Michael Bouschen updated JDO-756:
---------------------------------
Fix Version/s: (was: JDO 3.2)
> Enhance PK to avoid LongIdentity/StringIdentity dependencies
> ------------------------------------------------------------
>
> Key: JDO-756
> URL: https://issues.apache.org/jira/browse/JDO-756
> Project: JDO
> Issue Type: Improvement
> Reporter: joseaio
> Priority: Major
>
> Please see: JDO Guides : M-N Attributed Relation
> http://www.datanucleus.org/products/accessplatform_3_1/guides/jdo/many_many_attributed/index.html
> public class BusinessRelation{
> · private Customer customer; // PK
> · private Supplier supplier; // PK
> BusinessRelation.PK requires:
> · public LongIdentity customer; // LongIdentity dependency
> · public LongIdentity supplier; // LongIdentity dependency
> In Customer and Supplier classes: the id is long (not LongIdentity)
> · private long id; // PK
>
> I think more convenient enhance BusinessRelation.PK to allow long types (and
> remove LongIdentity/***Identity dependencies):
> BusinessRelation.PK
> · public long customer; // Use long as Customer.id field
> · public long supplier; // Use long as Supplier.id field
> note: the same rule for other basic types (String, Dates, Integer, Long,
> Byte...)
