net.azib.ipscan.core.ScanningSubject
Scanning subject represents a single scanned IP address and any additional arbitrary parameters, which may be used to cache some intermediate data among different Fetchers. @author Anton Keks

Examples of net.azib.ipscan.core.ScanningSubject

  public ScanningSubject next() {
    currentNumber++;
    random.nextBytes(currentBytes);
    try {
      InetAddressUtils.maskPrototypeAddressBytes(currentBytes, maskBytes, prototypeBytes);
      return new ScanningSubject(InetAddress.getByAddress(currentBytes));
    }
    catch (UnknownHostException e) {
      // this should never happen
      throw new RuntimeException(e);

    // this method must be fast, so we are not checking all the implementations    
    // currently only icmp pingers may not be supported, so let's check them
