Class ScannerStateAwareSensorDevice

java.lang.Object
  de.unikassel.android.sdcframework.devices.AbstractSensorDevice
      de.unikassel.android.sdcframework.devices.ScannerStateAwareSensorDevice

All Implemented Interfaces:

SensorDevice, VisitableDevice

Direct Known Subclasses:

AbstractAndroidSensorDevice, AbstractLocationDevice, GSMDevice

public abstract class ScannerStateAwareSensorDevice
extends AbstractSensorDevice

This class is an extension of the abstract sensor device for such devices, which have to be aware of the scanner running state. In most cases these are devices implementing the SampleProvidingSensorDevice interface.

Constructor

Parameters:

deviceId - the device identifier

Method Detail

onConfigurationChanged

protected void onConfigurationChanged()

Description copied from class: AbstractSensorDevice

Callback to signal configuration of device has changed

Specified by:

onConfigurationChanged in class AbstractSensorDevice

enableDeviceScanning

public final boolean enableDeviceScanning(boolean enabled,
                                          Context context)

Description copied from interface: SensorDevice

Setter for device scanning enabled state

Specified by:

enableDeviceScanning in interface SensorDevice

Overrides:

enableDeviceScanning in class AbstractSensorDevice

Parameters:

enabled - true to enable device scanning, false to disable it

context - the application context

Returns:

true if successful enabled, false otherwise

onScannerRunningStateChange

protected abstract void onScannerRunningStateChange(boolean isRunning,
                                                    Context context)

Handler to react on scanner state changes. It is called after each state change and signals the new running state

Parameters:

isRunning - the current scanner state after state change

context - the context
