Method Details
-
calculateTotals
performs a (re)calculation on the given abstractOrderRao and updates these properties:- Parameters:
abstractOrderRao- the abstractOrderRao to calculate
-
addOrderLevelDiscount
Creates a new order level discount based on the given values, adds it to the cartRao and updates the cartRao totals. If theabsoluteflag is set to true, the discount is absolute, otherwise its a percentage based discount.- Parameters:
cartRao- the cartRao to add the discount toabsolute- whether the discount is absolute or percentage-basedamount- the amount of the discount- Returns:
- the created DiscountRAO
-
addOrderEntryLevelDiscount
DiscountRAO addOrderEntryLevelDiscount(OrderEntryRAO orderEntryRao, boolean absolute, BigDecimal amount) Creates a new order entry level discount based on the given values, adds it to the corresponding orderRao and updates the orderRao totals. If theabsoluteflag is set to true, the discount is absolute, otherwise its a percentage based discount.- Parameters:
orderEntryRao- the orderEntryRao to add the discount toabsolute- whether the discount is absolute or percentage-basedamount- the amount of the discount- Returns:
- the created DiscountRAO
-
addOrderEntryLevelDiscount
default Set<DiscountRAO> addOrderEntryLevelDiscount(OrderEntryRAO orderEntryRAO, boolean absolute, BigDecimal amount, boolean perUnit) Create a set of order entry level discounts based on the given value, absolute flag and perUnit flag, adds it to the corresponding orderRao and updates the orderRao totals. If theabsoluteflag is set to true, the discount is absolute, otherwise it's a percentage based discount. If theperUnitflag is set to true, it means give discount on each product of order entry, If theperUnitflag is set to false, it means give discount to the whole order entry- Parameters:
orderEntryRAO- the orderEntryRao to add the discount toabsolute- whether the discount is absolute or percentage-basedamount- the amount of the discountperUnit- whether the discount is given to each product of order entry or the whole order entry- Returns:
- the created DiscountRAO set
-
changeDeliveryMode
Changes the current delivery mode to the given values, adds it to the cartRao and updates the carRao totals.- Parameters:
cartRAO- the cartRao to change the delivery mode fordeliveryModeRAO- the new delivery mode- Returns:
- the ShipmentRAO
-
addFreeProductsToCart
Adds free product items to the cart.- Parameters:
cartRao- cart where to add the productproduct- a product to addquantity- quantity of product items to add- Returns:
- FreeProductRAO the free product to be given
-
addFixedPriceEntryDiscount
Creates a new order entry level discount such that the order entry's price will be equal to the givenfixedPricemultiplied by quantity.- Parameters:
orderEntryRao- the orderEntryRao to add the discount tofixedPrice- the target unit price- Returns:
- the created DiscountRAO
-
getCurrentPrice
BigDecimal getCurrentPrice(Set<OrderEntryRAO> orderEntryForDiscounts, Map<Integer, Integer> discountedOrderEntryMap) Calculates current price of the set of Order Entries using only specified quantity of units for every Order Entry.- Parameters:
orderEntryForDiscounts- set with Order Entries which price need to be calculateddiscountedOrderEntryMap- Map having orderEntry.entryNumber as keys and Unit Quantity To Be Consumed as values- Returns:
- BigDecimal current price
-
addFixedPriceEntriesDiscount
List<DiscountRAO> addFixedPriceEntriesDiscount(CartRAO cartRao, Map<Integer, Integer> selectedOrderEntryMap, Set<OrderEntryRAO> selectedOrderEntryRaos, BigDecimal fixedPrice) Creates order entry level discounts for the cartcartRao, with thefixedPricegiven as parameter and for the products from entries inselectedOrderEntryRaosand related quantities given inselectedOrderEntryMap.- Parameters:
cartRao- Cart RAO used for totals calculationsselectedOrderEntryMap- Map having orderEntry.entryNumber as keys and unit quantity to be consumed as valuesselectedOrderEntryRaos- Order entries to be discountedfixedPrice- Target price for discounted product- Returns:
