The naming convention follows the hierarchical property naming convention. An asterisk may appear at the end of the name, following a ".", or by itself, to signify a wildcard match. For example: "java.*" or "*" is valid, "*java" or "a*b" is not valid. <P> The action string (inherited from Permission) is unused. Thus, BasicPermission is commonly used as the base class for "named" permissions (ones that contain a name but no actions list; you either have the named permission or you don't.) Subclasses may implement actions on top of BasicPermission, if desired. <p> <P><P><DL><DT><B>See Also: </B><DD><A HREF="../../java/security/Permission.html"><CODE>Permission</CODE></A>, <A
