Modifier and Type | Method and Description |
---|---|
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<IN> element)
Deprecated.
Processes one element that arrived at this operator.
|
void |
setOutputType(TypeInformation<OUT> outTypeInfo,
ExecutionConfig executionConfig)
Deprecated.
Is called by the
org.apache.flink.streaming.api.graph.StreamGraph#addOperator(Integer,
String, StreamOperator, TypeInformation, TypeInformation, String) method when the StreamGraph is generated. |
