java.beans
public interface: Visibility [javadoc |
source]
All Known Implementing Classes:
BeanContextServices, BeanContextServicesSupport, BeanContext, BeanContextSupport
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.
