= Domain type system (JPA/SQM)
|
||
|
|
|
||
|
|
The JPA type system is an "unmapped" model, meaning that it has no mapping information -
|
||
|
|
no references to tables, columns, etc. The base contract for Hibernate's extension to the
|
||
|
|
JPA model is `org.hibernate.metamodel.model.domain.DomainType`.
|
||
|
|
|
||
|
|
Hibernate's Semantic Query Model (SQM) is defined in terms of these JPA type extensions,
|
||
|
|
through the `org.hibernate.query.sqm.SqmExpressable` contract allowing parts of the application's
|
||
|
|
domain model to be used as part of an SQM tree.
