decode

java.lang.Object decode(java.lang.Object source)
                        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:

source - the object to decode

返回:

a 'decoded" object

抛出:

org.apache.commons.codec.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.
