Method Detail

sensorReaderDidChangeAuthorizationStatus

default void sensorReaderDidChangeAuthorizationStatus(SRSensorReader reader,
                                                      long authorizationStatus)

Invoked when authorization status has changed

sensorReaderDidCompleteFetch

default void sensorReaderDidCompleteFetch(SRSensorReader reader,
                                          SRFetchRequest fetchRequest)

Invoked when a fetch has been completed successfully

sensorReaderDidFetchDevices

default void sensorReaderDidFetchDevices(SRSensorReader reader,
                                         NSArray<? extends SRDevice> devices)

sensorReaderFetchDevicesDidFailWithError

default void sensorReaderFetchDevicesDidFailWithError(SRSensorReader reader,
                                                      NSError error)

sensorReaderFetchingRequestDidFetchResult
```
default boolean sensorReaderFetchingRequestDidFetchResult(SRSensorReader reader,
                                                          SRFetchRequest fetchRequest,
                                                          SRFetchResult<?> result)
```
Invoked when a sample has been fetched
[@description] This callback can be called multiple times when there are multiple results.
[@note] The fetchResult is not valid after the callback is complete. If the caller needs to access the result at a later time, it must be copied not merely retained

Parameters:

fetchRequest - The request corresponding to the this result

result - One result of the fetch. The caller is expected to know what type of sample is returned.

Returns:

The delegate should return YES if the fetch should continue, NO if the fetch should stop

sensorReaderFetchingRequestFailedWithError

default void sensorReaderFetchingRequestFailedWithError(SRSensorReader reader,
                                                        SRFetchRequest fetchRequest,
                                                        NSError error)

Invoked when a fetch has completed with an error

sensorReaderStartRecordingFailedWithError

default void sensorReaderStartRecordingFailedWithError(SRSensorReader reader,
                                                       NSError error)

Invoked if there was an error starting recording for a given sensor

sensorReaderStopRecordingFailedWithError

default void sensorReaderStopRecordingFailedWithError(SRSensorReader reader,
                                                      NSError error)
