|
|
** 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.
