Does not implement change flags, which means that if iValue is changed while the mapping function is in use, timed values will not notify the change. Usage:

        //Create constant mapping function instant
 CAlfConstantMappingFunction* imageXposMappingFun = CAlfConstantMappingFunction::NewL(*iEnv);  
 
 TAlfTimedPoint timedPoint;
 //Set mapping function on x timed value
 timedPoint.iX.SetValueNow(0); 
 timedPoint.iX.SetTarget( 2000 );
 timedPoint.iX.SetMappingFunctionIdentifier( imageXposMappingFun->MappingFunctionIdentifier() );
 
 //Set mapping function on Y timed value
 timedPoint.iY.SetValueNow(0); 
 timedPoint.iY.SetTarget(2000);
 timedPoint.iY.SetMappingFunctionIdentifier( imageYposMappingFunction->MappingFunctionIdentifier() );
 //Set position of image visual
 iImageVisual->SetPos( timedPoint );
