Hello,

I wonder if is there possible to use custom collection (instead of hibernate's built-in: set, map, etc.) in one-to-many association. As far as i understand I should use CompositeUserType - but I have no idea how to incorporate my new type into mapping file and one-to-many relation. For exaple suppose we have custom collection

public class FooVector {

// vector of Foos - it does not
// inherite after java Vector.

}

And we have Bar entity,

public class Bar {
private FooVect foos;
}

how can I express one-to-many relation in this case? Member foos is not
a regular property, so i can't use <property> (even if could) so what I can use with my custom FooVectorType?

Any hints?

CompositeUserType is used to map a single type into several columns. Not to create your own collection.

I don't know an easy way to do this. Probably something like creating your own CollectionPersister, but I am mostly certain this won't work too.

We use CERN Colt library for out optmization algo, 'cause Collections are tooooo slow. To solve persistency and mapping problem, we copy from them on get and save on them on set.
This solved our problems, but be careful with lazy mappings.
Ciao.
