value
- the value to encode. This will never be null
.out
- the data output stream to encode the value to.utils
- additional utility encoding functions that may be useful to the codec.IOException
- if an I/O error occurs.T decode(DataInput in, ClassLoader cl, DecoderUtils utils) throws IOException
in
- the data input stream to decode the value from.cl
- a classloader which can be used to load classes necessary
to decode the value.utils
- additional utility decoding functions that may be useful to the codec.IOException
- if an I/O error occurs.
