Interface InternalAggregatingState<K,N,IN,ACC,OUT>

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.
