public class: SimpleBeanInfo [javadoc | source]

java.lang.Object
   java.beans.SimpleBeanInfo

All Implemented Interfaces:
    BeanInfo

Direct Known Subclasses:
    GenericBeanInfo, StandardBeanInfo, SwingBeanInfoBase

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.

Method from java.beans.SimpleBeanInfo Summary:
getAdditionalBeanInfo,   getBeanDescriptor,   getDefaultEventIndex,   getDefaultPropertyIndex,   getEventSetDescriptors,   getIcon,   getMethodDescriptors,   getPropertyDescriptors,   loadImage

Methods from java.lang.Object:
clone,   equals,   finalize,   getClass,   hashCode,   notify,   notifyAll,   toString,   wait,   wait,   wait

Method from java.beans.SimpleBeanInfo Detail:
public BeanInfo[] getAdditionalBeanInfo() { return null; } 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.
public BeanDescriptor getBeanDescriptor() { return null; } Deny knowledge about the class and customizer of the bean. You can override this if you wish to provide explicit info.
public int getDefaultEventIndex() { return -1; } Deny knowledge of a default event. You can override this if you wish to define a default event for the bean.
public int getDefaultPropertyIndex() { return -1; } Deny knowledge of a default property. You can override this if you wish to define a default property for the bean.
public EventSetDescriptor[] getEventSetDescriptors() { return null; } Deny knowledge of event sets. You can override this if you wish to provide explicit event set info.
public Image getIcon(int iconKind) { return null; } Claim there are no icons available. You can override this if you want to provide icons for your bean.
public MethodDescriptor[] getMethodDescriptors() { return null; } Deny knowledge of methods. You can override this if you wish to provide explicit method info.
public PropertyDescriptor[] getPropertyDescriptors() { return null; } Deny knowledge of properties. You can override this if you wish to provide explicit property info.
public Image loadImage(String resourceName) { try { final Class c = getClass(); java.awt.image.ImageProducer ip = (java.awt.image.ImageProducer) java.security.AccessController.doPrivileged( new java.security.PrivilegedAction() { public Object run() { java.net.URL url; if ((url = c.getResource(resourceName)) == null) { return null; } else { try { return url.getContent(); } catch (java.io.IOException ioe) { return null; } } } }); if (ip == null) return null; java.awt.Toolkit tk = java.awt.Toolkit.getDefaultToolkit(); return tk.createImage(ip); } catch (Exception ex) { return null; } } This is a utility method to help in loading icon images. It takes the name of a resource file associated with the current object's class file and loads an image object from that file. Typically images will be GIFs.
