Method Detail

consume

public void consume()

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.

LA

public int LA(int i)

LT

public Token LT(int i)

traceIn

public void traceIn(String rname)

traceOut

public void traceOut(String rname)
