org.hibernate.metamodel.relational

Class PrimaryKey

java.lang.Object

org.hibernate.metamodel.relational.AbstractConstraint

org.hibernate.metamodel.relational.PrimaryKey

All Implemented Interfaces:

Constraint, Exportable

public class PrimaryKey
extends AbstractConstraint
implements Constraint, Exportable

Models a table's primary key.

NOTE : This need not be a physical primary key; we just mean a column or columns which uniquely identify rows in the table. Of course it is recommended to define proper integrity constraints, including primary keys.
