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
