Class JoinFilter

java.lang.Object
  com.vaadin.data.util.filter.AbstractJunctionFilter
      com.vaadin.addon.jpacontainer.filter.JoinFilter

All Implemented Interfaces:

com.vaadin.data.Container.Filter, Serializable

public class JoinFilter
extends com.vaadin.data.util.filter.AbstractJunctionFilter

This filter allows you to implement filtering on joined tables using Hibernate, which lacks support for automatic joins. EclipseLink supports automatic joins, which allows you to filter by e.g. new Equal("skills.skill", s), while Hibernate requires you to do the same using this filter e.g. new JoinFilter("skills", new Equal("skill", s))
