You can just create an instance of SelectModelImpl. To simplify things a
bit, I've just implemented the interface and delegated to a SelectModelImpl
instance.
public class ProductTypeSelectModel implements SelectModel
{
private final SelectModel model;
public ProductTypeSelectModel(final ObjectContext context)
{
final List<OptionModel> options = new ArrayList<OptionModel>();
final SelectQuery query = new SelectQuery(ProductType.class);
query.addOrdering(ProductType.NAME_PROPERTY, true);
final List<ProductType> productTypes = (List<ProductType>)
context.performQuery(query);
options.add(new OptionModelImpl("None (root level)", false, null));
for (final ProductType pt : productTypes)
{
options.add(new OptionModelImpl(pt.getName(), false, pt));
}
model = new SelectModelImpl(null, options);
}
public List<OptionGroupModel> getOptionGroups()
{
return model.getOptionGroups();
}
public List<OptionModel> getOptions()
{
return model.getOptions();
}
public void visit(final SelectModelVisitor visitor)
{
model.visit(visitor);
}
}
This example uses Cayenne to query for my "product_types" and sorts them by
name. Even if you're not familiar with Cayenne, it should be fairly
straightforward.
