[Boost-users] Serialising templates with smart pointers....

Subject: [Boost-users] Serialising templates with smart pointers....

I have the following:

_*1. An interface:*_

class IDeviceClientRequest
{
public:
    /** Empty virtual destructor. */
    virtual ~IDeviceClientRequest() {}

    /** Virtual methods to invoke on the smart pointer. */
    virtual EClientMessageIdentifier getMessageId() = 0;
}; // IDeviceClientRequest

_*2. A template class:*_

template<class Request>
class CDeviceClientRequest : public IDeviceClientRequest
{
public:
    // ...
    I have excluded the majority of the code for conciseness
    // ...

private:
    /**
     * Serialize or de-serialize the object.
     *
     * @param archive
     *           When the class Archive corresponds to an output 
archive, the
     *           & operator is defined similar to <<. Likewise, when the 
class Archive
     *           is a type of input archive the & operator is defined 
similar to >>.
     * @param version
     *           Version identifier for backwards compatibility between 
objects.
     */
    friend class boost::serialization::access;
    template<class Archive>
    void serialize(Archive            &archive,
                   const unsigned int  version)
    {
       archive & m_iMessageId
               & m_oData;
    }
}; // CDeviceClientRequest

_*3. A method to serialize from a file:*_

// Server receieves a request.
void devices::comms::CDeviceCommunication::receiveRequest(
std::unique_ptr<devices::request::IDeviceClientRequest>& request)
{
    // Open the file for read.
    std::ifstream file(getFilename().c_str());

    // Use boost to serialize the object from the file.
    boost::archive::binary_iarchive archive(file);
    archive >> *request;

    // Close the file.
    file.close();
}

What do I need to add to the interface class to stop the following 
compile error:

error C2039: 'serialize' : is not a member of 
'devices::request::IDeviceClientRequest'

Thanks,
