Filter on attribute source entity

Hi !

I have an entity like below :

@Table(name = "t_gti_interlocuteur")
public class Interlocuteur extends AbstractEntity{

   …

	@Column(name = "co_entite_liee", length = 3)
	private String codeEntiteLiee;

	@OneToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "id_rcu_entite_liee", referencedColumnName = "id_rcu_tiers", insertable = false, updatable = false, foreignKey = @ForeignKey(name = "none"))
	private Tiers tiers;

}

The entity “Interlocuteur” can be joined to entity “Tiers”. There is no foreign key between these entities (eg @ForeignKey(name = “none”) ).

But the join must be done only if attribute “co_entite_liee” of entity “Interlocteur” is equals to ‘TIE’.

How can I define with annotations this restriction ?

Thanks
