Description copied from interface: XdrAble

Decodes -- that is: deserializes -- an object from a XDR stream in compliance to RFC 1832.

Parameters:

xdr - XDR stream from which decoded information is retrieved.

Throws:

OncRpcException - if an ONC/RPC error occurs.

Description copied from interface: XdrAble

Encodes -- that is: serializes -- an object into a XDR stream in compliance to RFC 1832.

Parameters:

xdr - XDR stream to which information is sent for encoding.

Throws:

OncRpcException - if an ONC/RPC error occurs.

java.io.IOException - if an I/O error occurs.
