Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences.

interface Visibility

All Known Subinterfaces:: BeanContext

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.

Method Summary
`boolean`	`avoidingGui()` Determines whether this bean is avoiding using a GUI.
`void`	`dontUseGui()` This method instructs the bean that it should not use the Gui.
`boolean`	`needsGui()` Determines whether this bean needs a GUI.
`void`	`okToUseGui()` This method instructs the bean that it is OK to use the Gui.
