Member Function Documentation

virtual void antlr::LLkParser::consume ( ) [inline, virtual]

Consume another token from the input stream. Can only write sequentially! If you need 3 tokens ahead, you must consume() 3 times.

Note that it is possible to overwrite tokens that have not been matched. For example, calling consume() 3 times when k=2, means that the first token consumed will be overwritten with the 3rd.

Implements antlr::Parser.

virtual int antlr::LLkParser::LA ( unsigned int i ) [inline, virtual]

Return the token type of the ith token of lookahead where i=1 is the current token being examined by the parser (i.e., it has not been matched yet).

Implements antlr::Parser.

virtual RefToken antlr::LLkParser::LT ( unsigned int i ) [inline, virtual]

Return the i-th token of lookahead.

Implements antlr::Parser.
