void ScannerDfaWriter::writeDfa ( BasicDfaSpec & dfa, BasicDfaProfile & sdp ) [protected]

Referenced by writeScanner().

int ScannerDfaWriter::writeCharCompare ( vector< unsigned char > v, int i ) [protected]

Writes char comparison condition like : (c == 'a') or (('a' <= c) && (c <= 'f')), depending on what characters are found at v[i]; If a single izolated characetr is found, it writes the first form of condition; if a certain amount of successive characters is found, it writed the condition in the second form. IT always returns the first index past the last character in v it has wrtten the condition for. Referenced by writeScanner().

void ScannerDfaWriter::writeExceptionCode ( const string & what, const string & handlerName, bool isName = false ) [protected]

Dumps the code that creates an exception object, calls the handler function whose name is given (onScanError or on IOError) with that object as argument and depending on the return code either throws the exception or calls abort if use of exceptions was disabled. Referenced by writeScanner().
