public java.lang.Objectdecode(java.lang.Object pObject)
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 {@link java.lang.ClassCastException} occurs this decode method will throw a DecoderException.

param
pObject an object to "decode"
return
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.
