类 UnionTransformation<T>

java.lang.Object

org.apache.flink.api.dag.Transformation<T>

org.apache.flink.streaming.api.transformations.UnionTransformation<T>

类型参数:

T - The type of the elements that result from this UnionTransformation

@Internal
public class UnionTransformation<T>
extends org.apache.flink.api.dag.Transformation<T>

This transformation represents a union of several input Transformations.

This does not create a physical operation, it only affects how upstream operations are connected to downstream operations.
