58 Clase que modela la conexion con el RDBMS Oracle (tm).
60 Esta clase no puede usarse directamente, ya que la capa ANNA.dbms obliga a que todas las peticiones
61 se hagan atraves de una instancia anna::dbms::Connection.
63 Para obtener una conexion a una determinada base de datos habra que instanciar dicha base de datos
64 e invocar al metodo createConnection. Independientemente del tipo de conexion particular que la
65 base de datos retorne, debemos asignarlo a un puntero de tipo anna::dbms::Connection.
67 class Connection : public dbms::Connection {
70 Devuelve una cadena con la informacion referente a esta instancia.
71 @return Una cadena con la informacion referente a esta instancia.
73 std::string asString() const throw();
76 Operador de conversion.
77 \return El puntero al contexto asociado a este conexion.
79 operator OCISvcCtx*() throw() { return a_context; }
82 Database& a_oracleDatabase;
84 OCISession* a_session;
87 Connection(Database& database, const std::string& name, const char* user, const char* password);
88 bool isAvailable() const throw(RuntimeException) { return a_context != NULL && a_session != NULL && a_server != NULL; }
