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