Class HeartMonitorHandler

java.lang.Object

com.airs.handlers.HeartMonitorHandler

All Implemented Interfaces:

Constructor and Description
HeartMonitorHandler(Context airs) Constructor, allocating all necessary resources for the handler Here, it's arming the semaphore

Method Summary

Methods

Modifier and Type	Method and Description
byte[]	Acquire(String sensor, String query) Method to acquire sensor data Here, we first try to connect to the Zephyr for an initial connection (but only once!) then, it's a simple wait for the semaphores to be released
void	destroyHandler() Method to release all handler resources Here, we release all handler semaphores as well as close the BT socket, closing also the BT read thread
void	Discover() Method to discover the sensor symbols support by this handler As the result of the discovery, appropriate Sensor entries will be added to the SensorRepository, if the monitor is selected by the user to be used This does not mean that the sensor has been found via BT!
void	History(String sensor) Method to view historical chart of the given sensor symbol - supporting timeline for heart rate and instant speed
void	run() This thread keeps on reading the BT serial port
String	Share(String sensor) Method to share the last value of the given sensor

Constructor Detail

HeartMonitorHandler

public HeartMonitorHandler(Context airs)

Constructor, allocating all necessary resources for the handler Here, it's arming the semaphore

Parameters:

airs - Reference to the calling Context

Method Detail

destroyHandler

public void destroyHandler()

Method to release all handler resources Here, we release all handler semaphores as well as close the BT socket, closing also the BT read thread

Specified by:

destroyHandler in interface Handler

Handler.destroyHandler()

Acquire

public byte[] Acquire(String sensor,
             String query)

Method to acquire sensor data Here, we first try to connect to the Zephyr for an initial connection (but only once!) then, it's a simple wait for the semaphores to be released

Specified by:

Acquire in interface Handler

Parameters:

sensor - String of the sensor symbol

query - String of the query to be fulfilled - not used here

Share

public String Share(String sensor)

Method to share the last value of the given sensor

Specified by:

Share in interface Handler

Parameters:

sensor - String of the sensor symbol to be shared

Returns:

human-readable string of the last sensor value

See Also:

Handler.Share(java.lang.String)

History

public void History(String sensor)

Method to view historical chart of the given sensor symbol - supporting timeline for heart rate and instant speed

Specified by:

History in interface Handler

Parameters:

sensor - String of the symbol for which the history is being requested

See Also:

Handler.History(java.lang.String)

Discover

public void Discover()

Method to discover the sensor symbols support by this handler As the result of the discovery, appropriate Sensor entries will be added to the SensorRepository, if the monitor is selected by the user to be used This does not mean that the sensor has been found via BT!

Specified by:

Discover in interface Handler

run

public void run()

This thread keeps on reading the BT serial port

Specified by:

run in interface Runnable
