by this check with their current values or default values for opti...
IncludeStyle
Supported include styles.
Definition: IncludeSorter.h:26
Base class for all clang-tidy checks.
void registerPPCallbacks(const SourceManager &SM, Preprocessor *PP, Preprocessor *ModuleExpanderPP) override
Override this to register PPCallbacks in the preprocessor.
StringFindStartswithCheck(StringRef Name, ClangTidyContext *Context)
static constexpr llvm::StringLiteral Name
std::map< std::string, std::string > OptionMap
ClangTidyCheck(StringRef CheckName, ClangTidyContext *Context)
Initializes the check with CheckName and Context.
===– Representation.cpp - ClangDoc Representation --------—*- C++ -*-===//
Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register AST matchers with Finder.
