-
applicablePermissions
public java.util.Set<Permission> applicablePermissions()
Description copied from interface:IResource
Returns the set of Permissions that may be applied to this resource Certain permissions are not applicable to particular types of resources. For instance, it makes no sense to talk about CREATE permission on table, or SELECT on a Role. Here we filter a set of permissions depending on the specific resource they're being applied to. This is necessary because the CQL syntax supports ALL as wildcard, but the set of permissions that should resolve to varies by IResource.- Specified by:
applicablePermissions

- Returns:
- the permissions that may be granted on the specific resource
-
