Interface CartProcessor

All Superinterfaces:

BusinessObject

All Known Implementing Classes:

BasicCartProcessor

public interface CartProcessor
extends BusinessObject

Interface for business logic methods having to do with a user's cart.

The Struts layer employs an instance implementing CartProcessor when a user adds items to his or her cart or edits items. It is also used to handle processing during checkout.

CartProcessor is similar in intention to OrderProcessor. OrderProcessor contains more generic code relating to orders, while CartProcessor contains code specific to manuipulating a user's cart.

When the application needs to create an instance that implements CartProcessor, BusinessObjectFactory finds the name of the Java class to instantiate from the "cartProcessorImplementer" setting in the appComponents.properties file.

The default "cartProcessorImplementer" is BasicCartProcessor.

Method Detail

processAddItems

java.util.Map processAddItems(java.util.Map parameters)
                              throws java.lang.Exception

Processes a request to add items to a user's cart. If the user's cart has not been initialized, this method initializes it first by calling initializeCart() to create a new instance of Order in the User instance for the user. It then adds an OrderDelivery instance under the Order and OrderItem instances under the OrderDelivery.

This method manages the parsing of incoming parameters that identify the products, quantities, and attribute values of the items to be added. It populates OrderItem objects with the incoming information and then hands off the processing to the processAddItems(Collection) method.

The incoming Map must have the following keys:

• orderProductCodes (aString[] holding the codes of the product(s) to add)
• orderProductQuantities (aString[] holding the quantities of the product(s) to add)
• and orderAttributes (aHashMap holding attribute keys and values, where the attribute keys are in the form of 'productCode|attributeCode')

Parameters:

parameters - A Map representing the items and attributes being added to the user's cart.

Returns:

A Map representing the results of the processing. The Map may have one or more of the following keys related to inventory processing: "lowStockEmails", "missingAttributes", "rejectedOrderItems", "adjustedOrderItems", and "newOOSSKUs".

Throws:

java.lang.Exception

processAddItems

java.util.Map processAddItems(java.util.Collection newOrderItems)
                              throws java.lang.Exception

Given a Collection of initialized OrderItem objects, adds the items to the user's cart. Manages the processing of inventory and discounting, updates the user's cart totals, and manages synchronizing the objects with the database.

Parameters:

newOrderItems - The Collection containing the OrderItem objects to be added to the user's cart.

Returns:

A Map containing information on the results of the processing. The Map may have one or more of the following keys related to inventory processing: "lowStockEmails", "missingAttributes", "rejectedOrderItems", "adjustedOrderItems", and "newOOSSKUs".

Throws:

java.lang.Exception

processQuantities

void processQuantities(java.util.Collection newOrderItems)
                       throws java.lang.Exception

Given a Collection of OrderItems in the user's cart whose quantities have been set, updates the totals and weights of each OrderItem based on the (new) quantity.

Parameters:

newOrderItems - The Collection containing the OrderItem objects whose quantities and totals are to be set.

Throws:

java.lang.Exception

processEditItem

java.util.Map processEditItem(java.util.Map parameters)
                              throws java.lang.Exception

Processes a request to edit a given item in a user's cart. The incoming Map must have the same keys required by processAddItems(Map), plus a key named orderItem, which identifies the order item being edited.

Parameters:

parameters - A Map identifying the item being edited and specifying the item's new properties.

Returns:

A Map containing information on the results of the processing. The Map may have one or more of the following keys related to inventory processing: "lowStockEmails", "missingAttributes", "rejectedOrderItems", "adjustedOrderItems", and "newOOSSKUs".

Throws:

java.lang.Exception

CartItemEditAction

processRemoveItem

java.util.Map processRemoveItem(OrderItem orderItem)
                                throws java.lang.Exception

Removes a given OrderItem from the user's cart, updating the cart totals in the process.

Parameters:

orderItem - The OrderItem being removed.

Throws:

java.lang.Exception

initializeCart

void initializeCart()
                    throws java.lang.Exception

Initializes a user's cart. Creates new instances of Order and OrderDelivery representing a user's cart. Sets the current User object's order property with the newly created Order. Synchronizes the new cart with the database.

Throws:

java.lang.Exception

processCheckoutAddresses

java.util.Map processCheckoutAddresses(java.util.Map parameters)
                                       throws java.lang.Exception

Processes a request to add address information to a user's cart. Originates from the checkout process in the Struts layer.

Parameters:

parameters - A Map representing the address information of the current user.

Throws:

java.lang.Exception

See Also:

CheckoutAction.processCheckoutAddresses(BaseForm)

processOrderComplete

java.util.Map processOrderComplete(java.util.Map parameters)
                                   throws java.lang.Exception

Handles processing at the very end of the checkout process, after payments have been processed. Sets the user's order with a status of "Received" and assigns an order number to the order. The "Received" status is given to all orders that have been successfully completed by the user. In other words, orders whose payments succeeded.

The order number is an integer given to each completed order, starting at the "orderNumberFloor" database setting (whose default is 1,000).

Returns:

A Map representing the results of the processing.

Throws:

java.lang.Exception
