I have noticed, to represent a
unidirectional one to one
<many-to-one> mapping with unique constraint true is generally being used .
<class name="Person"> <id name="id" column="personId"> <generator class="native"/> </id> <many-to-one name="address" column="addressId" unique="true" not-null="true"/> </class> <class name="Address"> <id name="id" column="addressId"> <generator class="native"/> </id> </class>
Can any body tell me why can't we use the <one-to-one> mapping ? if we can use the aforesaid , could you tell me how can use that ?
Thanks & Regards
