Interface Decorator

public interface Decorator

A simple wrap/unwrap interface that can be used to decorate properties when using databinding.

2 Operations allow conversion from and to the backing model bean's property.

The property name used for data binding is also passed in to allow a Screen to simple implement this interface, in order to keep decoration encapsulated in the Screen class.
