If a java.lang.ClassCastException occurs this decode method will throw a DecoderException. Parameters: pObject - an object to "decode" a 'decoded" object throws: DecoderException - a decoder exception canbe thrown for any number of reasons. Some goodcandidates are that the parameter passed to thismethod is null, a param cannot be cast to theappropriate type for a specific encoder.
