This interface is called during the update traversal.
If a trait needs to modify the update state of its children, it needs to implement this interface. There is no need to call the Super to forward the call down the trait stack as the update traversal takes care of it.
If this interface is not implemented, the IHierarchy interface will be used to retrieve and queue the children with the same update state as the owning trait.
