-/**
- ** SimpleBeanInfo is a class you may extend to more easily
- ** provide select information to the Introspector. It
- ** implements all of the methods in BeanInfo by returning
- ** null and forces the Introspector to behave exactly as
- ** if there were no BeanInfo class at all (Introspecting
- ** everything).<P>
- **
- ** Overriding one or two of these functions
- ** to give explicit information on only those things you
- ** wish to give explicit information is perfectly safe,
- ** and even desirable.<P>
- **
- ** See the BeanInfo class for information on what the
- ** various methods actually do.
