Public Member Functions
	PreprocessorLexer (const PreprocessorLexer &)=delete

PreprocessorLexer &	operator= (const PreprocessorLexer &)=delete

void	LexIncludeFilename (Token &FilenameTok)
	Lex a token, producing a header-name token if possible.

void	setParsingPreprocessorDirective (bool f)
	Inform the lexer whether or not we are currently lexing a preprocessor directive.

bool	isLexingRawMode () const
	Return true if this lexer is in raw mode or not.

Preprocessor *	getPP () const
	Return the preprocessor object for this lexer.

FileID	getFileID () const

unsigned	getInitialNumSLocEntries () const
	Number of SLocEntries before lexing the file.

OptionalFileEntryRef	getFileEntry () const
	getFileEntry - Return the FileEntry corresponding to this FileID.

void	setConditionalLevels (ArrayRef< PPConditionalInfo > CL)

Protected Member Functions
	PreprocessorLexer ()

	PreprocessorLexer (Preprocessor *pp, FileID fid)

virtual	~PreprocessorLexer ()=default

virtual void	IndirectLex (Token &Result)=0

virtual SourceLocation	getSourceLocation ()=0
	Return the source location for the next observable location.

void	pushConditionalLevel (SourceLocation DirectiveStart, bool WasSkipping, bool FoundNonSkip, bool FoundElse)
	pushConditionalLevel - When we enter a #if directive, this keeps track of what we are currently in for diagnostic emission (e.g.

void	pushConditionalLevel (const PPConditionalInfo &CI)

bool	popConditionalLevel (PPConditionalInfo &CI)
	popConditionalLevel - Remove an entry off the top of the conditional stack, returning information about it.

PPConditionalInfo &	peekConditionalLevel ()
	Return the top of the conditional stack.

unsigned	getConditionalStackDepth () const

Protected Attributes
Preprocessor *	PP = nullptr

const FileID	FID
	The SourceManager FileID corresponding to the file being lexed.

unsigned	InitialNumSLocEntries = 0
	Number of SLocEntries before lexing the file.

bool	ParsingPreprocessorDirective = false
	True when parsing #XXX; turns '\n' into a tok::eod token.

bool	ParsingFilename = false
	True after #include; turns or "xxx" into a tok::header_name token.

bool	LexingRawMode = false
	True if in raw mode.

MultipleIncludeOpt	MIOpt
	A state machine that detects the #ifndef-wrapping a file idiom for the multiple-include optimization.

SmallVector< PPConditionalInfo, 4 >	ConditionalStack
	Information about the set of #if/#ifdef/#ifndef blocks we are currently in.
