## 23.20 java.beans.SimpleBeanInfo (JDK 1.1)

###

The `SimpleBeanInfo` class is a trivial implementation of the `BeanInfo` interface. The methods of this class all return `null` or `-1`, indicating that no bean information is available. To use this class, you need only to override the method or methods that return the particular type of bean information you want to provide.

In addition, `SimpleBeanInfo` provides a convenience method, `loadImage()`, that takes a resource name as an argument and returns an `Image object`. This method is useful when defining the `getIcon()` method.

    public class SimpleBeanInfo extends Object implements BeanInfo {
        // Default Constructor: public SimpleBeanInfo()
        // Public Instance Methods
                public BeanInfo[] getAdditionalBeanInfo();  // From BeanInfo
                public BeanDescriptor getBeanDescriptor();  // From BeanInfo
                public int getDefaultEventIndex();  // From BeanInfo
                public int getDefaultPropertyIndex();  // From BeanInfo
                public EventSetDescriptor[] getEventSetDescriptors();  // From BeanInfo
                public Image getIcon(int iconKind);  // From BeanInfo
                public MethodDescriptor[] getMethodDescriptors();  // From BeanInfo
                public PropertyDescriptor[] getPropertyDescriptors();  // From BeanInfo
                public Image loadImage(String resourceName);
    }
