Class ChangeLineItemQuantity

java.lang.Object

io.sphere.sdk.models.Base

io.sphere.sdk.commands.UpdateActionImpl<Cart>

io.sphere.sdk.carts.commands.updateactions.ChangeLineItemQuantity

All Implemented Interfaces:

UpdateAction<Cart>

public final class ChangeLineItemQuantity
extends UpdateActionImpl<Cart>

Sets the quantity of the given line item. If quantity is 0, line item is removed from the cart.
In case of multiple shipping addresses, ChangeLineItemQuantity does not support changing the shipping details like RemoveLineItem and AddLineItem because in the case of not sending the shippingDetails field it would not be clear if the shipping details should be removed at all (possible data loss) or remain unchanged. Use SetLineItemShippingDetails in combination with this update action in one cart update command to change the line item quantity and shipping details altogether.

See also CartInStoreUpdateCommand.

withEmptyCartAndProduct(client(), (cart, product) -> {
    assertThat(cart.getLineItems()).hasSize(0);
    final AddLineItem action = AddLineItem.of(product.getId(), MASTER_VARIANT_ID, 3L);

    final Cart cartWith3 = client().executeBlocking(CartUpdateCommand.of(cart, action));
    final LineItem lineItem = cartWith3.getLineItems().get(0);
    assertThat(lineItem.getQuantity()).isEqualTo(3);

    final Cart cartWith2 = client().executeBlocking(CartUpdateCommand.of(cartWith3, ChangeLineItemQuantity.of(lineItem, 2L)));
    assertThat(cartWith2.getLineItems().get(0).getQuantity()).isEqualTo(2);

    final Cart cartWith0 = client().executeBlocking(CartUpdateCommand.of(cartWith2, ChangeLineItemQuantity.of(lineItem, 0L)));
    assertThat(cartWith0.getLineItems()).hasSize(0);
});
See the test code.
