Class CalculateOrderCmdImpl

  • All Implemented Interfaces:
    com.ibm.commerce.command.CacheableECCommand, ECCommand, ECTargetableCommand, TaskCommand, CalculateOrderCmd, com.ibm.websphere.cache.Sizeable, com.ibm.websphere.command.CacheableCommand, com.ibm.websphere.command.Command, com.ibm.websphere.command.CommandCaller, com.ibm.websphere.command.TargetableCommand, java.io.Serializable

    public class CalculateOrderCmdImpl
extends TaskCommandImpl
implements CalculateOrderCmd
    This is implementation of the CalculateOrderCmd task command.

    Behavior:

    For each Order specified:
    • if doFreeGift is true, free gift handling logic is called.
      • keep the CatalogEntries which are auto added freegiftbefore to iarrAutoAddedOrderItems.
      • if the PromotionsEngine component is enabled and freegift is to be refreshed. Call the PromotionEngine to obtain a list of CatalogEntries to add to the Order
      • for each CatalogEntry to be added to the Order, if ATP is disabled and there is insufficient inventory:
        • remove the CatalogEntry from the list
        • add the CatalogEntry identifier to the outOfInventoryCatalogEntryId list
      • get the list of order items which to be added or updated. If the new CatalogEntries returned from PromotionEngine having same CatetnryId and Quantity, do nothing. If with same CatentryId but different Quantity, add it to updating list. If the CatentryId of this new CatalogEntry is not contained in the existed ones, add it to adding list. If the free gifts which are cached before are not contained in the new returned list, add it to deleting list.
      • call removeFreeGifts method to remove the freegifts listed in the deleting list
      • call updateFreeGiftsQuantities method to update the quantities of freegifts listed in the updating list
        • call resolveATPParameter method to resolve the ATP parameter. In this method, it gets the ATP parameters from requestProperties of CommandContext, the ATP parameters for the freegift include: CHECK, ALLOCATE and BACKORDER.
        • call OrderItemUpdateCmd to update the quantity of the freegift
      • call addFreeGifts method to add the new freegifts listed in the adding list
        • call resolveATPParameter method to resolve the ATP parameter.In this method, it gets the ATP parameters from requestProperties of CommandContext, the ATP parameters for the freegift include: CHECK, ALLOCATE and BACKORDER.
        • call OrderItemAddCmd to add new the freegift
    • compute the product total of order
    • initialize the specified CalculationUsages that are enabled
    • apply the specified CalculationUsages that are enabled
    • update the SubOrders for the Order unless that feature is disabled
    • summarize the specified CalculationUsages that are enabled
