章節(jié)摘錄

版權(quán)頁：插圖：Let's walk through the sequence diagram shown in Figure 17-11.The Member makeshis or her selections using the on-screen tools provided in the ORDER WINDOW （which isnoted to be an interface class）.The ORDER WINDOW then passes those selections with anitem and quantity specification for each to the Controller class. The CONTROLLER100pSthrough each of the items.The use case says that for each ordered item, the system mustverify product availability.To do that the CONTROLLER sends a message to PRODUCT, callingits calculateQtyInStock method.We may have already identified calculateQtyln Stock asa behavior of PRODUCT and so we can read it right off the class diagram and plug it inhere. If it isn't a behavior already, then we can determine a need for its existence from this sequence diagram and then add it to the class diagram. Why would this behaviorbe assigned to PRODUCT~ We see from Figure 17-11 that PRODUCT has a quantityIn Stock at-tribute, so it is the natural source of this information. PRODUCT returns quantityInStock tothe CONTROLLER.The use case includes verbiage to handle items not in stock, hut we arenot following that scenario.This sequence diagram assumes all items are in stock. Each in-stock item must be added to the order. Should that be a responsibility of MEMBER ORDER or MEMBER ORDERED PRODUCT？We see from Figure 17-12 that MEMBER ORDERhas a composition relationship to MEMBER ORDERED PRODUCT, making MEMBER ORDER responsible for the creation and deletion of instances. So we will have the CONTROLLER pass this message to MEMBER ORDER.As it adds an item, MEMBER ORDER needs to recalculate itstotal. So it calls one of its own methods （calcTotal）.To do this calculation, it needs the extended price （quantity times price） of the new item, so it calls calc ExtPrice of MEMBERORDERED PRODUCT. That calculation needs price information, which is held by PRODUCT.So MEMBER ORDERED PRODUCT Creates an instance of PRODUCT to look up the price.The ex-tended price can then be passed back to MEMBER ORDER, which passes the entire order to the CONTAOLLER. Finally, the CONTROLLER passes the order to the ORDER WINDOW for display. From this we can determine what behaviors should be assigned to what classes and the parameters they will accept and return. Once the behaviors have been identiffed, documented, and associated to specific classes, then the class diagram Can beupdated to include those behaviors in the appropriate classes.
