Class FiniteTestSource<T>

java.lang.Object

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

All Implemented Interfaces:

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

Deprecated.

This class is based on the SourceFunction API, which is due to be removed. Use the new Source API instead.

@Deprecated
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.
