public class AccessibleRole

extends AccessibleBundle

Class AccessibleRole determines the role of a component. The role of a component describes the components generic function, such as "push button," "table," or "list."

The toDisplayString method allows you to obtain the localized string for a locale independent key from a predefined ResourceBundle for the keys defined in this class.

The constants in this class present a strongly typed enumeration of common object roles. A public constructor for this class has been purposely omitted and applications should use one of the constants from this class. If the constants in this class are not sufficient to describe the role of an object, a subclass should be generated from this class and it should provide constants in a similar manner.
