Class OncRpcCallMessage

java.lang.Object
  org.acplt.oncrpc.OncRpcMessage
      org.acplt.oncrpc.OncRpcCallMessage

Direct Known Subclasses:

OncRpcClientCallMessage, OncRpcServerCallMessage

public abstract class OncRpcCallMessage
extends OncRpcMessage

The OncRpcCallMessage class represents a remote procedure call message as defined by ONC/RPC in RFC 1831. Such messages are sent by ONC/RPC clients to servers in order to request a remote procedure call.

Note that this is an abstract class. Because call message objects also need to deal with authentication protocol issues, they need help of so-called authentication protocol handling objects. These objects are of different classes, depending on where they are used (either within the server or the client).

Please also note that this class implements no encoding or decoding functionality: it doesn't need them. Only derived classes will be able to be encoded on the side of the client and decoded at the end of the server.
