This class stores an arbitrary collection of Permission objects. When Permission objects are added with the add( ) method, they are grouped into an internal set of PermissionCollection objects that contain only a single type of Permission. Use the elements( ) method to obtain an Enumeration of the Permission objects in the collection. Use implies( ) to determine if a specified Permission is implied by any of the Permission objects in the collection. Permissions is used by system code that manages security policies. Applications rarely need to use it.
