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

Class AbstractListState<K,N,V>

java.lang.Object

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

org.apache.flink.runtime.state.v2.AbstractListState<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.AppendingState<V,org.apache.flink.api.common.state.v2.StateIterator<V>,Iterable<V>>, org.apache.flink.api.common.state.v2.ListState<V>, org.apache.flink.api.common.state.v2.MergingState<V,org.apache.flink.api.common.state.v2.StateIterator<V>,Iterable<V>>, org.apache.flink.api.common.state.v2.State, InternalKeyedState<K,N,V>, InternalListState<K,N,V>, InternalPartitionedState<N>

public class AbstractListState<K,N,V>
extends AbstractKeyedState<K,N,V>
implements InternalListState<K,N,V>

A default implementation of ListState which delegates all async requests to StateRequestHandler.
