getSourceContext

public static <OUT> SourceFunction.SourceContext<OUT> getSourceContext(TimeCharacteristic timeCharacteristic,
                                                                       ProcessingTimeService processingTimeService,
                                                                       Object checkpointLock,
                                                                       Output<StreamRecord<OUT>> output,
                                                                       long watermarkInterval,
                                                                       long idleTimeout,
                                                                       boolean emitProgressiveWatermarks)

Depending on the TimeCharacteristic, this method will return the adequate SourceFunction.SourceContext. That is:

• TimeCharacteristic.IngestionTime = AutomaticWatermarkContext
• TimeCharacteristic.ProcessingTime = NonTimestampContext
• TimeCharacteristic.EventTime = ManualWatermarkContext
