    Method overview

    void addListener(in nsIDeviceMotionListener aListener);

    void removeListener(in nsIDeviceMotionListener aListener);
    void removeWindowListener(in nsIDOMWindow aWindow); Native code only!

    Methods

    addListener()

    When called, the accelerometer support implementation must begin to notify the specified nsIDeviceMotionListener by calling its nsIDeviceMotionListener.onAccelerationChange() method as appropriate to share updated acceleration data.

    void addListener(
      in nsIDeviceMotionListener aListener
    );
    
    Parameters
    aListener
    The nsIDeviceMotionListener object whose nsIDeviceMotionListener.onAccelerationChange() method should be called with updated acceleration data.

    Native code only!

    addWindowListener

    Sets the nsIAccelerometer as the source for MozOrientation events on the specified DOM window.

    void addWindowListener(
      in nsIDOMWindow aWindow
    );
    
    Parameters
    aWindow
    The DOM window that the accelerometer should begin sending MozOrientation events to.

    removeListener()

    Tells the accelerometer to stop sending updates to the specified nsIDeviceMotionListener.

    void removeListener(
      in nsIDeviceMotionListener aListener
    );
    
    Parameters
    aListener
    The nsIDeviceMotionListener object to which no further updates should be sent.

    Native code only!

    removeWindowListener

    Removes the nsIAccelerometer as the source for MozOrientation events on the specified DOM window.

    void removeWindowListener(
      in nsIDOMWindow aWindow
    );
    
    Parameters
    aWindow
    The DOM window that the accelerometer should stop sending MozOrientation events to.
