public interface DecoderProvides the highest level of abstraction for Decoders.
This is the sister interface of
Encoder. All Decoders implement this common generic interface. Allows a user to pass a generic Object to any Decoder implementation in the codec package.
One of the two interfaces at the center of the codec package.
Object decode(Object source) throws DecoderExceptionDecodes an "encoded" Object and returns a "decoded" Object. Note that the implementation of this interface will try to cast the Object parameter to the specific type expected by a particular Decoder implementation. If a
ClassCastExceptionoccurs this decode method will throw a DecoderException.
source- the object to decode
- a 'decoded" object
DecoderException- a decoder exception can be thrown for any number of reasons. Some good candidates are that the parameter passed to this method is null, a param cannot be cast to the appropriate type for a specific encoder.
