Better support for fields nullability by Annotation Processors

[xdmaolei]

public ContentValues mapToContentValues(@NonNull ReplyBean object) {
    ContentValues contentValues = new ContentValues(2);

    if(object.content != null){
        contentValues.put("content", object.content);
    }
    if(object.key!= null){
        contentValues.put("key", object.key);
    }

    return contentValues;
}

First I appreciate your work, I think It will be helpful to check the properties whether they are null, and the properties should be non-primitive

Well, columns may be null in SQLite. But we may add support for Nullability annotations in our annotation processor, will it be ok for you?

Thanks, it'll be OK

Hi, @xdmaolei!
We may add property ignoreNull for annotation processor, but it will be quite difficult to clear this field.
Is it acceptable for your case or do you see a way to clear, except using another put resolver?
