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.

) | [inline] |
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.

clang::TokenLexer::TokenLexer | ( | const Token * | TokArray, |

bool | DisableExpansion, | ||

Preprocessor & | pp | ||
) | [inline] |
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 - Initialize this TokenLexer to expand from the specified macro with the specified argument information. 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.
Create a TokenLexer for the specified macro with the specified actual arguments. Note that this ctor takes ownership of the ActualArgs pointer.

Init - Initialize this TokenLexer with the specified token stream. This does not take ownership of the specified token vector.
DisableExpansion is true when macro expansion of tokens lexed from this stream should be disabled.
Create a TokenLexer for the specified token stream. This does not take ownership of the specified token vector.

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.
