IAggregator Interface

Base interface for fact aggregators. An aggregator is a stateful element of the rules engine, that receives matching facts of a particular kind, and can combine them into a synthetic fact, that is then used by the downstream logic in the rule. Aggregator also receives updates and removals for the matching facts, so that it can keep the corresponding aggregate facts in sync. An aggregator must be supplemented by a corresponding implementation of IAggregatorFactory that knows how to create new instances of the aggregator.
