 Post subject: Desiding the type of an Entity Attribute at runtime

I am using MongoDB and Hibernate OGM in my project.

My question is in the entity class (ExampleClass) I should be able to assign "someFeature" attribute a value at runtime that is an instance of either LabelClass or PointClass (i.e. an instance extended from Feature class based on some event). Is this possible if so can a example provided?

Lets say I have the following embeddable and the entity classes.

@Embeddable
@Inheritance(...)
public abstract class Feature{
@Id
protected Long id;



}

@Embeddable
public class LabelClass extends Feature{
protected String str;


}


@Embeddable
public class PointClass extends Feature{
protected Integer intg;


}

@Entity
public class ExampleClass{
private Feature someFeature;


}

Sorry, at the moment I don't think there is a way to do that with OGM.
Inheritance with embeddables is not supported.

You might try to create your own TypeContributor implementation but it can be a bit complicated.
