All Implemented Interfaces:

java.io.Serializable

public class TftpErrorException
extends java.io.IOException

Thrown to indicate that a TFTP error has occurred. A TftpErrorException is thrown as a result of a remote error, that is, an error signaled by the remote host. Since all TFTP errors cause the termination of the request, once a TftpErrorException has been thrown the request must be abandoned and no further communication must be tried.

A TftpErrorException has a numeric error code, indicating the nature of the error, and a descriptive text message. The class defines convenient constants for all standard error codes specified by the TFTP standard. The text message may be empty, but is guaranteed to be non-null.
