Method Detail

getItemsFromContainer

protected Collection<I> getItemsFromContainer(@NonNull
                                              @NonNull com.broadleafcommerce.cart.client.domain.Cart container,
                                              @Nullable
                                              com.broadleafcommerce.data.tracking.core.context.ContextInfo context)

Description copied from class: AbstractItemMergingService

Gets the from the item container.

Specified by:

getItemsFromContainer in class AbstractItemMergingService<com.broadleafcommerce.cart.client.domain.Cart,I extends com.broadleafcommerce.cart.client.domain.CartItem>

Parameters:

container - the container to fetch the items from

context - the context of the request

Returns:

the items from the container

isSameItem

protected boolean isSameItem(@NonNull
                             @NonNull com.broadleafcommerce.cart.client.domain.CartItem item1,
                             @NonNull
                             @NonNull com.broadleafcommerce.cart.client.domain.CartItem item2)

Description copied from class: AbstractItemMergingService

Tells if two item instances are actually the same instance. This would typically be determined by something like the item ID. Note that this does NOT indicate that "these items are the same so they should be merged". This is used to prevent creating an item match with itself during an update scenario.

Specified by:

isSameItem in class AbstractItemMergingService<com.broadleafcommerce.cart.client.domain.Cart,I extends com.broadleafcommerce.cart.client.domain.CartItem>

Parameters:

item1 - an item to compare

item2 - another item to compare

Returns:

true if the two items are referring to the same instance

hashMatchingCriteria

protected String hashMatchingCriteria(@NonNull
                                      I item)

Generates a hash for any information on the item that should be used to determine if they represent the same item configuration. This implementation only uses attribute choices, which are product options of type CART_ITEM_ATTRIBUTE or VARIANT_DISTINGUISHING.

Specified by:

hashMatchingCriteria in class AbstractItemMergingService<com.broadleafcommerce.cart.client.domain.Cart,I extends com.broadleafcommerce.cart.client.domain.CartItem>

Parameters:

item - the item to generate a hash for

Returns:

a hashed string of some subset of the items attributes

resolveMergeTypes

protected void resolveMergeTypes(@NonNull
                                 @NonNull List<MergeItemPair<I>> mergeItemPairs,
                                 @Nullable
                                 com.broadleafcommerce.data.tracking.core.context.ContextInfo context)

Description copied from class: AbstractItemMergingService

Determines what merge types should be used for the items and applies it to the merge item pairs.

Specified by:

resolveMergeTypes in class AbstractItemMergingService<com.broadleafcommerce.cart.client.domain.Cart,I extends com.broadleafcommerce.cart.client.domain.CartItem>

Parameters:

mergeItemPairs - the item pairs to resolve the merge types for

doMergeCombine

protected void doMergeCombine(@NonNull
                              @NonNull MergeItemPair<I> itemPair)

Description copied from class: AbstractItemMergingService

Perform the actual combination of two items (quantity change) for the combination merge type.

Specified by:

doMergeCombine in class AbstractItemMergingService<com.broadleafcommerce.cart.client.domain.Cart,I extends com.broadleafcommerce.cart.client.domain.CartItem>

Parameters:

itemPair - the item pair to combine
