org.apache.flink.runtime.state.internal

Interface InternalReducingState<K,N,T>

Type Parameters:

K - The type of key the state is associated to

N - The type of the namespace

T - The type of elements in the aggregated by the ReduceFunction

All Superinterfaces:

org.apache.flink.api.common.state.AppendingState<T,T>, InternalAppendingState<K,N,T,T,T>, InternalKvState<K,N,T>, InternalMergingState<K,N,T,T,T>, org.apache.flink.api.common.state.MergingState<T,T>, org.apache.flink.api.common.state.ReducingState<T>, org.apache.flink.api.common.state.State

public interface InternalReducingState<K,N,T>
extends InternalMergingState<K,N,T,T,T>, org.apache.flink.api.common.state.ReducingState<T>

The peer to the ReducingState in the internal state type hierarchy.

See InternalKvState for a description of the internal state hierarchy.
