Methods

addEvent(DataManagerEvent event) → void
Add event to the events stream.
close() Future<void>
Flush any buffered data and close this data manager. After calling close the data manager can no longer be used.
override
initialize(DataEndPoint dataEndPoint, SmartphoneDeployment deployment, Stream<Measurement> measurements) Future<void>
Initialize the data manager by specifying the study deployment, the dataEndPoint, and the stream of measurements events to handle.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onDone() Future<void>
When the data stream closes, the onDone handler is called. Default implementation is a no-op function. If another behavior is wanted, implementations of this abstract data manager should handle closing of the data stream.
override
onError(Object? error) Future<void>
When an error event is send on the stream, the onError handler is called.
override
onMeasurement(Measurement measurement) Future<void>
On each measurement collected, the onMeasurement handler is called.
inherited
toString() String
A string representation of this object.
