org.apache.flink.runtime.jobgraph.InputOutputFormatVertex

All Implemented Interfaces:

Serializable

public class InputOutputFormatVertex
extends JobVertex

A task vertex that runs an initialization and a finalization on the master. If necessary, it tries to deserialize input and output formats, and initialize and finalize them on master.
