      edu.berkeley.psi.tagged.api.Opaque

All Implemented Interfaces:

TaggedIF, XdrAble

public class Opaque
extends Tagged

A Tagged wrapper around an opaque (uninterpreted) byte[] array. The Opaque(byte[]) constructor shares the byte[] buffer with the caller, while the Opaque(byte[],int,int) constructor makes a copy of the data.

xdrDecode

public void xdrDecode(XdrDecodingStream xdr)
               throws OncRpcException,
                      java.io.IOException

Deserialize an opaque byte[] buffer from a stream

Parameters:

xdr - XDR stream from which decoded information is retrieved.

Throws:

OncRpcException - if an ONC/RPC error occurs.

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

xdrEncode

               throws OncRpcException,
                      java.io.IOException

Serialize an opaque byte[] buffer to a XdrEncodingStream

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.

newInstance

static Opaque newInstance()
