for consistency best to put as below as last statement in public section

[riju_, 2016/05/25 15:07:18]

Done.

+
+    DOMHighResTimeStamp timeStamp(bool& isNull);
+
+    void setTimeStamp(DOMHighResTimeStamp time) { m_timeStamp = time; }
+
+    SensorReading();

private or protected? since we have create methods..

[riju_, 2016/05/25 15:07:18]

Done.

+    SensorReading(bool providesTimeStamp, DOMHighResTimeStamp timestamp);
+
+protected:
+    bool m_canProvideTimeStamp;
+    DOMHighResTimeStamp m_timeStamp;
+};
