I have a related follow-up question. I was getting a stack overflow at
runtime because of the polymorphic hierarchy and was not using @ExtraTypes.
My hierarchy was 3 levels deep. Top level is GenericType, next level is
CategoryType and EventType, and next level is four subtypes of CategoryType
and 4 subtypes of EventType.
I finally got it working by putting @ExtryTypes in my request factory. It
only worked when I put the @ExtraTypes with the full list of 10 types above
GenericType. Initially I had tried to put @ExtraTypes with just 2 types
above GenericType and @ExtraTypes with 4 types each above CategoryType and
EventType. This did not work.
Is this how it is intended to work?
A related question. At one point I download all GenericTypes in the
datastore (I use Objectify) and I want to see which of the lowest 8 types a
particular entity is. I am currently comparing the String of the class I
am looking for with substring of the class name of the GenericType. When I
do getClass().getName() on the GenericType, returned from the datastore, I
get something like:
com.packagename.shared.proxy.LevelThreeTypeProxyAutoBean_com_google_web_bindery_requestfactory_shared_impl_EntityProxyCategory_com_google_web_bindery_requestfactory_shared_impl_ValueProxyCategory_com_google_web_bindery_requestfactory_shared_impl_BaseProxyCategory$1
If I am trying to see if this is a
'com.packagename.shared.proxy.LevelThreeTypeProxy',
i compare that string to the left substring with length of whatever the
fully qualified name I'm looking for is.
Is there a better way to do this?
Thanks,
Jonathan
