SimpleBeanInfo (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

java.lang.Object
  java.beans.SimpleBeanInfo

All Implemented Interfaces:: BeanInfo

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.

Constructor Summary
`SimpleBeanInfo()`

Method Summary
`BeanInfo[]`	`getAdditionalBeanInfo()` Claim there are no other relevant BeanInfo objects.
`BeanDescriptor`	`getBeanDescriptor()` Deny knowledge about the class and customizer of the bean.
`int`	`getDefaultEventIndex()` Deny knowledge of a default event.
`int`	`getDefaultPropertyIndex()` Deny knowledge of a default property.
`EventSetDescriptor[]`	`getEventSetDescriptors()` Deny knowledge of event sets.
`Image`	`getIcon(int iconKind)` Claim there are no icons available.
`MethodDescriptor[]`	`getMethodDescriptors()` Deny knowledge of methods.
`PropertyDescriptor[]`	`getPropertyDescriptors()` Deny knowledge of properties.
`Image`	`loadImage(String resourceName)` This is a utility method to help in loading icon images.

Method Detail

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.

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.

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.

getDefaultPropertyIndex

public int getDefaultPropertyIndex()

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

getEventSetDescriptors

public EventSetDescriptor[] getEventSetDescriptors()

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

getIcon

public Image getIcon(int iconKind)

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

Parameters:: iconKind

getMethodDescriptors

public MethodDescriptor[] getMethodDescriptors()

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

getPropertyDescriptors

public PropertyDescriptor[] getPropertyDescriptors()

Deny knowledge of properties. You can override this if you wish to provide explicit property info.

loadImage

public Image loadImage(String resourceName)

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.

Parameters:: resourceName - A pathname relative to the directory holding the class file of the current class. For example, "wombat.gif".
Returns:: an image object. May be null if the load failed.
