Interface representing an Access Control List (ACL).
Interface for managing owners of Access Control Lists (ACLs) or ACL configurations. (Note that the Acl interface in the java.security.acl package extends this Owner interface.) The initial owner Principal should be specified as an argument to the constructor of the class implementing this interface.
Adds an owner. Only owners can modify ACL contents. The caller principal must be an owner of the ACL in order to invoke this method. That is, only an owner can add another owner. The initial owner is configured at ACL construction time.
Parameters
caller
Principal!: the principal invoking this method. It must be an owner of the ACL.
owner
Principal!: the owner that should be added to the list of owners.
true if the passed principal is in the list of owners, false if not.
