CsvMapper support for JsonView-aware schema generation

[k-brooks]

The schema generation process through introspection by the CsvMapper class is very handy, it would be great if we could provide a view in this process to filter out fields which are irrelevant. This is especially important when outputting headers which one would like to be filtered.

Something as simple as the following would suffice

protected void _addSchemaProperties(
      CsvSchema.Builder builder,
      AnnotationIntrospector intr,
      boolean typed,
      JavaType pojoType,
      NameTransformer unwrapper, Class<?> view)
  {
    if (_nonPojoType(pojoType)) {
      return;
    }

    BeanDescription beanDesc = getSerializationConfig().introspect(pojoType);
    for (BeanPropertyDefinition prop : beanDesc.findProperties()) {
      if (!prop.couldSerialize()) {
        continue;
      }
      Class<?>[] viewArray = prop.findViews();
      if (viewArray != null && viewArray.length > 0 && !Arrays.asList(viewArray).contains(view)) {
        continue;
      }

Hmmh. Interesting. I'll add this on my todo list to investigate for 2.13. And would be happy to get a PR too of course.

[k-brooks]

I will start on this now, PR should be up soon

Looks like this may already exist
#195

Confirmed, already supported - sorry for the unnecessary issue

[cowtowncoder]

lol. And I should have remembered having helper with the earlier PR :)
