方法详细资料

decode

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 ClassCastException occurs this decode method will throw a DecoderException.

参数:

pObject - an object to "decode"

返回:

a 'decoded" object

抛出:

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.
