Line item representing an applied BonusChoiceDiscount in a LineItemCtnr. This type of line item
can only be created by the B2C Commerce promotions engine when applying a BonusChoiceDiscount.
A BonusDiscountLineItem is basically a placeholder in the cart which entitles a customer to add one or more bonus
products to his basket from a configured list of products. Merchants typically display this type of line item in the
cart by showing the corresponding promotion callout message. They typically provide links to the bonus products that
the customer can choose from. This line item can be removed from the cart but will be re-added each time the
promotions engine re-applies discounts. Merchants may however add custom logic to show/hide this line item since it
just a placeholder and not an actual product line item.
The number of products that a customer is allowed to choose from is determined by getMaxBonusItems(). The
collection of products the customer can choose from is determined by getBonusProducts(). When a customer
chooses a bonus product in the storefront, it is necessary to use the AddBonusProductToBasket pipelet
instead of the usual AddProductToBasket pipelet, in order to associate this BonusDiscountLineItem with
the newly created bonus ProductLineItem. Alternatively, the API method
LineItemCtnr.createBonusProductLineItem(BonusDiscountLineItem, Product, ProductOptionModel, Shipment)
can be used instead. The system does proper validations in order to prevent incorrect or too many bonus products from
being associated with this BonusDiscountLineItem. Once a customer has selected bonus products, the product line items
representing the chosen bonus products can be retrieved with getBonusProductLineItems().
Returns whether the promotion that triggered the creation of this line item uses a rule to determine the list of
bonus products.
If the promotion is rule based, then a ProductSearchModel should be used to return the bonus products the
customer may choose from, as the methods that return lists will return nothing. See getBonusProducts()
Get the list of bonus products which the customer is allowed to choose
from for this discount. This list is configured by a merchant entering a
list of SKUs for the discount. Products which do not exist in the system,
or are offline, or are not assigned to a category in the site catalog are
filtered out. Unavailable (i.e. out-of-stock) products are NOT filtered
out. This allows merchants to display out-of-stock bonus products with
appropriate messaging.
If the promotion which triggered this discount does not exist, or this
promotion is rule based, then this method returns an empty list.
If a returned product is a master product, the customer is entitled to
choose from any variant. If the product is an option product, the
customer is entitled to choose any value for each option. Since the
promotions engine does not touch the value of the product option line
items, it is the responsibility of custom code to set option prices.
Get the effective price for the passed bonus product. This is expected to
be one of the products returned by getBonusProducts() with one
exception: If a master product is configured as a bonus product, this
implies that a customer may choose from any of its variants. In this
case, it is allowed to pass in a variant to this method and a price will
be returned. If the passed product is not a valid bonus product, this
method throws an exception.
Parameters:
product - The bonus product to retrieve a price for, must not be null.
Returns:
The price of the passed bonus product as a Number.

If a returned product is a master product, the customer is entitled to
choose from any variant. If the product is an option product, the
customer is entitled to choose any value for each option. Since the

An ordered list of bonus products that the customer may choose
from for this discount.
Returns whether the promotion that triggered the creation of this line item uses a rule to determine the list of
bonus products.

creation of this line item uses a rule to determine the bonus products to choose from.
