  |
  +--java.beans.SimpleBeanInfo

public class SimpleBeanInfo
extends Object
implements BeanInfo
This is a support class to make it easier for people to provide BeanInfo classes.

It defaults to providing "noop" information, and can be selectively overriden to provide more explicit information on chosen topics. When the introspector sees the "noop" values, it will apply low level introspection and design patterns to automatically analyze the target bean.
