public class MediaInputStream

extends java.io.ObjectInputStream

An ObjectInputStream that can serialize Spans. Normally, Spans are seen as primitive data containers like e.g. Strings; however, while the interface is supposed to be like this, internally they aren't.

Spans cannot be deserialized by normal Java serialization because there would be no context for loading scroll blocks. Spans can, however, be deserialized by using a MediaInputStream instead of Java's ObjectInputStream. The MediaInputStream provides a Mediaserver to the spans which they can load their scrollblocks from. By using a MediaOutputStream, you agree that spans may load their blocks.
