Methods

Modifier and Type	Method and Description
byte[]	Acquire(String sensor, String query) Method to acquire sensor data For each sensor, we will fire a handler event to start the sensor reading, wait for the semaphore, then read the latest sensor value and fire another event to unregister the sensor callback -> this saves processing!
void	destroyHandler() Method to release all handler resources Here, we unregister the sensor listener, if registered, and release all semaphores
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 sensors can be used and depending on which sensors are available on the device
void	History(String sensor) Method to view historical chart of the given sensor symbol
String	Share(String sensor) Method to share the last value of the given sensor
