Discriminator with class name value

Mapping documents:

Code:

<class name="com.example.Foo" table="foo">
   <id name="id" column="id"><generator class="native"/></id>

   <discriminator column="type" />

   <subclass discriminator-value="com.example.FooImplSimple"
                            name="com.example.FooImplSimple" />

   <subclass discriminator-value="com.example.FooImplComplex"
                            name="com.example.FooImplComplex" />
</class>

Hello

I have a database table called 'foo' with fields id (int) and type (varchar).
The contents of the table are:
1 - com.example.FooImplSimple
2 - com.example.FooImplComplex

Is there a way to improve the mapping by not having to explicitly bind each string discriminator value with the name of the class? The classname is the value of the field itself.

Thanks,
Ioannis

the class name is the default value for the discriminator so just don't specify it.

WARNING: using the full classname is not without problems...think through what happens the day you decide to refactor your classes and move them into different packages!
