public interface Decoder {

    
Decodes 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 java.lang.ClassCastException occurs this decode method will throw a DecoderException.

Parameters:
source the object to decode
Returns:
a 'decoded" object
Throws:
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.
