Class HibernateTypeFactory

java.lang.Object

org.sqlproc.engine.hibernate.type.HibernateTypeFactory

All Implemented Interfaces:

SqlTypeFactory

public class HibernateTypeFactory
extends Object
implements SqlTypeFactory

The factory definition for the Hibernate stack, which can be used to construct the SqlMetaType instances. In the process of the META SQL statements and mapping rules parsing the input/output values META types have to be established. For this purpose a factory class responsible for these META types construction has to be supplied.
The implementation is based on the Singleton design pattern.
