public abstract class IOPosition
extends java.lang.Object
Client usage:
InputOutput io = ...; // store current position of IO IOPosition.Position pos = IOPosition.currentPosition(io); ... // scroll to stored position pos.scrollTo();How to support
IOPosition in own IOProvider implementation:
InputOutput provided by IOProvider has to implement Lookup.Provider
IOPosition and implement its abstract methods
