Class Overview

Inner class of Container used to provide default support for accessibility. This class is not meant to be used directly by application developers, but is instead meant only to be subclassed by container developers.

The class used to obtain the accessible role for this object, as well as implementing many of the methods in the AccessibleContainer interface.
