class telux::sensor::ISensorEventListener |
This file hosts the sensor interfaces to configure, activate or get data from the individual sensors available - Gyroscope, Accelerometer, etc.
ISensorEventListener interface is used to receive notifications related to sensor events and configuration updates
The listener method can be invoked from multiple different threads. Client needs to make sure that implementation is thread-safe.

This function is called to notify any change in sensor configuration.
[in] | configuration | - The new configuration for the sensor telux::sensor::SensorConfiguration. Fields that have changed can be identified using the telux::sensor::SensorConfiguration::updateMask and fields that are valid can be identified using telux::sensor::SensorConfiguration::validityMask |

Configure sensor with desired sampling rate and batch count. Any change in sampling rate or batch count of the sensor will be notified via telux::sensor::ISensorEventListener::onConfigurationUpdate.
In case a sensor needs to be reconfigured after having been activated, the sensor should be deactivated, configured and activated again as a part of the reconfiguration process.
It is always recommended that configuration of a sensor is done before activating it. If a sensor is activated without configuration, the sensor is configured with a default configuration and activated. The default configuration would have the sampling rate set to minimum sampling rate supported telux::sensor::SensorInfo::samplingRates and the batch count set to maximum batch count supported telux::sensor::SensorInfo::maxBatchCountSupported
[in] | configuration | - The desired configuration for the sensor telux::sensor::SensorConfiguration. Ensure the required validity mask telux::sensor::SensorConfiguration::validityMask is set for the configuration. |

pure virtual |
Get the current configuration of this sensor

Activate the sensor. Once activated, any available sensor event will be notified via telux::sensor::ISensorEventListener::onEvent

class telux::sensor::ISensorManager |
Sensor Manager class provides APIs to interact with the sensor sub-system and get access to other sensor objects which can be used to configure, activate or get data from the individual sensors available - Gyro, Accelero, etc.

pure virtual |
Get an instance of ISensor to interact with the underlying sensor. The provided instance is not a singleton. Everytime this method is called a new sensor object is created. It is the caller's responsibility to maintain the object Every instance of the sensor returned acts as new client and can configure the underlying sensor with it's own configuration and it's own callbacks for telux::sensor::ISensorEvent and configuration update among other events telux::sensor::ISenorEventListener.
[out] | sensor | - An instance of telux::sensor::ISensor to interact with the underlying sensor is provided as a result of the method If the initialization of the sensor and underlying system fails, sensor is set to nullptr |
[in] | name | - The unique name of the sensor telux::sensor::SensorInfo::name that was provided in the list of sensor information by telux::sensor::getAvailableSensorInfo |
