public class TaxProcessorTaxCalculator
extends GenericService
implements TaxPricingCalculator

Uses the atg.payment.tax package to calculate tax for an order. This class is configured with an atg.payment.tax.TaxProcessor which is passed all of the information it needs to compute tax, e.g. the Amount, Shipping Address, Currency Code, etc. Note: This calc looks at the averagePriceRoundingDecimalPlaces property of PricingTools. As of this writing, DCS does not keep track of which units of a CommerceItem are being shipped to what addresses. Also, the ItemPricingEngine is capable of pricing different units of a CommerceItem differently because of various promotions. These two facts mean that we can't be perfectly sure about the exact amount that is to be taxed. Instead, this calculator takes an average CommerceItem unit price and multiplies it by the number of units in a particular shipping group. All this dividing may potentially leave us with a price that has an infinitely repeating number of decimals. The averagePriceRoundingDecimalPlaces property dictates how to truncate these prices before sending them to the TaxProcessor implementation. This calculator keeps track of any missing money and adds it to one of the totals.

priceTax

            RepositoryItem pPricingModel,
            java.util.Locale pLocale,
            RepositoryItem pProfile,
            java.util.Map pExtraParameters)
              throws PricingException

Tax an order within a context. This implementation consults the configured TaxProcessor for the tax. The steps taken here are:

• create and configure a TaxRequestInfo
• pass the TaxRequestInfo to the TaxProcessor
• interpret the TaxStatus on return
• configure the output TaxPriceInfo with information gleaned from the TaxStatus

NOTE: The algorithm used by this method to determine the tax of the order finds an average price for each item and uses that price in determining the tax on every unit of that item. The reason for this is that there is currently no way to specify which individual units of a CommerceItem belong in which shipping relationship. Additionally, units as small as one of a CommerceItem can be priced differently from other units in the same CommerceItem. These two situations mean that when taxing a CommerceItem, there is no way to know explicitly what the total price of a shipping relationship is. Therefore, an average price is computed for all items, and that price is multiplied by the quantity of the CommerceItem that reside in the current relationship to find the total price of the relationship.

Ideally, we should change a shipping relationship to include an exact specification of which units of a CommerceItem belong to that relationship.

Specified by:

priceTax in interface TaxPricingCalculator

pPriceQuote - TaxPriceInfo representing the tax quote for the order

pOrder - The order to tax

pPricingModels - A Collection of RepositoryItems representing PricingModels

pProfile - The user's profile

pExtraParameters - A Map of extra parameters to be used in the pricing, may be null

Throws:

create a TaxableItem for the input relationship and TaxRequestInfo. This implementation finds the average price of a single unit of the relationship's CommerceItem and uses that price as a basis for determining the total cost of the relationship. This in turn affects the amount of tax on this relationship. Extending classes can override this method to gain finer control over the manner in which units of a CommerceItem are assigned to a CommerceItemRelationship.

Parameters:

pRelationship - the relationship for which a TaxableItem is needed.

pTaxRequestInfo - the TaxRequestInfo object into which the returned TaxableItem will be inserted.

Throws:

PricingException

assignItemTaxAmounts

protected void assignItemTaxAmounts(Order pOrder,
                        TaxPriceInfo pOrderTax,
                        TaxStatus pStatus)
                             throws PricingException

Assign each detail's tax for the given order. This method will assign a tax value for the detail proportional to the details cost compared to the order cost. The calculation also takes into consideration the discount share that the item has received, as well as any manual adjustments (always a negative number as it's an adjustment as opposed to a discount). For example, in its simplest form, if the order is $100, the detail is $20, and the tax is $10: the detail's tax will be $2. This method is used if calculateTaxByShipping is false.

Parameters:

pOrder - The order that was just taxed.

pOrderTax - The orders tax.

pStatus - This is the tax status that was returned from the TaxProcessor. This is currently ignored. If the status were to include the item level tax breakdown, this method could be extended to use that information.

Throws:

PricingException

assignItemTaxAmounts

protected void assignItemTaxAmounts(ShippingGroup pShippingGroup,
                        TaxPriceInfo pTaxPriceInfo,
                        OrderPriceInfo pOrderPrice,
                        OrderPriceInfo pShippingSubtotal,
                        TaxStatus pStatus)
                             throws PricingException

Assign each detail's tax for the given order. This method will assign a tax value for the detail proportional to the details cost compared to the shipping group subtotal. For example, if the shipping subtotal is $100, the detail is $20, and the tax is $10: the detail's tax will be $2. This method is used if calculateTaxByShipping is true.

Parameters:

pShippingGroup - The shipping group whose details will be update

pTaxPriceInfo - The TaxPriceInfo for the shipping group

pOrderPrice - The TaxPriceInfo for the entire order

pShippingSubtotal - The price info containing the subtotal information for the shipping group

pStatus - This is the tax status that was returned from the TaxProcessor. This is currently ignored. If the status were to include the item level tax breakdown, this method could be extended to use that information.

Throws:

PricingException

getRelationshipsToAssignTaxTo

public java.util.List getRelationshipsToAssignTaxTo(ShippingGroup pShippingGroup)

Returns the list of ShippingGroupCommerceItemRelationships that should be assigned tax. By default, this returns all ShippingGroupCommerceItemRelationships within the given shipping group.

Parameters:
