WebLogAnalysis.AntiJoinVisits (Flink : Examples : Batch 1.19.3-cp4 API)

java.lang.Object
- org.apache.flink.examples.java.relational.WebLogAnalysis.AntiJoinVisits

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.functions.CoGroupFunction<org.apache.flink.api.java.tuple.Tuple3<Integer,String,Integer>,org.apache.flink.api.java.tuple.Tuple1<String>,org.apache.flink.api.java.tuple.Tuple3<Integer,String,Integer>>, org.apache.flink.api.common.functions.Function

Enclosing class:

WebLogAnalysis
```
public static class WebLogAnalysis.AntiJoinVisits
extends Object
implements org.apache.flink.api.common.functions.CoGroupFunction<org.apache.flink.api.java.tuple.Tuple3<Integer,String,Integer>,org.apache.flink.api.java.tuple.Tuple1<String>,org.apache.flink.api.java.tuple.Tuple3<Integer,String,Integer>>
```
CoGroupFunction that realizes an anti-join. If the first input does not provide any pairs, all pairs of the second input are emitted. Otherwise, no pair is emitted.
