All Implemented Interfaces:

OrderTotalInterface

public class ProductDiscount
extends BaseOrderTotalModule
implements OrderTotalInterface

Module that creates an OrderTotal object for applying a percentage discount or an amount discount on a single product normally because of a certain quantity is being purchased. The discount may be applied on prices before or after tax. The promotion may be activated on a product only if:

• The total amount of the order is greater than a minimum amount
• The total number of a single product ordered is greater than a minimum amount

There may be multiple valid promotions applicable for an order. If this is the case, the logic applied is the following: All cumulative promotions are summed into one order total object. Then we loop through the order total objects and choose the one that offers the largest discount.

Constructor

Parameters:

eng - the eng

Throws:

com.workingdogs.village.DataSetException - an unexpected exception due to data in Torque (the database layer)

com.konakart.app.KKException - an unexpected exception from the KonaKart engine

org.apache.torque.TorqueException - an unexpected exception in Torque (the database layer)

Method Detail

setStaticVariables

public void setStaticVariables()
                        throws com.konakart.app.KKException

Sets some static variables during setup

Specified by:

setStaticVariables in interface OrderTotalInterface

Throws:

com.konakart.app.KKException - an unexpected exception from the KonaKart engine

isAvailable

public boolean isAvailable()
                    throws com.konakart.app.KKException

Returns true or false

Specified by:

isAvailable in interface OrderTotalInterface

Returns:

True or False

Throws:

getOrderTotal

public OrderTotal getOrderTotal(Order order,
                                boolean dispPriceWithTax,
                                java.util.Locale locale)
                         throws java.lang.Exception

Create and return an OrderTotal object for the discount amount. *

Custom field usage:

• custom1 = Minimum Order Value
• custom2 = Minimum quantity of a single product
• custom3 = Discount Applied
• custom4 = Percentage discount if set to true
• custom5 = Discount applied to pre-tax value if set to true

If the promotion applies to multiple products, we create an array of order total objects and attach the array to the order total that we return (ot.setOrderTotals(otArray)). The reason for doing this is to get a line item of the order for each discounted product. We still need to populate the order total that we return with the total discount amount because this will be used to compare this promotion with other promotions in order to decide which one to use.

The returned OrderTotal custom attributes are populated as follows:

• custom1 = Product Id
• custom2 = Product SKU
• custom3 = Encoded Product Id containing the product id and ids of the options.

Specified by:

getOrderTotal in interface OrderTotalInterface

Parameters:

order - the order

dispPriceWithTax - the dispPriceWithTax

locale - the locale

Returns:

Returns an OrderTotal object for this module

Throws:

java.lang.Exception - an unexpected exception
