[Question] Map nested objects with single mapper

[petromir]

I have the following case:

public class Destination {
   private String destinationText;
   private NestedDestination nestedDestination;
}

public class NestedDestination {
   private String nestedDestinationData;
}

public class Source {
   @JMap(value = "destinationText", classes = Destination.class))
   private String sourceText;
   @JMap(value = "nestedDestination", classes = Destination.class))
   private NestedSource nestedSource;
}

public class NestedSource {
   @JMap(value = "nestedDestinationData", classes = NestedDestination.class))
   private String nestedSourceData;
}

The example above doesn't work due to:

com.googlecode.jmapper.exceptions.JMapperException:
com.googlecode.jmapper.exceptions.ConversionBodyIllegalCodeException: error in static
   conversion: probably is an incompatibility of signature, the expected input fields do not match
   with the real ones, checks the configured class.

I would like to map the nested object automatically using single mapper like:

JMapper<Destination, Source> mapper = new JMapper<>(Destination.class, Source.class);

without the need to create one for each nested object like:

JMapper<NestedDestination, NestedSource> mapper = new JMapper<>(NestedDestination.class, NestedSource.class);

Hi @petromir,
You do not need to create a mapper for each recursion, this is a feature already exists in the framework.
Now I create the test with your code, I'll let you know as soon

[petromir]

Great, waiting for the test.
Do you have an example in the wiki for this case?

[avurro]

I created the test using your classes and configurations but the test does not return errors, sure there is not anything else? however, below the test code:

JMapper<Destination, Source> mapper = new JMapper<>(Destination.class, Source.class);

NestedSource nestedSource = new NestedSource("nestedSourceData");

Source source = new Source();
source.setSourceText("sourceText");
source.setNestedSource(nestedSource);

Destination destination = mapper.getDestination(source);

assertEquals("sourceText", destination.getDestinationText());
assertEquals("nestedSourceData", destination.getNestedDestination().getNestedDestinationData());

[petromir]

Sorry, my mistake. It works as expected! Thanks

[avurro]

@petromir classes attribute isn't mandatory, you could reduce configuration

[petromir]

@avurro Yeah I know but I want to limit it to specific class, if this is the way to do it 😄

[avurro]

it's the right way 👍
