Interface ProcessingTimeServiceAware

All Known Implementing Classes:
AbstractStreamOperatorFactory, CollectSinkOperatorFactory, CommitterOperatorFactory, ContinuousFileReaderOperatorFactory, EvictingWindowOperatorFactory, SimpleInputFormatOperatorFactory, SimpleOperatorFactory, SimpleOutputFormatOperatorFactory, SimpleUdfStreamOperatorFactory, SinkWriterOperatorFactory, SourceOperatorFactory, TimestampsAndWatermarksOperatorFactory, WindowOperatorFactory
@PublicEvolving public interface ProcessingTimeServiceAware
Interface for StreamOperatorFactory, which enables stream operators to access ProcessingTimeService.

For an stream operator, if it needs to access the ProcessingTimeService, it must be created through a operator factory that implements ProcessingTimeServiceAware, and the operator factory should set the ProcessingTimeService instance into the stream operator.
