void |
open()
已过时。
This method is called immediately before any elements are processed, it should contain the
operator's initialization logic, e.g. state initialization.
|
void |
processElement(StreamRecord<IN> element)
已过时。
Processes one element that arrived at this operator.
|
void |
setOutputType(org.apache.flink.api.common.typeinfo.TypeInformation<OUT> outTypeInfo,
org.apache.flink.api.common.ExecutionConfig executionConfig)
已过时。
Is called by the
org.apache.flink.streaming.api.graph.StreamGraph#addOperator(Integer, String, StreamOperator, TypeInformation, TypeInformation, String)
method when the StreamGraph is generated. |
