Method Detail

doAction

public void doAction(SaleProcess p,
                     SalesPoint sp)
              throws Throwable

Perform the actual action.

The parameters define the context in which the action is performed:

1. It will always be performed in the context of the Shop. The Shop can be retrieved via Shop.getTheShop().
2. If sp != null, sp will define the SalesPoint that is the context of this action.
3. If p != null, p will define the SaleProcess that is the context of this action.

Note, that virtually any combination of the parameters makes sense.

Parameters:

p - the SaleProcess context of the action.

sp - the SalesPoint context of the action.

Throws:

Throwable - on any error that shall be reported and lead to cancellation of the action.
