The HardgoodFulfiller class receives the FulfillOrderFragment message and begins the Fulfillment Process for the shipping groups listed within the message. This class is responsible for calling the appropriate pipeline chains.
When a shipping group is shipped, the warehouse notifies the HardgoodFulfiller. The HardgoodFulfiller then calls the appropriate pipeline chain to change the state of the shipping group and items within it and sends a ModifyOrderNotification detailing the changes. For more information on fulfillment pipelines, see the Fulfillment Pipelines section of this chapter.
