InternalAppendingState (Flink : 2.0-SNAPSHOT API)

Type Parameters:

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

N - The namespace type.

IN - The type of the values that are added into the state.

SV - The type of the intermediate state.

OUT - The type of the values that are returned from the state.

SYNCOUT - Type of the value that can be retrieved from the state by synchronous interface.

All Superinterfaces:

AppendingState<IN,OUT,SYNCOUT>, InternalKeyedState<K,N,SV>, InternalPartitionedState<N>, State

All Known Subinterfaces:

InternalAggregatingState<K,N,IN,ACC,OUT>, InternalMergingState<K,N,IN,SV,OUT,SYNCOUT>, InternalReducingState<K,N,T>

All Known Implementing Classes:

AbstractAggregatingState, AbstractReducingState, AggregatingStateAdaptor, ForStAggregatingState, ForStReducingState, MergingStateAdaptor, ReducingStateAdaptor
```
public interface InternalAppendingState<K,N,IN,SV,OUT,SYNCOUT>
extends InternalKeyedState<K,N,SV>, AppendingState<IN,OUT,SYNCOUT>
```
This class defines the internal interface for appending state.
