- * The AccessibleValue interface should be supported by any object

- * provides the standard mechanism for an assistive technology to determine
- * and set the numerical value as well as get the minimum and maximum values.
- * Applications can determine
- * if an object supports the AccessibleValue interface by first
- * obtaining its AccessibleContext (see
- * <a href="java.awt.accessibility.Accessible.html">Accessible</a>) and
- * then calling the
- * <a href="java.awt.accessibility.AccessibleContext.html#getAccessibleValue">
- * getAccessibleValue</a> method of AccessibleContext. If the return
- * value is not null, the object supports this interface.
