Encoding and decoding certain type of Objects works like DataValue. Whereas anything which implements Structure is causing issues while decoding. please provide an example. I tired options like VariableNode. Keep trowing errors like ERROR – org.opcfoundation.ua.encoding.DecodingException: Bad_DecodingError (code=0x80070000, description=”Unexpected encoding byte (3) in ExtensionObject”).

Here is decoder sample code:
ByteBuffer byteBuffer = ByteBuffer.wrap(buffer.array());
byteBuffer.order(ByteOrder.LITTLE_ENDIAN);
org.opcfoundation.ua.encoding.binary.BinaryDecoder opcdecoder = new org.opcfoundation.ua.encoding.binary.BinaryDecoder(byteBuffer);
Structure structure = opcdecoder.getStructure(null);

The Encoder and Decoder classes are mainly for the internal use of the stack. But obviously you are using them for your own streaming as you described earlier.

You will need to specify the EncoderContext for the encoder & decoder. The structure fields are encoded as ExtensionObjects which makes it more complicated than builtin values.

This goes quite low level, so I am not quite sure how it should be used for this kind of custom streaming.
