XStream explained

XStream is a Java library to serialize objects to XML (or JSON) and back again.

NOTE: Not to confuse with XStream stream processing platform at Meta.

XStream library

XStream uses reflection to discover the structure of the object graph to serialize at run time, and doesn't require modifications to objects. It can serialize internal fields, including private and final, and supports non-public and inner classes.^[1]

Object graph serialization

When serializing an object it serializes the full object graph. Duplicate references encountered in the object-model will be maintained. For example, using the following class CDpackage com.thoughtworks.xstream;public class Cd and add some of these object to a listCd bj = new Cd("basement_jaxx_singles");Cd mr = new Cd("maria rita"); List order = new ArrayList<>;order.add(mr);// adds the same cd twice (two references to the same object)order.add(bj);order.add(bj);

// adds itself (cycle)order.add(order);

XStream xstream = new XStream;xstream.alias("cd", Cd.class);System.out.println(xstream.toXML(order));If the above code is executed with XStream's default relative references mode, it will generate the following XML: maria rita basement_jaxx_singles

XStream is free software, distributed under a permissive, revised BSD-style licence.
