Public Member Functions inherited from clang::tidy::ClangTidyCheck
	ClangTidyCheck (StringRef CheckName, ClangTidyContext *Context)
	Initializes the check with `CheckName` and `Context`.

virtual bool	isLanguageVersionSupported (const LangOptions &LangOpts) const
	Override this to disable registering matchers and PP callbacks if an invalid language version is being used.

virtual void	registerPPCallbacks (const SourceManager &SM, Preprocessor PP, Preprocessor ModuleExpanderPP)
	Override this to register `PPCallbacks` in the preprocessor.

virtual void	registerMatchers (ast_matchers::MatchFinder *Finder)
	Override this to register AST matchers with `Finder`.

virtual void	check (const ast_matchers::MatchFinder::MatchResult &Result)
	`ClangTidyChecks` that register ASTMatchers should do the actual work in here.

DiagnosticBuilder	diag (SourceLocation Loc, StringRef Description, DiagnosticIDs::Level Level=DiagnosticIDs::Warning)
	Add a diagnostic with the check's name.

DiagnosticBuilder	diag (StringRef Description, DiagnosticIDs::Level Level=DiagnosticIDs::Warning)
	Add a diagnostic with the check's name.

DiagnosticBuilder	configurationDiag (StringRef Description, DiagnosticIDs::Level Level=DiagnosticIDs::Warning) const
	Adds a diagnostic to report errors in the check's configuration.

virtual void	storeOptions (ClangTidyOptions::OptionMap &Options)
	Should store all options supported by this check with their current values or default values for options that haven't been overridden.

void	registerMatchersImpl (ast_matchers::MatchFinder *Finder, ast_matchers::internal::Matcher< FunctionDecl > Function)

void	insertMacroFlag (const ast_matchers::MatchFinder::MatchResult &Result, StringRef MacroFlag, int ArgPos)
	Currently, we have three types of fixes.

void	replaceFunc (const ast_matchers::MatchFinder::MatchResult &Result, StringRef WarningMsg, StringRef FixMsg)
	Type2 is to replace the API to another function that has required the ability.

void	insertStringFlag (const ast_matchers::MatchFinder::MatchResult &Result, const char Mode, const int ArgPos)
	Type3 is also to add a flag to the corresponding argument, but this time, the flag is some string and each char represents a mode rather than a macro.

StringRef	getSpellingArg (const ast_matchers::MatchFinder::MatchResult &Result, int N) const
	Helper function to get the spelling of a particular argument.

Protected Member Functions inherited from clang::tidy::ClangTidyCheck

const LangOptions &	getLangOpts () const
	Returns the language options from the context.

bool	areDiagsSelfContained () const
	Returns true when the check is run in a use case when only 1 fix will be applied at a time.

Member Function Documentation

◆ check()

void clang::tidy::android::CloexecSocketCheck::check ( const ast_matchers::MatchFinder::MatchResult & Result )

overridevirtual

ClangTidyChecks that register ASTMatchers should do the actual work in here.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 26 of file CloexecSocketCheck.cpp.

References clang::tidy::android::CloexecCheck::insertMacroFlag().

◆ registerMatchers()

void clang::tidy::android::CloexecSocketCheck::registerMatchers ( ast_matchers::MatchFinder * Finder )

overridevirtual

Override this to register AST matchers with Finder.

This should be used by clang-tidy checks that analyze code properties that dependent on AST knowledge.

You can register as many matchers as necessary with Finder. Usually, "this" will be used as callback, but you can also specify other callback classes. Thereby, different matchers can trigger different callbacks.

This will only be executed if the function isLanguageVersionSupported returns true.

If you need to merge information between the different matchers, you can store these as members of the derived class. However, note that all matches occur in the order of the AST traversal.
