Re: [xmlvm-users] newbie questions about generated code

[Markus N. <mar...@gm...>]

Hi,

@1: This is to allow covariant return types (see
http://en.wikipedia.org/wiki/Covariant_return_type) which are supported by
Java but not in C#. Everything is simply returning Object and cast to the
appropriate type later.

@2: If it is indeed a bug (no time to look into this right now) and you've
a patch to fix it please submit it. Details of how to do this are described
here: http://xmlvm.org/contribute/

Cheers,
Markus
