Member Function Documentation

virtual void 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 Parser.

virtual int 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 Parser.

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

Return the i-th token of lookahead.

Implements Parser.

void LLkParser::traceIn (  const char *    rname )  [virtual]
 

Reimplemented from Parser.

void LLkParser::traceOut (  const char *    rname )  [virtual]
 

Reimplemented from Parser.
