I have a vector of boost::tuple objects that is a member variable in a class of mine. I want to be able to create an instance of my wrapper class and construct it off of a tuple_list_of(), and essentially forward those values to the container itself. I haven't seen a way to do this yet. An example is below. Note that my constructor in the class was my attempt to get this working, but instead it will not compile. For some reason boost.assign thinks that the EnumErrorInfo class is the container. template<class T> class EnumErrorInfo { public: typedef boost::tuple<T, char const*, char const*> Tuple; typedef std::vector<Tuple> TupleVector; EnumErrorInfo( TupleVector const& assignment ) : m_errorInfo( assignment ) {} Tuple const& getErrorInfo( T error_code ) { TupleVector::const_iterator it = std::find_if( m_errorInfo.begin(), m_errorInfo.end(), MatchErrorCodePred( error_code ) ); if( it != m_errorInfo.end() ) { return *it; } static Tuple const unknown_info( error_code, "????", "No error info available for this code" ); return unknown_info; } private: class MatchErrorCodePred { public: MatchErrorCodePred( T error_code ) : m_errorCode( error_code ) {} bool operator() ( Tuple const& t ) { return t.get<0>() == m_errorCode; } private: DomInterfaceErrors m_errorCode; }; TupleVector m_errorInfo; }; And here is how I'd like to initialize the class: EnumErrorInfo<DomInterfaceErrors> g_errorInfo = tuple_list_of ( GDE_OK, "GDE_OK", "DBL: Opeartion successfully completed" ) ( GDE_GDD_DIRUSERS, "GDE_GDD_DIRUSERS", "AQX: Unable to get directory users." ) ;
