Custom promotion implementations
The promotion introduced in promotion anatomy was a pattern based promotion. If you decide to create a custom implementation that differs significantly from the current model, provide an implementation for the com.ibm.commerce.marketing.promotion.Promotion interface, which is a subclass of XMLizable. The interface definition dictates that the new implementation must provide the same set of basic attributes as our default implementation. However, you have free rein when it comes to how you define the purchase conditions. The default implementation provides a "purchase pattern" based implementation; yours can follow any design as long as the following is observed:
- The purchase condition implements the com.ibm.commerce.marketing.promotion.condition.Condition interface.
- It returns true if the promotion is applicable, false otherwise. When true is returned, the promotion should append one or more PromotionExecutionRecord (depending on how many times this promotion can be applied to the current order) to the PromotionContext using addPromotionExecutionRecord method.
This event has a low frequency, and the customization is similar to the Filter and Adjustment approach, so no more details will be discussed here. A sample
