Class XdrDynamicOpaque

java.lang.Object
  org.acplt.oncrpc.XdrDynamicOpaque

All Implemented Interfaces:

XdrAble

public class XdrDynamicOpaque
extends java.lang.Object
implements XdrAble

Instances of the class XdrDynamicOpaque represent (de-)serializeable dynamic-size opaque values, which are especially useful in cases where a result with only a single opaque value is expected from a remote function call or only a single opaque value parameter needs to be supplied.

Please note that this class is somewhat modelled after Java's primitive data type wrappers. As for these classes, the XDR data type wrapper classes follow the concept of values with no identity, so you are not allowed to change the value after you've created a value object.

xdrEncode

public void xdrEncode(XdrEncodingStream xdr)
               throws OncRpcException,
                      java.io.IOException

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

Specified by:

xdrEncode in interface XdrAble

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.

xdrDecode

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

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

Specified by:

xdrDecode in interface XdrAble

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.
