Type Parameters:

I - The generic ID type.

All Implemented Interfaces:

Serializable, Comparable<BaseEntity<I>>, Identifiable<I>, Timestamped, Versioned

@MappedSuperclass
public abstract class VersionedEntity<I extends Comparable<I> & Serializable>
extends TimestampedEntity<I>
implements Versioned

Mapped superclass for versioned entity. It extends from TimestampedEntity which in turn extends from GeneratedIdEntity. In addition to the "id", "created" and "lastModified" columns, it specifies a Version column, named "version". On pre persist, JPA will automatically set version to 0. On pre update, JPA will automatically increment version with 1.
