Package org.apache.flink.streaming.api.functions.sink.legacy

Class PrintSinkFunction<IN>

java.lang.Object

org.apache.flink.api.common.functions.AbstractRichFunction

org.apache.flink.streaming.api.functions.sink.legacy.RichSinkFunction<IN>

org.apache.flink.streaming.api.functions.sink.legacy.PrintSinkFunction<IN>

Type Parameters:

IN - Input record type

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.RichFunction, org.apache.flink.api.common.SupportsConcurrentExecutionAttempts, SinkFunction<IN>

@Internal
public class PrintSinkFunction<IN>
extends RichSinkFunction<IN>
implements org.apache.flink.api.common.SupportsConcurrentExecutionAttempts

Deprecated.

This interface will be removed in future versions. Use the new PrintSink interface instead.

Implementation of the SinkFunction writing every tuple to the standard output or standard error stream.

Four possible format options: sinkIdentifier:taskId> output <- sinkIdentifier provided, parallelism > 1 sinkIdentifier> output <- sinkIdentifier provided, parallelism == 1 taskId> output <- no sinkIdentifier provided, parallelism > 1 output <- no sinkIdentifier provided, parallelism == 1
