Comunica Record Intermediate Results Process Iterator Actor

A Comunica Record Intermediate Results Process Iterator Actor. This actor wraps (intermediate) iterators produced during query execution. This wrapper calls the updateStatistic function of @comunica/statistic-intermediate-results which should be present in the context. This statistic should be added to the context by the user. This is possible when using Comunica in a javascript application or by implementing your own actor-context-preprocess actor that adds this statistic to the context.

This module is part of the Comunica framework, and should only be used by developers that want to build their own query engine.
