Subject Re: avrogencpp generates vector of $Undefined$ type
Date Sun, 26 Aug 2012 12:26:04 GMT
I'm not an expert on the Avro C++ implementation, but I wonder if this
is cause of the nulls not being checked for in
http://svn.apache.org/repos/asf/avro/trunk/lang/c++/impl/avrogencpp.cc's
CodeGen::cppTypeOf method.
