CSensorDataCompensator Class Reference

class CSensorDataCompensator : public CBase

Class provides operations to compensate sensor data.

Usage:

 #include <sensordatacompensator.h>
 #include <sensrvaccelerometersensor.h>

 // Client creates the compensator instance as a member.
 // This compensates the axis data received from accelerometer.
 // The data is compensated according to both device and UI rotation.
 // See sensrvtypes.h and sensordatacompensationtypes.h for more information.
 iDataCompensator = CSensorDataCompensator::NewL(
                        KSensrvChannelTypeIdAccelerometerXYZAxisData,
                        ESensorCompensateDeviceAndUIOrientation );

 // Data compensation is done in client's MSensrvDataListener::DataReceived() implementation 
 // where 'iSensorChannel' contains the accelerometer channel instance.
 TPckgBuf<TSensrvAccelerometerAxisData> dataPckgBuf;
 // Get data from accelerometer ( iSensorChannel->GetData( dataPckgBuf ) )
 TInt err( iDataCompensator->Compensate( dataPckgBuf ) );

 // Client deletes the compensator instance in destructor.
 delete iDataCompensator;
