class Target {

interface TargetItem {}
class TargetItemA implements TargetItem {}
class TargetItemB implements TargetItem {}


class Source {
  List<SourceItem> items;
}

interface SourceItem {}
class SourceItemA implements SourceItem {}
class SourceItemB implements SourceItem {}


@Mapper
interface MyMapper {

  public Target sourceToTarget(Source source); 

  // how to map a collection with polymophic items
  public List<TargetItem> itemsToTarget(List<SourceItem> items);

  public TargetItemA itemAToTarget(SourceItemA item);
