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

java.lang.Object

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

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

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

Type Parameters:

I - The generic ID type.

All Implemented Interfaces:

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

Direct Known Subclasses:

VersionedEntity

@MappedSuperclass
public abstract class TimestampedEntity<I extends Comparable<I> & Serializable>
extends GeneratedIdEntity<I>
implements Timestamped

Mapped superclass for timestamped entity. It extends from GeneratedIdEntity which in turn extends from BaseEntity. In addition to the "id" column, it specifies two timestamp columns, named "created" and "lastModified". On pre persist, the both columns will be set to current timestamp. On pre update, the "lastModified" column will be set to current timestamp, unless skipAdjustLastModified() is called beforehand.
