public class OrderDiscountCalculator
extends DiscountCalculatorService
implements OrderPricingCalculator

Calculates OrderPriceInfos for Orders which the calculator is given. This calculator can either be passed in a MatchingObject via the extra parameters map with key Constants.MATCHING_OBJECT containing the order that qualified for the promotion or it can consult the Qualifier service, looking for the Order to be priced. It calls Qualifier.findQualifyingOrder for this purpose.

If it obtains an Order that qualified then it can determine the discount either via a DiscountStructure object being passed into the calculator via the extra parameters map with key Constants.DISCOUNT_STRUCTURE or by getting the discountType and adjuster properties of the input PricingModel (RepositoryItem).

Deprecated. in favor of adjustShippingGroupSubtotalPriceInfos(String, OrderPriceInfo, Order, Locale, RepositoryItem, Map, Map, Map)

Computes a shippinggroup subtotal based on the type of discount given. The logic is as follows:

• If the discount is a percent off, the percent adjuster is applied to the group's price.
• If the discount is an amount off, the adjuster is divided by the number of groups, and [adjuster/n] is applied to the group price.
• If the discount is a fixed amount, the adjuster is divided by the number of groups, and the group price is set to [adjuster/n]

If functionality other than that described above, this method can be overridden to do that which is necessary. For example, rather than spreading out amount off discounts across all shippingGroups, some implementations might want the first ShippingGroup to get the full benefit of the discount.

Parameters:

pTimesToDiscount - the number of times we should apply the configured discount

pNumberOfGroups - the number of groups in the order, including the one for which this method is computing a subtotal

pGroupSubTotal - is the subtotal that needs adjusting

pAdjuster - is the amount by which to adjust pGroupSubTotal

pDiscountType - the way in which pAdjuster is applied to pGroupSubTotal. May be one of: "Fixed Price", "Amount Off", or "Percent Off".

pOrderId - an ID to associate with this adjustment for error reporting

pOldOrderAmount - the order subtotal before this discount was applied at the order level

pNewOrderAmount - the order subtotal after this discount was applied at the order level

pPricingModel - the order promotion that's being applied

pExtraParameters - the extra parameter map originally passed into the pricing operation.

Returns:

the adjusted subtotal for the input pGroupSubTotal

Throws:

PricingException - if there was a problem computing the group subtotal

Deprecated. in favor of {@link #adjustShippingGroupSubtotalPriceInfos(String, OrderPriceInfo, Order, Locale, RepositoryItem, Map, Map, Map)

These method will iterate through each of the maps in the OrderPriceInfo that contain shipping group subtotal information. These include:

• taxableShippingItemsSubtotalPriceInfos
• nonTaxableShippingItemsSubtotalPriceInfos
• shippingItemsSubtotalPriceInfos

For each of entry in each of these maps, computeGroupSubtotal is called. The amount of the price info in the entry is set to this value, the info is marked discounted, and a new adjustement is added to the info

Parameters:

pOrderSubTotal - The new subtotal of the order

pOldOrderAmount - The previous subtotal of the order

pQualifier - The MatchingObject as returned by Qualifier.evaluateQualifier

pAdjuster - The adjuster of the promotion

pDiscountType - The type of discount being given

pPriceQuote - The order's price info

pOrder - The order that was discounted

pPricingModel - The promotion that changed the price of the order

pExtraParameters - Any extra parameters

Returns:

The new subtotal of the order. This is the sum of the shipping group subtotals and should match pOrderSubTotal

Throws:

PricingException

Deprecated.

Computes a shippinggroup subtotal based on the type of discount given. The logic is as follows:

• If the discount is a percent off, the percent adjuster is applied to the group's price.
• If the discount is an amount off, the adjuster is divided by the number of groups, and [adjuster/n] is applied to the group price.
• If the discount is a fixed amount, the adjuster is divided by the number of groups, and the group price is set to [adjuster/n]

If functionality other than that described above, this method can be overridden to do that which is necessary. For example, rather than spreading out amount off discounts across all shippingGroups, some implementations might want the first ShippingGroup to get the full benefit of the discount.

Parameters:

pTimesToDiscount - the number of times we should apply the configured discount

pNumberOfGroups - the number of groups in the order, including the one for which this method is computing a subtotal

pGroupSubTotal - is the subtotal that needs adjusting

pAdjuster - is the amount by which to adjust pGroupSubTotal

pDiscountType - the way in which pAdjuster is applied to pGroupSubTotal. May be one of: "Fixed Price", "Amount Off", or "Percent Off".

pId - an ID to associate with this adjustment for error reporting

Returns:

the adjusted subtotal for the input pGroupSubTotal

Throws:

PricingException - if there was a problem computing the group subtotal
