Detailed Description
template<class T>
class RTT::detail::CorbaTemplateProtocol< T >
For each transportable type T, specify the conversion functions.
- Warning:
- * * * B I G N O T E * * * * This class uses the TypeTransport of Orocos which uses (void*) for passing on data. TAO's CORBA implementation uses virtual inheritance, which does not work well together with (void*). That is, you must cast back to the exect same type the (void*) originated from and NOT to a sub- or super-class. That would have been allowed without virtual inheritance.
Hence, this class uses always the same base class (Expression_ptr) to communicate with the TypeTransport interface. Such that we know that when we receive a (void*) it came from an (Expression_ptr) and vice versa.
Don't obey this and you'll get immediate hard to dissect crashes ! * * * B I G N O T E * * * *
