> ---------------------------------
>
> Key: HIB-204
> URL: http://jira.andromda.org/browse/HIB-204
> Project: Hibernate Cartridge
> Type: New Feature
> Reporter: Franco Caponi
> Assignee: Wouter Zoons

> Hibernate documentation say that is possible using the formula attribute of
> the discriminator tag, but AndroMDA doesn't implement this feature.
> From Hibernate documentation:
> [QUOTE]
> The <discriminator> element is required for polymorphic persistence using the
> table-per-class-hierarchy mapping strategy and declares a discriminator
> column of the table. The discriminator column contains marker values that
> tell the persistence layer what subclass to instantiate for a particular row.
> A restricted set of types may be used: string, character, integer, byte,
> short, boolean, yes_no, true_false.
> <discriminator
> column="discriminator_column" (1)
> type="discriminator_type" (2)
> force="true|false" (3)
> insert="true|false" (4)
> formula="arbitrary sql expression" (5)
> />
> [/QUOTE]
