public interface Join
extends QueryElement
A join query element. This is a query element that can appear in the JOIN part of a Query. Typically a join consists of join table and a join condition (SQL) or an association property (HQL). Examples:
// SQL
SELECT hw.* 
FROM Hardware hw
JOIN HardwareTypes hwt ON hw.hardwaretype_id = hwt.id

// HQL
SELECT hw 
FROM HardwareData hw
JOIN hw.hardwareType hwt

Joins for HQL can be created by the Hql factory class.
