Provides 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 pObject) - Decodes an "encoded" Object and returns a "decoded"
Object.

decode
public Object decode(Object pObject)
throws DecoderException
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.
pObject
- an 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.
