Examples of java.io.ObjectOutputStream.writeUnshared()

java.io.ObjectOutputStream.writeUnshared()
Write object object into the receiver's underlying stream unshared with previously written identical objects. @param object The object to write @throws IOException If an IO exception happened when writing the object @see ObjectInputStream#readObject()

      // serialize obj
      ByteArrayOutputStream baos = new ByteArrayOutputStream();
      oos = new ObjectOutputStream(baos);
      // oos.reset(); -- not needed here because the oos is
      //                 always a new instance, reseted.
      oos.writeUnshared(message);
      byte[] byteObj = baos.toByteArray();
      
      baos.reset();
      
      // compact the serialization
