Executor<TConfig> class
abstract
A Executor is responsible for executing data collection based on a
configuration TConfig.
The behavior of an executor is controlled by its life-cycle methods: initialize, resume, pause, and stop. A restart can be used to restart an executor (e.g., if its configuration has changed).
The state property reveals the probe's current runtime state. The stateEvents is a stream of state changes which can be listen to as a broadcast stream.
If an error occurs the state of a probe becomes undefined. This is, for example,
used when an exception occur.
The executor returns collected data in the data stream. This is the main usage of an executor. For example, to listens to events and print them;
executor.data.forEach(print);

Methods
-
initialize(
TConfig configuration, [SmartphoneDeployment? deployment]) → void - Configure and initialize the executor before resuming it.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
pause(
) → void - Pause the executor. Paused until resume or stop is called.
-
restart(
) → void - Restart the executor.
-
resume(
) → void - Resume the executor.
-
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.
-
toString(
) → String -
A string representation of this object.
