Member Typedef Documentation

◆ NamingCheckFailureMap

using clang::tidy::RenamerClangTidyCheck::NamingCheckFailureMap

Initial value:

llvm::DenseMap<NamingCheckId, NamingCheckFailure>

Definition at line 107 of file RenamerClangTidyCheck.h.

◆ NamingCheckId

using clang::tidy::RenamerClangTidyCheck::NamingCheckId = std::pair<SourceLocation, StringRef>

Definition at line 105 of file RenamerClangTidyCheck.h.

Member Enumeration Documentation

◆ ShouldFixStatus

enum class clang::tidy::RenamerClangTidyCheck::ShouldFixStatus

strong

This enum will be used in select of the diagnostic message.

Each value below IgnoreFailureThreshold should have an error message.

Enumerator
ShouldFix
ConflictsWithKeyword	The fixup will conflict with a language keyword, so we can't fix it automatically.
ConflictsWithMacroDefinition	The fixup will conflict with a macro definition, so we can't fix it automatically.
FixInvalidIdentifier	The fixup results in an identifier that is not a valid c/c++ identifier.
IgnoreFailureThreshold	Values pass this threshold will be ignored completely i.e no message, no fixup.
InsideMacro	If the identifier was used or declared within a macro we won't offer a fixup for safety reasons.

◆ checkMacro()

void clang::tidy::RenamerClangTidyCheck::checkMacro	(	const Token &	MacroNameTok,

◆ expandMacro()

void clang::tidy::RenamerClangTidyCheck::expandMacro	(	const Token &	MacroNameTok,
		const MacroInfo *	MI,

◆ getDeclFailureInfo()

virtual std::optional< FailureInfo > clang::tidy::RenamerClangTidyCheck::getDeclFailureInfo	(	const NamedDecl *	Decl,
		const SourceManager &	SM ) const

protectedpure virtual

Overridden by derived classes, returns information about if and how a Decl failed the check.

A 'std::nullopt' result means the Decl did not fail the check.

Referenced by addUsage().

◆ getDiagInfo()

virtual DiagInfo clang::tidy::RenamerClangTidyCheck::getDiagInfo	(	const NamingCheckId &	ID,
		const NamingCheckFailure &	Failure ) const

protectedpure virtual

Overridden by derived classes, returns a description of the diagnostic that should be emitted for the given failure.

The base class will then further customize the diagnostic by adding info about whether the fix-it can be automatically applied or not.

◆ getMacroFailureInfo()

virtual std::optional< FailureInfo > clang::tidy::RenamerClangTidyCheck::getMacroFailureInfo	(	const Token &	MacroNameTok,
		const SourceManager &	SM ) const

protectedpure virtual

Overridden by derived classes, returns information about if and how a macro failed the check.
