This class is deprecated and subject to removal in a future
version of Java SE. It has been replaced by java.security.Policy
and related classes since 1.2.
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.
Summary
Public methods
addOwner
public abstract boolean addOwner (Principal caller,
Principal owner)
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. |
| Returns |
|---|
boolean |
true if successful, false if owner is already an owner. |
deleteOwner
public abstract boolean deleteOwner (Principal caller,
Principal owner)
Deletes an owner. If this is the last owner in the ACL, an exception is
raised.
The caller principal must be an owner of the ACL in order to invoke
this method.
| Parameters |
|---|
caller |
Principal: the principal invoking this method. It must be an owner
of the ACL. |
owner |
Principal: the owner to be removed from the list of owners. |
| Returns |
|---|
boolean |
true if the owner is removed, false if the owner is not part
of the list of owners. |
| Throws |
|---|
NotOwnerException |
if the caller principal is not an owner
of the ACL. |
LastOwnerException |
if there is only one owner left, so that
deleteOwner would leave the ACL owner-less. |
isOwner
public abstract boolean isOwner (Principal owner)
Returns true if the given principal is an owner of the ACL.
| Parameters |
|---|
owner |
Principal: the principal to be checked to determine whether or not
it is an owner. |
| Returns |
|---|
boolean |
true if the passed principal is in the list of owners, false
if not. |
