Detailed Description
Derived class intended for rolling_window specific aggregation usage.
As an example, rolling_window will only accept rolling_aggregation inputs, and the appropriate derived classes (sum_aggregation, mean_aggregation, etc) derive from this interface to represent these valid options.
