      • getAggregated

        V getAggregated​(java.lang.Object key,
                java.lang.String function,
                int n)

        Gets the aggregate field value after applying a "window transformation" to the current position.

        Parameters:
        key - The field name.
        function - The aggregation function name. The implementation should recognize and support all Lag.Aggregate enum constant values (except for the `none` value).
        n - The window size.
        Returns:
        The aggregate field value.
