Class TFTPErrorPacket

java.lang.Object
com.oroinc.net.tftp.TFTPPacket
com.oroinc.net.tftp.TFTPErrorPacket

public final class TFTPErrorPacket extends TFTPPacket
A final class derived from TFTPPacket definiing the TFTP Error packet type.

Details regarding the TFTP protocol and the format of TFTP packets can be found in RFC 783. But the point of these classes is to keep you from having to worry about the internals. Additionally, only very few people should have to care about any of the TFTPPacket classes or derived classes. Almost all users should only be concerned with the TFTPClient class receiveFile() and sendFile() methods.

      Specified by:
      newDatagram in class TFTPPacket
      Returns:
      A UDP datagram containing the TFTP error packet.
