If I read it correctly, pack() turns the tuple into bytes and unpack() turns such bytes back into a tuple. Is this true?
If so, check out how serialization works. You can then write entire objects into any output stream using an
. To convert an object into bytes and back you can use the following:
ByteArrayOutputStream baos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(baos); oos.writeObject(object); oos.flush(); oos.close(); byte bytes = baos.toByteArray(); // converting back ByteArrayInputStream bais = new ByteArrayInputStream(bytes); ObjectInputStream ois = new ObjectInputStream(bais); MyObject object2 = (MyObject)ois.readObject();
