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.

Definition at line 39 of file LLkParser.hpp.

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.

Definition at line 44 of file LLkParser.hpp.

virtual RefToken LLkParser::LT

(

unsigned int

i

)

[inline, virtual]

Return the i-th token of lookahead.

Implements Parser.
