public interface AccessibleValue
The 
AccessibleValue interface should be supported by any object that
 supports a numerical value (e.g., a scroll bar). This interface 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 Accessible) and
 then calling the AccessibleContext.getAccessibleValue() method. If the
 return value is not null, the object supports this interface.- See Also:
