All Implemented Interfaces:

PeriodicScannable, Spotter

public class BluetoothSpotter

extends AsyncSpotter

implements PeriodicScannable

Spotter for Bluetooth on systems with JSR-82 support.

Constructor Summary

BluetoothSpotter()

BluetoothSpotter(long intervalMillis, boolean filterPhones)

Method Summary

protected void	cancelScan() Stops the scan that was started in startOneScan(EventSystem)
void	close() Unloads resources used by the spotter.
protected Measurement	getMeasurementImpl() Collect Measurements with a blocking implementation and return them.
long	getPeriodicScanInterval()
protected long	nextScanInterval()
void	open() Load resources used by the spotter.
void	setPeriodicScanInterval(long intervalMillis) Sets the minimum amount of time between SpotterListener.gotMeasurement(Spotter, Measurement) callbacks to listeners.
protected void	startOneScan(EventSystem evs) This performs a single scan of the environment that should call AbstractSpotter.notifyGotMeasurement(EventSystem, Measurement) upon collecting the Measurement.

public BluetoothSpotter(long intervalMillis,
                        boolean filterPhones)

Method Detail

setPeriodicScanInterval

public void setPeriodicScanInterval(long intervalMillis)

Description copied from interface: PeriodicScannable

Sets the minimum amount of time between SpotterListener.gotMeasurement(Spotter, Measurement) callbacks to listeners.

Specified by:

setPeriodicScanInterval in interface PeriodicScannable

getPeriodicScanInterval

public long getPeriodicScanInterval()

Specified by:

getPeriodicScanInterval in interface PeriodicScannable

open

public void open()
          throws SpotterException

Description copied from interface: Spotter

Load resources used by the spotter. Applications should be able to invoke this methods multiple times in sequence and have the "right" things happen. All Spotters should be opened before being used.

Specified by:

open in interface Spotter

Throws:

SpotterException - if the necessary hardware or software for this spotter is not present

close

public void close()

Description copied from interface: Spotter

Unloads resources used by the spotter. Multiple calls to close are ok.

Specified by:

close in interface Spotter

nextScanInterval

protected long nextScanInterval()

Specified by:

nextScanInterval in class AsyncSpotter

Returns:

the interval that the spotter should wait before invoking the next scan

startOneScan

protected void startOneScan(EventSystem evs)

Description copied from class: AsyncSpotter

This performs a single scan of the environment that should call AbstractSpotter.notifyGotMeasurement(EventSystem, Measurement) upon collecting the Measurement.

Specified by:

startOneScan in class AsyncSpotter

Parameters:

evs - the EventSystem to pass through to notifyGotMeasurement

cancelScan

protected void cancelScan()

Description copied from class: AsyncSpotter

Stops the scan that was started in AsyncSpotter.startOneScan(EventSystem)

Specified by:

cancelScan in class AsyncSpotter

getMeasurementImpl

protected Measurement getMeasurementImpl()
                                  throws SpotterException

Description copied from class: AsyncSpotter

Collect Measurements with a blocking implementation and return them.

Specified by:

getMeasurementImpl in class AsyncSpotter

Throws:

SpotterException
