Method Detail

addOrderLevelDiscount

DiscountRAO addOrderLevelDiscount(CartRAO cartRao,
                                  boolean absolute,
                                  java.math.BigDecimal amount,
                                  RuleEngineResultRAO result,
                                  java.lang.Object ruleContext)

Adds an order level discount to the given cartRao, recalculates the cart totals and returns the discount. The absolute flag determines whether the discount is absolute or percentage based. For absolute values, the cart's currency is used. The amount specifies the amount used, e.g. $20 or 10%. The ruleContext can be used to enhance the returned DiscountRAO.

Parameters:

cartRao - the CartRAO to apply the discount to

absolute - the type of discount

amount - the amount of the discount

result - the result rao

ruleContext - an optional context object that can be used to provide additional information for the returned DiscountRAO

addOrderLevelDiscount

DiscountRAO addOrderLevelDiscount(CartRAO cartRao,
                                  boolean absolute,
                                  java.math.BigDecimal amount,
                                  java.lang.String[] excludedProducts,
                                  RuleEngineResultRAO result,
                                  java.lang.Object ruleContext)

Adds an order-level discount to the cartRao and recalculates cart totals. Takes into account the excluded products so that non-absolute discounts are calculated relative to the total excluding these products

Parameters:

cartRao - Cart to apply the discount to.

absolute - true if the discount is a definite currency amount, rather than a percentage discount

amount - currency amount or percentage to be discounted

result - resultRAO containing information from evaluation action

ruleContext - additional info for the rule execution environment

Returns:

order-level DiscountRAO

calculateSubTotals

java.math.BigDecimal calculateSubTotals(CartRAO cartRao,
                                        java.lang.String[] excludedProductCodes)

Calculates the cart sub total for CartRao excluding a set of products.

Parameters:

cartRao - CartRAO object to be calculated

excludedProductCodes - Array of product codes that identify cart entries to be excluded

Returns:

result of the cartSubTotals (without charges like payment or delivery) minus the excluded products
