org.apache.flink.api.java.operators.FilterOperator<T>

Type Parameters:

T - The type of the data set filtered by the operator.

All Implemented Interfaces:

UdfOperator<FilterOperator<T>>

@Deprecated
@Public
public class FilterOperator<T>
extends SingleInputUdfOperator<T,T,FilterOperator<T>>

Deprecated.

All Flink DataSet APIs are deprecated since Flink 1.18 and will be removed in a future Flink major version. You can still build your application in DataSet, but you should move to either the DataStream and/or Table API.

This operator represents the application of a "filter" function on a data set, and the result data set produced by the function.
