java.lang.Object

org.apache.flink.runtime.state.v2.InternalKeyedState<K,V>

org.apache.flink.runtime.state.v2.InternalMapState<K,UK,V>

Type Parameters:

K - The type of partitioned key the state is associated to.

UK - The type of user key of this state.

V - The type of values kept internally in state.

All Implemented Interfaces:

org.apache.flink.api.common.state.v2.MapState<UK,V>, org.apache.flink.api.common.state.v2.State

public class InternalMapState<K,UK,V>
extends InternalKeyedState<K,V>
implements org.apache.flink.api.common.state.v2.MapState<UK,V>
