Andy Jefferson commented on JDO-403:
------------------------------------
In addition to the previous addition, please update the provided Field
annotation (in the attached jar) to also include
=====================
/** Name of the field when this is embedded in another object. */
String embeddedFieldName() default "";
=====================
This is for use (only) when the user wants to define the field mapping for
embedded fields. To give an example of its usage
@PersistenceCapable
public class Computer
{
@Field
@Embedded(nullIndicatorColumn="GRAPHICS_MANUFACTURER",
ownerField="computer",
fields={
@Field(embeddedFieldName="manufacturer", [EMAIL
PROTECTED](name="GRAPHICS_MANUFACTURER")}),
@Field(embeddedFieldName="type", [EMAIL
PROTECTED](name="GRAPHICS_TYPE")})
})
private ComputerCard graphicsCard;
}
@PersistenceCapable
public class ComputerCard
{
@Field
private String manufacturer;
@Field
private int type;
}
so we are defining the mapping of the columns of ComputerCard when persisted
into the table for Computer.

> Project: JDO
> Issue Type: New Feature

> Affects Versions: JDO 2 final
> Reporter: Andy Jefferson
> Fix For: JDO 2 maintenance release 1

> Attachments: jdo_2_1_annotations.jar

>
> It would be desirable for JDO2 to have its own set of annotations. We have
> developed a set within JPOX that would likely serve as a starting point for
> such a set. In my opinion they should be
> 1. Split into javax.jdo.annotations.jdo and javax.jdo.annotations.orm
> 2. Move ORM attributes from some of the JDO annotations and have a ORM
> annotation.
