- 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.ACC - The type of the accumulator (intermediate aggregation state).OUT - The type of the values that are returned from the state.
- All Superinterfaces:
AggregatingState<IN,OUT>, AppendingState<IN,OUT,OUT>, InternalAppendingState<K,N,IN,ACC,OUT,OUT>, InternalKeyedState<K,N,ACC>, InternalMergingState<K,N,IN,ACC,OUT,OUT>, InternalPartitionedState<N>, MergingState<IN,OUT,OUT>, State
- All Known Subinterfaces:
InternalReducingState<K,N,T>
- All Known Implementing Classes:
AbstractAggregatingState, AbstractReducingState, AggregatingStateAdaptor, ForStAggregatingState, ForStReducingState, ReducingStateAdaptor
public interface InternalAggregatingState<K,N,IN,ACC,OUT>
extends InternalMergingState<K,N,IN,ACC,OUT,OUT>, AggregatingState<IN,OUT>, InternalKeyedState<K,N,ACC>
This class defines the internal interface for aggregating state.
