one-to-one to a collection handler instead of one-to-many

Hi all,

Use case:

Code:

interface Parent {
   CollectionManager getChildManager();
}

interface CollectionManager {
   Set getAll();
   Set find(String hqlWhereCondition);
}

interface Children {
  Parent getParent()
}

and here is the table:

Code:

parent (
  id
  name
)

child (
  id
  idparent
  name
)

In fact only Parent and Children are persistent classes and ChildManager is simply a collection manager that allow me to sort and filter or to apply Transformers or any other utility to the objects before to use them.

I need the ChildManager because children can be very much and I cannot implement every search method: so I would like to use "HQL" where as a parameter for ChildManager.Find()

Is there a clean way to do that? Any hint?
