Class IntBooleanType

java.lang.Object

org.itracker.persistence.dao.IntBooleanType

All Implemented Interfaces:

org.hibernate.usertype.UserType

public final class IntBooleanType
extends Object
implements org.hibernate.usertype.UserType

A Hibernate UserType to map a Java boolean or java.lang.Boolean property to an SQL column of type INT with the values 0 (= false) or 1 (= true).

This is necessary because of the legacy ITracker 2.x database schema which uses INT instead of BOOLEAN or BIT, which aren't supported by all databases (e.g. DB2).
