		const SourceManager &	SM,
		const LangOptions &	LangOpts,
		tok::TokenKind	TK
	)

getPreviousToken()

Token clang::tidy::utils::lexer::getPreviousToken	(	SourceLocation	Location,
		const SourceManager &	SM,
		const LangOptions &	LangOpts,
		bool	SkipComments
	)

Returns previous token or tok::unknown if not found.

Definition at line 18 of file LexerUtils.cpp.

getQualifyingToken()

llvm::Optional< Token > clang::tidy::utils::lexer::getQualifyingToken	(	tok::TokenKind	TK,
		CharSourceRange	Range,
		const ASTContext &	Context,
		const SourceManager &	SM
	)

Assuming that Range spans a CVR-qualified type, returns the token in Range that is responsible for the qualification.

Range must be valid with respect to SM. Returns None if no qualifying tokens are found.

Note

: doesn't support member function qualifiers.

getSemicolonAfterStmtEndLoc()

static SourceLocation clang::tidy::utils::lexer::getSemicolonAfterStmtEndLoc ( const SourceLocation &  EndLoc, const SourceManager &  SM, const LangOptions &  LangOpts  )

static

Definition at line 163 of file LexerUtils.cpp.

getUnifiedEndLoc()

SourceLocation clang::tidy::utils::lexer::getUnifiedEndLoc	(	const Stmt &	S,
		const SourceManager &	SM,
		const LangOptions &	LangOpts
	)

Stmt->getEndLoc does not always behave the same way depending on Token type.

See implementation for exceptions.

bool clang::tidy::utils::lexer::rangeContainsExpansionsOrDirectives	(	SourceRange	Range,
		const SourceManager &	SM,
		const LangOptions &	LangOpts
	)

Re-lex the provide Range and return false if either a macro spans multiple tokens, a pre-processor directive or failure to retrieve the next token is found, otherwise true.
