Method Detail

getAccSource

public final AbstractAccelerometerDataSource getAccSource()

Description copied from interface: ObservableSensorScanner

Getter for the acceleration sample source.

Returns:

the acceleration sample source

onActivationStateChange

protected final void onActivationStateChange(boolean active)

Handler for activation state changes

Overrides:

onActivationStateChange in class AbstractObservableSensorScanner<AccSensorObservationDimensions,Double>

Parameters:

active - the new activation state

getNewSensorObservation

protected SensorObservation<AccSensorObservationDimensions,Double> getNewSensorObservation(Long ts)

Description copied from class: AbstractObservableSensorScanner

Does take samples from sources and creates a new sensor observation.

Specified by:

getNewSensorObservation in class AbstractObservableSensorScanner<AccSensorObservationDimensions,Double>

Parameters:

ts - the time stamp for the observation

Returns:

a new sensor observation, or null in case of an error

delegateNotify

public void delegateNotify(SampleGapErrorEvent data)

Description copied from interface: SensorScanner

Does delegate the notification about external recognition of sample gap error events to the accelerometer source.

Parameters:

data - the sample gap error event notifications to delegate
