类 TableOperatorWrapper<OP extends org.apache.flink.streaming.api.operators.StreamOperator<org.apache.flink.table.data.RowData>>

java.lang.Object

org.apache.flink.table.runtime.operators.multipleinput.TableOperatorWrapper<OP>

所有已实现的接口:

Serializable

public class TableOperatorWrapper<OP extends org.apache.flink.streaming.api.operators.StreamOperator<org.apache.flink.table.data.RowData>>
extends Object
implements Serializable

This class handles the close, endInput and other related logic of a StreamOperator. It also automatically propagates the end-input operation to the next wrapper that the outputEdges points to, so we only need to call the head wrapper's endOperatorInput(int) method.
