java.security.acl.Group |
Known Indirect Subclasses |
This interface is used to represent a group of principals. (A principal represents an entity such as an individual user or a company).
Note that Group extends Principal. Thus, either a Principal or a Group can
be passed as an argument to methods containing a Principal parameter. For
example, you can add either a Principal or a Group to a Group object by
calling the object's addMember
method, passing it the
Principal or Group.
