public class ResultSetProcessorRowPerEventImpl extends Object
Result set processor for the case: aggregation functions used in the select clause, and no group-by, and not all of the properties in the select clause are under an aggregation function.

This processor does not perform grouping, every event entering and leaving is in the same group. The processor generates one row for each event entering (new event) and one row for each event leaving (old event). Aggregation state is simply one row holding all the state.
