类 FiniteTestSource<T>

java.lang.Object

org.apache.flink.streaming.util.FiniteTestSource<T>

所有已实现的接口:

Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.streaming.api.functions.source.SourceFunction<T>

public class FiniteTestSource<T>
extends Object
implements org.apache.flink.streaming.api.functions.source.SourceFunction<T>, org.apache.flink.api.common.state.CheckpointListener

A stream source that: 1) emits a list of elements without allowing checkpoints, 2) then waits for two more checkpoints to complete, 3) then re-emits the same elements before 4) waiting for another two checkpoints and 5) exiting.

This class was written to test the Bulk Writers used by the StreamingFileSink.
