BufferingPeriodicProbe class abstract

An type of probe which collects data for a period of time and then return a measurement from this collected data.

Probes of this type uses a PeriodicSamplingConfiguration that specify the interval of starting sampling, and the duration of the sampling window. Once this sampling window is over, the final measurement is collected from the getMeasurement method and send to the main measurements stream.

When sampling starts, the onSamplingStart handle is called. When the sampling window ends, the onSamplingEnd handle is called.

Methods

addError(Object error, [StackTrace? stacktrace]) → void
Add error to the measurements stream.
inherited
addMeasurement(Measurement measurement) → void
Add measurement to the measurements stream.
inherited
arePermissionsGranted() → Future<bool>
Does this probe has the permissions needed to run?
inherited
dispose() → void
Dispose of this executor.
inherited
error() → void
inherited
getMeasurement() → Future<Measurement?>
Subclasses should implement / override this method to collect the Measurement. This method will be called every time data has been buffered for a duration and should return the final Measurement for the buffered data.
override
initialize(Measure configuration, [SmartphoneDeployment? deployment]) → void
Configure and initialize the executor before starting it.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onDispose() → Future<void>
Callback when this executor is disposed.
inherited
onInitialize() → bool
Callback when this executor is initialized. Returns true if successfully initialized, false otherwise.
inherited
onRestart() → Future<bool>
Callback when this executor is to be restarted. Returns true if the executor is ready to restart (default), false otherwise.
inherited
onSamplingEnd() → void
Handler called when sampling period ends.
onSamplingStart() → void
Handler called when sampling period starts.
onStart() → Future<bool>
Callback when this executor is started. Returns true if successfully started, false otherwise.
override
onStop() → Future<bool>
Callback when this executor is stopped. Returns true if successfully stopped, false otherwise.
override
requestPermissions() → Future<bool>
Request the permissions needed for this probe to run. Return true if all permissions are granted. Only used on Android - iOS automatically request permissions when a resource (like the microphone) is accessed.
inherited
restart() → void
Restart the executor.
inherited
start() → void
Start the executor.
inherited
stop() → void
Stop the executor. Stopped until start or restart is called.
inherited
toString() → String
A string representation of this object.
