Re: [lang] CloneUtils

[Shaun Kalley]

I've included my code below.  I have another if you're able to answer 
it: why is the lang subproject home to classes dealing with 
serialization?  Shouldn't they be part of the IO subproject?

Thanks,
Shaun
   /**
    * <p>Clones a serializable object by serializing and deserializing 
it.</p>
    *
    * @param obj the object to clone.
    * @return a clone of the object, or null if the object is null.
    * @throws SerializationException if the serialization process fails.
    */
   public static Object cloneSerializable(Serializable obj) throws 
SerializationException {
       if (obj == null) {
           return null;
       }
       ObjectOutputStream oos = null;
       ObjectInputStream ois = null;
       try {
           ByteArrayOutputStream baos = new ByteArrayOutputStream(512);
           oos = new ObjectOutputStream(baos);
           oos.writeObject(obj);
           oos.flush();
           ois = new ObjectInputStream(new 
ByteArrayInputStream(baos.toByteArray()));
           return ois.readObject();
       } catch (Exception e) {
           throw new SerializationException("Failed to clone 
serializable object.", e);
       } finally {
           if (ois != null) {
               try {
                  ois.close();
               } catch (IOException ignored) {
               }
           }
           if (oos != null) {
               try {
                   oos.close();
               } catch (IOException ignored) {
               }
           }
       }
   }

Thanks Shaun - I'd be happy to have the code if you'll send it along.

The only substantial difference in my code is a shortcut to return null
if the object is null.  (Sorry to send two replies!)

SerializationUtils already has a clone() method.  Is your code different
     

from that?

Hi, Kevin and everyone,

I've got code for cloning serializable objects that I'd be happy to
contribute to the project.  Let me know if you'd like it as a starting
point.

Thanks,
Shaun Kalley

Hello all,

In the interest of jumping feet first into commons-lang, I'm hoping to
start work on CloneUtils (from the tasks list).  Before I start any
serious design/coding, I'd like to ask for any suggestions as to
features of the class (assuming, of course, that no one has anything
completed already).  I was planning on implementing serialization
cloning, and maybe super-simple public fields cloning if it's worth
it.  I would appreciate any suggestions/tips/etc. anyone has to offer.

Thanks,
Kevin Gessner
