Member Function Documentation

◆ check()

void clang::tidy::abseil::StringFindStartswithCheck::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 80 of file StringFindStartswithCheck.cpp.

References clang::tidy::utils::IncludeInserter::createIncludeInsertion(), clang::tidy::ClangTidyCheck::diag(), and Diagnostic.

◆ ClangTidyCheck()

clang::tidy::ClangTidyCheck::ClangTidyCheck	(	StringRef	CheckName,
		ClangTidyContext *	Context
	)

Initializes the check with CheckName and Context.

Derived classes must implement the constructor with this signature or delegate it. If a check needs to read options, it can do this in the constructor using the Options.get() methods below.

Definition at line 60 of file ClangTidyCheck.cpp.

◆ isLanguageVersionSupported()

bool clang::tidy::abseil::StringFindStartswithCheck::isLanguageVersionSupported ( const LangOptions & LangOpts ) const

inlineoverridevirtual

Override this to disable registering matchers and PP callbacks if an invalid language version is being used.

For example if a check is examining overloaded functions then this should be overridden to return false when the CPlusPlus flag is not set in LangOpts.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 33 of file StringFindStartswithCheck.h.

◆ registerMatchers()

void clang::tidy::abseil::StringFindStartswithCheck::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.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 36 of file StringFindStartswithCheck.cpp.

◆ registerPPCallbacks()

void clang::tidy::abseil::StringFindStartswithCheck::registerPPCallbacks	(	const SourceManager &	SM,
		Preprocessor *	PP,
		Preprocessor *	ModuleExpanderPP
	)

overridevirtual

Override this to register PPCallbacks in the preprocessor.

This should be used for clang-tidy checks that analyze preprocessor- dependent properties, e.g. include directives and macro definitions.

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

There are two Preprocessors to choose from that differ in how they handle modular #includes:

PP is the real Preprocessor. It doesn't walk into modular #includes and thus doesn't generate PPCallbacks for their contents.
ModuleExpanderPP preprocesses the whole translation unit in the non-modular mode, which allows it to generate PPCallbacks not only for the main file and textual headers, but also for all transitively included modular headers when the analysis runs with modules enabled. When modules are not enabled ModuleExpanderPP just points to the real preprocessor.
