| Modifier and Type | Method and Description |
|---|---|
void |
onProcessingTime(long timestamp)
Deprecated.
This method is invoked with the timestamp for which the trigger was scheduled.
|
void |
open()
Deprecated.
This method is called immediately before any elements are processed, it should contain the
operator's initialization logic, e.g.
|
void |
processElement(StreamRecord<T> element)
Deprecated.
Processes one element that arrived at this operator.
|
void |
processWatermark(Watermark mark)
Deprecated.
Processes a
Watermark. |
