Class SensorDeviceAvailabilityTester

java.lang.Object
  de.unikassel.android.sdcframework.devices.SensorDeviceAvailabilityTester

public final class SensorDeviceAvailabilityTester
extends Object

The global singleton to test for sensor device availability. With the first call to the {link configure(Set, Context) method, the availability of supported devices is tested and the identifiers will be stored to be queried later by a call to getAvailableSensorDevices().

Field Summary

private boolean	initialized flag if sensor device list is initialized
private static SensorDeviceAvailabilityTester	instance The singleton instance of the sensor availability tester manager
private Vector<SensorDeviceIdentifier>	vecSensorDevices Vector to store the detected sensor devices

Constructor Summary

private

SensorDeviceAvailabilityTester() Constructor

Method Summary

void	configure(Set<SensorDeviceIdentifier> configuredDevices, Context applicationContext) Method to inject the sensor devices from service configuration
private void	detectAvailableSensorDevices(Set<SensorDeviceIdentifier> configuredDevices, Context applicationContext) Does detect available sensor devices
List<SensorDeviceIdentifier>	getAvailableSensorDevices() Getter for available Sensor devices
static SensorDeviceAvailabilityTester	getInstance() Access to the singleton instance of the preference manager
private Vector<SensorDeviceIdentifier>	getVecSensorDevices() Getter for the vecSensorDevices
private boolean	isDeviceAvailable(SensorDeviceIdentifier identifier, Context applicationContext) Test method for availability of a specific sensor device
boolean	isInitialized() Getter for the initialized
private void	setInitialized(boolean initialized) Setter for the initialized
private void	setVecSensorDevices(Vector<SensorDeviceIdentifier> vecSensorDevices) Setter for the vecSensorDevices
