It seems Selma does not provide native support to convert an array of BeanSource to an array of BeanDestination
But it works fine from a List<BeanSource> to a List<BeanDestination>.

Code below does not compile:

public class BeanSource {
    private int foo;

    public int getFoo() {
        return this.foo;
    }

    public void setFoo(int foo) {
        this.foo = foo;
    }
}

public class BeanDestination {
    private int foo;

    public int getFoo() {
        return foo;
    }

    public void setFoo(int foo) {
        this.foo = foo;
    }
}

public class ArrayBeanSource {
    private BeanSource beans[];

    public BeanSource[] getBeans() {
        return this.beans;
    }

    public void setBeans(BeanSource beans[]) {
        this.beans = beans;
    }
}

public class ArrayBeanDestination {
    private BeanDestination beans[];

    public BeanDestination[] getBeans() {
        return this.beans;
    }

    public void setBeans(BeanDestination beans[]) {
        this.beans = beans;
    }
}

@Mapper(withIoC = IoC.SPRING)
public interface BeanMapper {

    ArrayBeanDestination asArrayBeanDestination(ArrayBeanSource in);
}

I somehow manage to workaround the problem with an abstract mapper

@Mapper(withIoC = IoC.SPRING)
public abstract class AbstractBeanMapper {

    public abstract BeanDestination asBeanDestination(BeanSource in);

    public abstract ArrayBeanDestination asArrayBeanDestination(ArrayBeanSource in);

    public BeanDestination[] asBeanDestination(BeanSource[] in) {
        if (in == null) {
            return null;
        }
        return Arrays.stream(in).map(this::asBeanDestination).toArray(BeanDestination[]::new);
    }

}

Could it be possible for Selma to handle this natively ?
We do not always have the possibility to change the BeanSource or BeanDestination implemention.
