title: Substitute for Iterator that is Serialization
body: <p>I'm working on a GWT project, and I have a bunch of Java classes that use Java Object Iterators on the server side. As I was reading through the internet...Iterators seem to not be serializable preventing me from sending them over to the client side from the server side.
  My question is is there an efficient way to serialize the iterator or use a substitute that might be serializable ?</p>
  
  <p>Many thanks!</p>
