JobWorkerImpl (Zeebe Client Java 1.2.3 API)

java.lang.Object
- io.camunda.zeebe.client.impl.worker.JobWorkerImpl

All Implemented Interfaces:

JobWorker, Closeable, AutoCloseable
```
public final class JobWorkerImpl
extends Object
implements JobWorker, Closeable
```
The job worker wants to have enough jobs to work on. Most of this class' implementation deals with the scheduling of polling for new jobs.
In order to get an initial set of jobs to work on, the job worker will schedule a first poll on construction. If a poll does not provide any new jobs, another poll is scheduled with a delay using the pollInterval.
If a poll successfully provides jobs, the worker submits each job to the job handler. Every time a job is completed, the worker checks if it still has enough jobs to work on. If not, it will poll for new jobs. To determine what is considered enough jobs it compares its number of remainingJobs with the activationThreshold.
If a poll fails with an error response, a retry is scheduled with a delay using the retryDelaySupplier to ask for a new pollInterval. By default this retry delay supplier is the ExponentialBackoff. This default is also used as a fallback for the user provided backoff. On the next success, the pollInterval is reset to its original value.
