std::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 std::nullopt if no qualifying tokens are found.

Note

: doesn't support member function qualifiers.
