All Implemented Interfaces:
DataReceiver
public class TransferControl extends Object implements DataReceiver
Class for managing the transmission process between a block sender and the associated receiver. It implements the DataReceiver interface

  • Field Details

    • PARTNER_ID

      public static final String PARTNER_ID
      String used for testing whether a receiver is available. Together with this string the ID of the current key is sent and the recipient replies with "Ready:OK" if he also has exactly this key, otherwise with "Ready:NOK".
      See Also:

    • PARTNER_RESPONSE

      public static final String PARTNER_RESPONSE
      String that the receiver sends as a response if it was addressed by the sender with the PARTNER_ID + key ID. It completes the response with "OK" if it also possesses the key with the sent key ID and with "NOK" if it does not possess this key.
      See Also:

    • TRANSFER_BREAK

      public static final String TRANSFER_BREAK
      String that the receiver sends as a response if errors occur during reception and evaluation or use of the received data and regular reception cannot be performed.
