Package org.omnifaces.persistence.model

Class BaseEntity<I extends Comparable<I> & Serializable>

java.lang.Object

org.omnifaces.persistence.model.BaseEntity<I>

Type Parameters:

I - The generic ID type.

All Implemented Interfaces:

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

Direct Known Subclasses:

GeneratedIdEntity, TimestampedBaseEntity

@MappedSuperclass
public abstract class BaseEntity<I extends Comparable<I> & Serializable>
extends Object
implements Comparable<BaseEntity<I>>, Identifiable<I>, Serializable

Let all your entities extend from this. Then you can make use of BaseEntityService.

There are five more mapped superclasses which may also be of interest.

• TimestampedBaseEntity - extends BaseEntity with created and lastModified columns and automatically takes care of them.
• VersionedBaseEntity - extends TimestampedBaseEntity with a @Version column and automatically takes care of it.
• GeneratedIdEntity - extends BaseEntity with id column and automatically takes care of it.
• TimestampedEntity - extends GeneratedIdEntity with created and lastModified columns and automatically takes care of them.
• VersionedEntity - extends TimestampedEntity with a @Version column and automatically takes care of it.
