Hi,

I have class with a two-dimensional array of booleans as a member.
How do I do I the O/R - mapping in Hibernate for this?

Basically, I would like to to have a table that looks like this:


Row Column Value
1 1 true
1 2 false
1 3 true
2 1 true
2 2 false
2 3 true
.
.
.

I know that I could use the "serializable" type for this, but then
the array is not readable in the database.

Another approach would be to have a set instead of a two-dim.
array. This set consists of Entry-Objects and every object has members
"row", "column" and "value". But for performance reasons I would like
to keep the 2-dim. array.

There is no easy way. It's not doable as a primary feature.

So, what's the complicated way?

Bernd

Don't know about your specific perf reasons, but you may map it as a map or a set and build a non mapped 2 dim array in your java code.

Ok, that was my idea as well.
Thanks for your quick help.
