# Class java.beans.SimpleBeanInfo

    java.lang.Object
       |
       +----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.

##

SimpleBeanInfo()

##

getAdditionalBeanInfo()
  Claim there are no other relevant BeanInfo objects.

getBeanDescriptor

     public BeanDescriptor getBeanDescriptor()

  Deny knowledge about the class and customizer of the bean. You can override this if you wish to provide explicit info.

getPropertyDescriptors

     public EventSetDescriptor[] getEventSetDescriptors()

  Deny knowledge of event sets. You can override this if you wish to provide explicit event set info.

getDefaultEventIndex

     public int getDefaultEventIndex()

  Deny knowledge of a default event. You can override this if you wish to define a default event for the bean.

getMethodDescriptors

     public MethodDescriptor[] getMethodDescriptors()

  Deny knowledge of methods. You can override this if you wish to provide explicit method info.

getAdditionalBeanInfo

     public BeanInfo[] getAdditionalBeanInfo()

  Claim there are no other relevant BeanInfo objects. You may override this if you want to (for example) return a BeanInfo for a base class.

  Claim there are no icons available. You can override this if you want to provide icons for your bean.

loadImage

     public Image loadImage(String resourceName)

  Parameters:
    resourceName - A pathname relative to the directory holding the class file of the current class. For example, "wombat.gif".
