static void AddCXXOperatorKeyword	(	StringRef	Keyword,
		tok::TokenKind	TokenCode,
		IdentifierTable &	Table
	)		[static]

AddCXXOperatorKeyword - Register a C++ operator keyword alternative representations.

Definition at line 170 of file IdentifierTable.cpp.

References clang::IdentifierTable::get(), and clang::IdentifierInfo::setIsCPlusPlusOperatorKeyword().

static void AddKeyword	(	StringRef	Keyword,
		tok::TokenKind	TokenCode,
		unsigned	Flags,
		const LangOptions &	LangOpts,
		IdentifierTable &	Table
	)		[static]

AddKeyword - This method is used to associate a token ID with specific identifiers because they are language keywords. This causes the lexer to automatically map matching identifiers to specialized token codes.

static void AddObjCKeyword	(	StringRef	Name,
		tok::ObjCKeywordKind	ObjCID,
		IdentifierTable &	Table

AddObjCKeyword - Register an Objective-C @keyword like "class" "selector" or "property".

static KeywordStatus GetKeywordStatus	(	const LangOptions &	LangOpts,
