Given this simplification of my structure:
public class Order
{
public String firstName;
public Optional<PaymentInfo> paymentInfo;
}
public class PaymentInfo
{
public String billingAddress;
public int totalAmount;
}
I want to map to this class:
public class SimpleOrder
{
public string firstName;
public Optional<String> billingAddress;
}
I'm not sure how to only map the billingAddress if the Optional has value. I was thinking something like this:
private static Condition<?, ?> optionalHasValue =
(MappingContext<Optional<PaymentInfo>, String> context)
-> context.getSource().isPresent();
private static class OrderMap extends PropertyMap<Order, SimpleOrder>
{
@Override
protected void configure()
{
map(source.firstName, destination.firstName);
when(optionalHasValue)
.map(source.paymentInfo.get().billingAddress, destination.billingAddress);
}
}
but this fails with error "Cannot map final type java.util.Optional.". I did see this question about mapping Optional but it seemed be about a different issue.
