[jboss-user] [EJB 3.0] - Re: Computed Columns in Entities

[eiben]

Hmm, I was afraid someone would suggest something like this.

Well I could also do something like

  | public int getItemsCount()
  | {
  |   this.getOrderitems().size();
  | }
  | 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 ...
