org.apache.flink.cep.operator.CepOperator<IN,KEY,OUT>

类型参数:

IN - Type of the input elements

KEY - Type of the key on which the input stream is keyed

OUT - Type of the output elements

所有已实现的接口:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.streaming.api.operators.Input<IN>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.OneInputStreamOperator<IN,OUT>, org.apache.flink.streaming.api.operators.OutputTypeConfigurable<OUT>, org.apache.flink.streaming.api.operators.SetupableStreamOperator<OUT>, org.apache.flink.streaming.api.operators.StreamOperator<OUT>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator, org.apache.flink.streaming.api.operators.Triggerable<KEY,org.apache.flink.runtime.state.VoidNamespace>

public class CepOperator<IN,KEY,OUT>
extends org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator<OUT,PatternProcessFunction<IN,OUT>>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<IN,OUT>, org.apache.flink.streaming.api.operators.Triggerable<KEY,org.apache.flink.runtime.state.VoidNamespace>

CEP pattern operator for a keyed input stream. For each key, the operator creates a NFA and a priority queue to buffer out of order elements. Both data structures are stored using the managed keyed state.
