It's not quite as elegant as I would have hoped. I only asked because I've
found over the years of using Tap you never know what these guys may have
already built, hoping not to reinvent the wheel. Anyhow, unless the tap
guys have something already built, this ended up being my reusable
solution.
public class ObjectModelFactoryImpl implements ObjectModelFactory {
private final PropertyAccess propertyAccess;
private final ValueEncoderSource valueEncoderSource;
private final ValueLabelProvider<Object> valueLabelProvider;
public ObjectModelFactoryImpl(PropertyAccess propertyAccess,
ValueEncoderSource valueEncoderSource, ValueLabelProvider<Object>
valueLabelProvider) {
this.propertyAccess = propertyAccess;
this.valueEncoderSource = valueEncoderSource;
this.valueLabelProvider = valueLabelProvider;
}
public List<Object> create(List<?> objects, String labelProperty) {
PropertyValueLabelProvider propertyValueLabelProvider = new
PropertyValueLabelProvider(
valueEncoderSource, propertyAccess, labelProperty);
return createSelectModel(objects, propertyValueLabelProvider);
}
private List<Object> createSelectModel(List<?> objects,
ValueLabelProvider<Object> labelProvider) {
final List<Object> options = CollectionFactory.newList();
for (Object object : objects) {
String label = labelProvider.getLabel(object);
options.add(label);
}
return options;
}
}
public interface ObjectModelFactory {
public List<Object> create(List<?> objects, String labelProperty);
}
