    public interface Visibility
    Under some circumstances a bean may be run on servers where a GUI is not available. This interface can be used to query a bean to determine whether it absolutely needs a gui, and to advise the bean whether a GUI is available.

    This interface is for expert developers, and is not needed for normal simple beans. To avoid confusing end-users we avoid using getXXX setXXX design patterns for these methods.
