Class OncRpcClientReplyMessage

public class OncRpcClientReplyMessage extends OncRpcReplyMessage
The OncRpcReplyMessage class represents an ONC/RPC reply message as defined by ONC/RPC in RFC 1831. Such messages are sent back by ONC/RPC to servers to clients and contain (in case of real success) the result of a remote procedure call.

The decision to define only one single class for the accepted and rejected replies was driven by the motivation not to use polymorphism and thus have to upcast and downcast references all the time.

The derived classes are only provided for convinience on the server side.

  • Constructor Details

    • OncRpcClientReplyMessage

      public OncRpcClientReplyMessage(OncRpcClientAuth auth)
      Initializes a new RPC reply message object to represent an invalid state OncRpcReplyMessage. This default constructor should only be used if in the next step the real state of the reply message is immediately decoded from a XDR stream.

  • Method Details

    • successfullyAccepted

      public boolean successfullyAccepted()
      Check whether this OncRpcReplyMessage represents an accepted and successfully executed remote procedure call.
      Returns:
      true if remote procedure call was accepted and successfully executed.

    • newException

      public OncRpcException newException()
      Return an appropriate exception object according to the state this reply message header object is in. The exception object then can be thrown.
      Returns:
      Exception object of class OncRpcException or a subclass thereof.

    • xdrDecode

      public void xdrDecode(XdrDecodingStream xdr) throws OncRpcException, IOException
      Decodes -- that is: deserializes -- a ONC/RPC message header object from a XDR stream.
      Parameters:
      xdr - An instance of class XdrDecodingStream.
