clang: clang::TokenLexer Class Reference

TokenLexer - This implements a lexer that returns tokens from a macro body or token stream instead of lexing from a character buffer. More...

#include "clang/Lex/TokenLexer.h"

TokenLexer (Token &Tok, SourceLocation ILEnd, MacroInfo *MI, MacroArgs *ActualArgs, Preprocessor &pp) Create a TokenLexer for the specified macro with the specified actual arguments.
TokenLexer (const Token *TokArray, unsigned NumToks, bool DisableExpansion, bool ownsTokens, bool isReinject, Preprocessor &pp) Create a TokenLexer for the specified token stream.
TokenLexer (const TokenLexer &)=delete TokenLexer & operator= (const TokenLexer &)=delete ~TokenLexer () void Init (Token &Tok, SourceLocation ELEnd, MacroInfo *MI, MacroArgs *Actuals) Initialize this TokenLexer to expand from the specified macro with the specified argument information.
void Init (const Token *TokArray, unsigned NumToks, bool DisableMacroExpansion, bool OwnsTokens, bool IsReinject) Initialize this TokenLexer with the specified token stream.
unsigned isNextTokenLParen () const If the next token lexed will pop this macro off the expansion stack, return 2.
bool Lex (Token &Tok) Lex and return a token from this macro stream.
bool isParsingPreprocessorDirective () const isParsingPreprocessorDirective - Return true if we are in the middle of a preprocessor directive.

TokenLexer - This implements a lexer that returns tokens from a macro body or token stream instead of lexing from a character buffer.

This is used for macro expansion and _Pragma handling, for example.

◆ TokenLexer() [1/3]

Create a TokenLexer for the specified macro with the specified actual arguments.

Note that this ctor takes ownership of the ActualArgs pointer. ILEnd specifies the location of the ')' for a function-like macro or the identifier for an object-like macro.

Definition at line 108 of file TokenLexer.h.

References clang::Init.

◆ TokenLexer() [2/3]

Create a TokenLexer for the specified token stream.

If 'OwnsTokens' is specified, this takes ownership of the tokens and delete[]'s them when the token lexer is empty.

◆ Init() [1/2] void TokenLexer::Init ( const Token * TokArray, unsigned NumToks, bool disableMacroExpansion, bool ownsTokens, bool isReinject ) ◆ Init() [2/2]

Initialize this TokenLexer to expand from the specified macro with the specified argument information.

Create a TokenLexer for the specified macro with the specified actual arguments.

Note that this ctor takes ownership of the ActualArgs pointer. ILEnd specifies the location of the ')' for a function-like macro or the identifier for an object-like macro.

◆ isNextTokenLParen() unsigned TokenLexer::isNextTokenLParen ( ) const

If the next token lexed will pop this macro off the expansion stack, return 2.

isNextTokenLParen - If the next token lexed will pop this macro off the expansion stack, return 2.

If the next unexpanded token is a '(', return 1, otherwise return 0.
