The InventoryFulfiller class, which extends the FulfillerSystem, sits above the HardgoodFulfiller and the InStorePickupFulfiller classes. This class reviews each item in each shipping group and uses the InventoryManager to purchase, backorder, preorder or mark the item out of stock. You can extend the InventoryFulfiller by overriding the handleNewMessageType method, which is called whenever an unknown message type is received. For additional information on this class, refer to the ATG Platform API Reference.
