AbstractStreamOperatorFactory (Flink : Runtime 2.1.0 API)

java.lang.Object
- org.apache.flink.streaming.api.operators.AbstractStreamOperatorFactory<OUT>

All Implemented Interfaces:

Serializable, StreamOperatorFactory<OUT>, ProcessingTimeServiceAware

Direct Known Subclasses:

CommitterOperatorFactory, ContinuousFileReaderOperatorFactory, SimpleOperatorFactory, SinkWriterOperatorFactory, SourceOperatorFactory, TimestampsAndWatermarksOperatorFactory, WindowOperatorFactory
```
@Experimental
public abstract class AbstractStreamOperatorFactory<OUT>
extends Object
implements StreamOperatorFactory<OUT>, ProcessingTimeServiceAware
```
Base class for all stream operator factories. It implements some common methods and the ProcessingTimeServiceAware interface which enables stream operators to access ProcessingTimeService.
