/**
 * A bean implementor who wishes to provide explicit information about
 * their bean may provide a BeanInfo class that implements this BeanInfo
 * interface and provides explicit information about the methods,
 * properties, events, etc, of their  bean.
 * <p>
 * A bean implementor doesn't need to provide a complete set of
 * explicit information.  You can pick and choose which information
 * you want to provide and the rest will be obtained by automatic
 * analysis using low-level reflection of the bean classes' methods
 * and applying standard design patterns.
 * <p>
 * You get the opportunity to provide lots and lots of different
 * information as part of the various XyZDescriptor classes.  But
 * don't panic, you only really need to provide the minimal core
 * information required by the various constructors.
 * <P>
 * See also the SimpleBeanInfo class which provides a convenient
 * "noop" base class for BeanInfo classes, which you can override
 * for those specific places where you want to return explicit info.
 * <P>
 * To learn about all the behaviour of a bean see the Introspector class.
