Steve Ebersole commented on HHH-4347:
-------------------------------------
Some of tests I'd specifically be interested in seeing:
What happens as you get nested CompositeUserTypes?
What happens as these default columns get too long (especially considering the commonality
is 'toward the front')?
What happens to UserTypes that are not CompositeUserType whose mapping does not define
columns?
etc...
use property names defined in CompositeUserType as default column
names

Key: HHH-4347
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-4347
Project: Hibernate Core
Issue Type: New Feature
Components: annotations
Reporter: Michael Newcomb
Priority: Minor
Consider:
public class LongitudeLatitude
{
protected double longitude;
protected double latitude;
}
public class LongitudeLatitudeCompositeUserType
implements CompositeUserType
{
public String[] getPropertyNames()
{
return new String[] { "longitude", "latitude" };
}
public Type[] getPropertyTypes()
{
return new Type[] { Hibernate.DOUBLE, Hibernate.DOUBLE };
}
...
}
@Entity
public class Test
{
@Basic(optional = false)
@Type(type = "foo.bar.LongitudeLatitudeCompositeUserType")
@Columns(columns = { @Column(name = "location_longitude"), @Column(name =
"location_latitude") })
protected LongitudeLatitude location;
}
Why does the developer need to specify each column?
I'd really rather let the CompositeUserType take care of that for me. Now, I have to
tie the @Columns to the # of properties in my CompositeUserType AND the order in which
they are defined? This seems to defeat the purpose of having a class (CompositeUserType)
to tell Hibernate how to store it.
Couldn't Hibernate prepend the property name 'location' and '_' to
the front of each property name in the CompositeUserType?
Perhaps (more than likely) I'm doing something wrong, but I get a failure if I do not
specify the columns.
Thanks,
Michael
