Hmm, I was afraid someone would suggest something like this.
Well I could also do something like
| public int getItemsCount()
| public float getItemTotal()
| float retVal = 0;
| for (Orderitem currentOrder : this.getOrderitems())
| retVal += currentOrder.getQuantity() . currentOrder.getItem().getPrice();
| return retVal;
but I would consider this as sub-optimal, because doing this kind of computation could also be done using the database, and I would say that it would be a little bit faster ...
