API Enhancements to the JavaBeansTM Component API in J2SE 5.0

JavaBeansTM Component API

This document describes changes to the java.beans package that were introduced in version 5.0 of the Java^TM 2 Platform Standard Edition:

• Support for IndexedPropertyChangeEvent
• New Method for Creating a PropertyEditor
• Public Constructors for PropertyEditorSupport

Support for IndexedPropertyChangeEvent

The bugtraq report that corresponds to this change is: 4353056

A new subclass of PropertyChangeEvent named IndexedPropertyChangeEvent has been added to support bound properties that use an index to identify the part of the bean that changed. Also, three methods — all named fireIndexedPropertyChange — have been added to the PropertyChangeSupport utility class to support firing indexed property change events. You can find an example of using indexed property change events in IndexedTest.java.

New Method for Creating a PropertyEditor

The bugtraq report that corresponds to this change is: 4274639

A new method called createPropertyEditor has been added to the PropertyDescriptor class.

Public Constructors for PropertyEditorSupport

The bugtraq report that corresponds to this change is: 4305280

The two PropertyEditorSupport constructors are now public instead of protected, so that PropertyEditorSupport objects can be more easily created and used as delegates. Also, the source object is now exposed by means of new setSource and getSource methods.
