I think I'm missing something simple here.
in the following example of Father and Child (parent-child
relationship)
Father:
<class name="father" table="father" lazy="false">
<!-- identity mapping -->
<id name="ID" unsaved-value="any">
<column name="ID" />
<generator class="native" />
</id>
<bag name="children" cascade="save-update" lazy="false">
<key column="father_id" />
<one-to-many class="child" />
</bag>
</class>
AND Child:
<class name="child" table="child" lazy="false">
<!-- identity mapping -->
<id name="ID" unsaved-value="any">
<column name="ID" />
<generator class="native" />
</id>
<many-to-one name="my_father"
class="father"
column="father_id"
cascade="none" lazy="false" not-null="true"/>
</class>
This mapping says -
A father can have multiple children.
A child can have only one father.
IF the previously defined mapping and constraints are CORRECT -
then my confusion is regarding many-to-any.
That is because many-to-any needs to be within a set element
<set>
<many-to-any ..../>
</set>
which is throwing me off the multiplicity of the association here!
I mean.. I expected it to be like many-to-one ... but with the "one"
part being heterogeneous.
Please help!
thanks.
