Examples of java.beans.Visibility

java.beans.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.

            okToUseGui = false;


            // lets also tell the Children that can that they may not use their GUI's
            synchronized(children) {
                for (Iterator i = children.keySet().iterator(); i.hasNext();) {
                    Visibility v = getChildVisibility(i.next());


                    if (v != null) v.dontUseGui();
               }
            }
        }
