Package org.apache.flink.runtime.state.v2

Class AbstractValueState<K,N,V>

java.lang.Object

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

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

Type Parameters:

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

V - The type of values kept internally in state.

All Implemented Interfaces:

org.apache.flink.api.common.state.v2.State, org.apache.flink.api.common.state.v2.ValueState<V>, InternalKeyedState<K,N,V>, InternalPartitionedState<N>, InternalValueState<K,N,V>

public class AbstractValueState<K,N,V>
extends AbstractKeyedState<K,N,V>
implements InternalValueState<K,N,V>

A default implementation of ValueState which delegates all async requests to AsyncExecutionController.
