How to map collections in Dozer

Question

I\'d like to do something like:

ArrayList objects = new ArrayList();
...
DozerBeanMapper MAPPER = new DozerBeanMapper         


        

Answer 1

You can implement your own mapper class which will extend dozer mapper. Example: Create a interface that adds additional method to dozer mapper:

public interface Mapper extends org.dozer.Mapper {
     List mapAsList(Iterable sources, Class destinationClass);
}

Next step: Write your own Mapper class by implementing above interface.

add below method to your implementation class:

public class MyMapper implements Mapper {
    @Override
    public  List mapAsList(Iterable sources, Class destinationClass) {
        //can add validation methods to check if the object is iterable
        ArrayList targets = new ArrayList();
        for (Object source : sources) {
            targets.add(map(source, destinationClass));
        }
        return targets;
    }
    //other overridden methods.
}

Hope this helps
