is called by methods of DfaRun in case of a match. Parameter yytext contains the matching text from position start onwards. The callback may change the whole of yytext, but the under most circumstances, only the matching text should be changed. Parameter runner is the DfaRun object which called this function. Of interest are its fields DfaRun.clientData and DfaRun.collect.
