Extending mapper made easy

Extending the out-of-the-box mapper is now much easier. Thanks to Guice multibindings you can easily register your own Field Processor which can map a field in a custom way. Below code snippet demonstrate how you can register your own field processor ({{MyCustomFieldProcessor}}) with use of multibinding:

public class CustomProcessorModule implements Module { 
   @Override
   protected void configure() {
      Multibinder<FieldProcessor> multibinder = Multibinder.newSetBinder(binder(), FieldProcessor.class);
      multibinder.addBinding().to(MyCustomFieldProcessor.class);
   }
  
}
