AbstractEntity (jpaservices 17.0 API)

java.lang.Object
- org.fryske_akademy.jpa.AbstractEntity

All Implemented Interfaces:

Serializable, EntityInterface
```
@MappedSuperclass
public class AbstractEntity
extends Object
implements EntityInterface
```
superclass for entities, defines auto generated id (GenerationType.IDENTITY), a version column and a function to check if the entity is transient (not in db yet). Jpa annotations are on getters which allows you to override. If you want to annotate fields in your subclasses be sure to annotate with AccessType.FIELD.
