org.hibernate.mapping.SimpleValue

org.hibernate.mapping.Component

All Implemented Interfaces:

Serializable, KeyValue, MetaAttributable, SortableValue, Value

public class Component
extends SimpleValue
implements MetaAttributable, SortableValue

A mapping model object that represents an embeddable class.

Serialized Form

"API Note:"

The name of this class is historical and unfortunate. An embeddable class holds a "component" of the state of an entity. It has absolutely nothing to do with modularity in software engineering.
