@GeneratePojoBuilder and inheritance-depth

[flexguse]

Hi,

first of all thanks a lot for PojoBuilder, it helps me a lot in by day-to-day business.

Currently I'm setting up a new project using pojo-builder in version 3.4.0 and Java 1.8 with a multi inheritance object modeling like

public abstract class AbstractEntity{}

public abstract class LocalizedEntity extends AbstractEntity{}

public abstract class CatalogEntity extends LocalizedEntity{}

@GeneratePojoBuilder
public class Article extends CatalogEntity{}

The generated builder for Article (ArticleBuilder) only includes the attributes of CatalogEntity but not of LocalizedEntity or AbstractEntity.

Did I miss something in the configuration? Is this maybe not a feature of PojoBuilder? Has this question asked a hundret times and I'm not able to find the answer?

Please help!

Thank you in advance, Christoph

Christoph,

PB is perfectly fine with inheritance hierarchies. Just make sure, that PB has write access to all properties of your pojo.

For example, place the @GeneratePojoBuilder above the pojo's constructor if it has parameters, instead of placing it above the class declaration.

Here is a working example:

public class AbstractEntity<ID> {
  private ID id;
  private DateTime created;

  public AbstractEntity(ID id, DateTime created) {
    this.id = id;
    this.created = created;
  }

  public ID getId() {
    return id;
  }

  public DateTime getCreated() {
    return created;
  }
}

public class Product extends AbstractEntity<Long> {

  private String name;

  @GeneratePojoBuilder
  public Product(Long id, DateTime created) {
    super(id, created);
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }
}

public class ProductBuilderTest {

  @Test
  public void testBuild() {
    // Given:
    Long id = Long.valueOf(1);
    DateTime dateTime = DateTime.now();
    String name = "xyz";
    ProductBuilder underTest = new ProductBuilder();

    // When:
    Product actual = underTest.withId(id).withCreated(dateTime).withName(name).build();

    // Then:
    assertThat(actual.getId()).isEqualTo(id);
    assertThat(actual.getCreated()).isEqualTo(dateTime);
    assertThat(actual.getName()).isEqualTo(name);
  }
}
