question: public void consumeGreedy ( String greedyToken ) { if ( greedyToken . length ( ) < sval . length ( ) ) { pushBack ( ) ; setStartPosition ( getStartPosition ( ) + greedyToken . length ( ) ) ; sval = sval . substring ( greedyToken . length ( ) ) ; } }
target:  Consumes a substring from the current sval of the StreamPosTokenizer.
