No exception is thrown

Deserialize from QByteArray

                                             {
        auto _id = _t->getTypeId();

        /// No exception is thrown
        if (memory_.count(_id) == 0) return;

        /// Deserialize from QByteArray
        QDataStream _s(memory_.at(_id));
        _t->fromStream(_s);
      }

template<typename INTERFACE>

void omni::TypeIdMemory< INTERFACE >::store ( interface_type const *  _t )

inline

Store object with interface in memory.

Serialize to QByteArray

                                           {
        auto _id = _t->getTypeId();

        QBuffer _buf;
        /// Serialize to QByteArray
        _buf.open(QIODevice::WriteOnly);
        QDataStream _s(&_buf);
        _t->toStream(_s);
        memory_[_id] = _buf.data();
      }
