|
* A PermissionRole represents a collection of permission codes that can be applied to groups. |
|
12
|
|
|
* |
|
13
|
|
|
* Because permission codes are very granular, this lets website administrators create more |
|
14
|
|
|
* business-oriented units of access control - Roles - and assign those to groups. |
|
15
|
|
|
* |
|
16
|
|
|
* If the <b>OnlyAdminCanApply</b> property is set to TRUE, the role can only be assigned |
|
17
|
|
|
* to new groups by a user with ADMIN privileges. This is a simple way to prevent users |
|
18
|
|
|
* with access to {@link SecurityAdmin} (but no ADMIN privileges) to get themselves ADMIN access |
|
19
|
|
|
* (which might be implied by certain roles). |
