  - ### Method Detail

    - #### createSink

          public ClientDataSink createSink()

      Description copied from interface: `ClientDataEncoder`
      Creates a sink for client data. The sink provides an output stream and ultimately, a string representation of the data sent to the stream.
      Specified by:
        `createSink` in interface `ClientDataEncoder`
      Returns:
        a new sink

    - #### decodeClientData

          public ObjectInputStream decodeClientData(String clientData)

      Description copied from interface: `ClientDataEncoder`
      Decodes data previously obtained from `ClientDataSink.getClientData()`.
      Specified by:
        `decodeClientData` in interface `ClientDataEncoder`
      Parameters:
        `clientData` - encoded client data
      Returns:
        stream of decoded data

          public ObjectInputStream decodeEncodedClientData(String clientData)
                                                    throws IOException

      Description copied from interface: `ClientDataEncoder`
      Decodes client data obtained via `ClientDataSink.getEncodedClientData()`.
      Specified by:
        `decodeEncodedClientData` in interface `ClientDataEncoder`
      Parameters:
        `clientData` - URLEncoded client data
      Returns:
        stream of objects
      Throws:
        `IOException` - if the client data has been corrupted (verified via the HMAC)
