Starting a resource action on its own

Question

I have heard that it is possible to start a resource action on its own -- ie, not run as a before/after action for any of the normal operations. It makes sense that this can be done but it is not documented.
Can someone please give me an idea of how this can be accomplished?
Thanks,
Allen

Answer 1

     public InvoiceItem(int id, int order, float cost, float quantity, String desc, int task, String dName, int perMverticalID) {
          this.id = id;
          this.order = order;
          this.task = task;
          this.perMverticalID = perMverticalID;
          this.cost = cost;
          this.quantity = quantity;
          this.desc = desc;
          this.dName = dName;
          System.out.println("created invoiceitem: " + cost + ", " + quantity + ", " + amount);
     }
