package org.apache.commons.codec;

 * Provides the highest level of abstraction for Decoders.
 * <p>
 * This is the sister interface of {@link Encoder}. All Decoders implement this common generic interface.
 * Allows a user to pass a generic Object to any Decoder implementation in the codec package.
 * <p>
 * One of the two interfaces at the center of the codec package.
public interface Decoder {

     * 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 ClassCastException} occurs this decode method will throw a DecoderException.
     * @param source
     *            the 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.
    Object decode(Object source) throws DecoderException;
