Change default implementation

When working with the Optimizely Customized Commerce order system, update the dependency container to replace implementations to use your new classes. See Dependency injection for information.

Class	Description
IOrderRepository	The default implementation for IOrderRepository is architected so that it does not need to be replaced to provide custom implementations for different order types. Instead, register implementations for ICartProvider, IPurchaseOrderProvider, and IPaymentPlanProvider to change the behavior of IOrderRepository.
IOrderEvents	Listen to and act on order repository events.
ICartProvider	Change the default implementation of loading and persistence of shopping carts.
IPurchaseOrderProvider	Change the default implementation of loading and persistence of purchase orders.
IPaymentPlanProvider	Change the default implementation of loading and persistence of payment plans.
IOrderGroupFactory	Create implementations of the order system object abstractions. You almost certainly need to change the default implementation if you create a custom order provider, which uses different objects for persistence.
IOrderGroupBuilder	Create sub-components of an order group object abstraction. Each builder is registered to create sub-components for specified types of IOrderGroup. If you create a custom order group, you might need to create a custom order group builder as well, which is registered for the custom group type.
IFulfillmentWarehouseProcessor	Determine a shipment's default warehouse. You need to change the default implementation if you have multiple fulfillment warehouses, because the default implementation only supports one fulfillment warehouse.
IInventoryProcessor	Adjust inventory. You need to change the default implementation if you integrate with another system for inventory checks.
ILineItemValidator	Determine if a line item is valid in terms of active status and availability dates on the entry itself and the catalog. You need to change the default implementation if you have other criteria that determine if a line item is valid.
IPlacedPriceProcessor	Get the currently-placed price for an line item, and update it if necessary. You need to change the default implementation if you have additional pricing rules outside of what is implemented in the configured pricing provider.
IPaymentProcessor	Process payments on an order. You need to change the default implementation if you are not using configured payment providers to handle payments.
