added later).
I would go for a slightly different approach: package your editors as
classes, where each class implements
interface Editor
{
Class get EditableType();
void edit( Object editableTarget );
}
You would cast your generic Object onto the appropriate type inside the
edit() function in each of your editor classes. You would set up a
Map<Class,Editor> to pick the right editor to use for an arbitrary
object using:
map.get(editableTarget.getClass()).edit( editableTarget );
I know I can do an [instanceof ...]
but this requires that you hardcode all type names in the code ahead of
time...
