Re: Autoboxing with converters

["Bouschen, Michael" <Mi...@akquinet.de.INVALID>]

Hi Craig,

the spec changes sound good to me.

If we do not like this new functionality inculding auto-boxing and converters, I can add an additional converter IntToStringConverter, that is then used for the int field of PCPoint, etc.
But I think we should support auto-boxing and converters, so I agree with the proposed changes.

Regards Michael


I've reviewed the latest test cases for JDO-709 proposed by Michael. The test cases introduce functionality not yet described by the specification.

So I've added the following to Chapter 6 in the Primitive types section.

Fields and properties of primitive types may use a converter in order to convert values to and from database types. Because of auto-boxing, the converter may be defined to use the Java object type corresponding to the primitive type.

And I've added the following to Chapter 6 in the Immutable Object Class types section.

Fields and properties of immutable object types may use a converter in order to convert values to and from database types.

Craig

I think it would be more work to try to disable auto-boxing since that is a Java language feature.

Cool.
