The method is called from a ReadOnlyPermissionSet. |
If a permission of the same type as the added permission already exists in the PermissionSet, the new permission is the union of the existing permission object and the specified permission object. For example, if a permission that implements IUnrestrictedPermission is added to an Unrestricted PermissionSet, the resulting union is the original Unrestricted PermissionSet.
