BluetoothProbe class

The BluetoothProbe scans for nearby and visible Bluetooth devices and collects a BluetoothDatum that lists each device found during the scan. Uses a PeriodicSamplingConfiguration for configuration the interval and duration of the scan.

Properties

bufferingStream → Stream

The stream of events to be buffered. Must be specified by sub-classes.

no setter, override

configuration → Measure?

The configuration of this executor as set when initialized.

no setter, inherited

controller ↔ StreamController<Datum>

A stream controller to add Datums to.

getter/setter pair, inherited

data → Stream<DataPoint>

The stream of DataPoint generated from this executor.

no setter, inherited

deployment → SmartphoneDeployment?

The deployment that this executor is part of executing.

no setter, inherited

deviceManager ↔ DeviceManager<DeviceRegistration, DeviceDescriptor>

The device that this probes uses to collect data.

getter/setter pair, inherited

enabled ↔ bool

Is this probe enabled, i.e. available for collection of data using the resume method.

getter/setter pair, inherited

hashCode → int

The hash code for this object.

no setter, inherited

measure → Measure?

The Measure that configures this probe.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

samplingConfiguration → PeriodicSamplingConfiguration?

The sampling configuration for this probe.

no setter, inherited

state → ExecutorState

The runtime state of this executor.

no setter, inherited

stateEvents → Stream<ExecutorState>

The runtime state changes of this executor.

no setter, inherited

stream → Stream<Datum>

The stream of Datum objects for this StreamProbe. Must be implemented by sub-classes.

no setter, inherited

subscription ↔ StreamSubscription?

getter/setter pair, inherited

timer ↔ Timer?

getter/setter pair, inherited

type → String?

The data type this probe is collecting.

no setter, inherited

Methods

addData(Datum datum) → void

Add a data point to the data stream.

inherited

addError(Object error) → void

Add an error to the data stream.

inherited

error() → void

inherited

getDatum() → Future<Datum?>

Subclasses should implement / override this method to collect the Datum. This method will be called every time data has been buffered for a duration and should return the final Datum for the buffered data.

override

initialize(Measure configuration, [SmartphoneDeployment? deployment]) → void

Configure and initialize the executor before resuming it.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onData(Datum datum) → void

inherited

onDone() → void

inherited

onError(Object error) → void

inherited

onInitialize() → bool

Callback when this executor is initialized. Returns true if succesfully initialized, false othervise.

inherited

onPause() → Future<bool>

Callback when this executor is paused. Returns true if successfully paused, false otherwise.

inherited

onRestart() → Future<bool>

Callback when this executor is restarted. Returns true if successfully restarted, false otherwise.

inherited

onResume() → Future<bool>

Callback when this executor is resumed. Returns true if successfully resumed, false otherwise.

inherited

onSamplingData(dynamic event) → void

Handler for handling onData events from the buffering stream.

override

onSamplingEnd() → void

Handler called when sampling period ends.

override

onSamplingStart() → void

Handler called when sampling period starts.

override

onStop() → Future<bool>

Callback when this executor is stopped. Returns true if successfully stopped, false otherwise.

inherited

pause() → void

Pause the executor. Paused until resume or stop is called.

inherited

restart() → void

Restart the executor.

inherited

resume() → void

Resume the executor.

inherited

stop() → void

Stop the executor. Once an executor is stopped, it cannot be resumed again. If you need to restart an executor, use the restart or pause and resume methods.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Constants

DEFAULT_TIMEOUT → const int

Default timeout for bluetooth scan - 4 secs
