Build Status

// Define abstract value type using interface, abstract class or annotation
@Value.Immutable
public interface ValueObject extend WithValueObject {
  // extend not-yet-generated WithValueObject to inherit `with*` method signatures
  String getName();
  List<Integer> getCounts();
  Optional<String> getDescription();

  class Builder extends ImmutableValueObject.Builder {}
  // ImmutableValueObject.Builder will be generated and
  // our builder will inherit and reexport methods as it's own
}

// Use generated immutable implementation and builder
ValueObject v =
    new ValueObject.Builder()
        .name("Nameless")
        .description("present")
        .addCounts(1)
        .addCounts(2)
        .build();

v = v.withName("Doe");
