public interface IndexerBasedAggregatorRecipe
extends ReteNodeRecipe

A representation of the model object 'Indexer Based Aggregator Recipe'. Represents a (compound) node that performs an aggregation operation. Parent must be a ProjectionIndexer, which defines how tuples are to be aggregated. Usable only through an Join with an AggregatorIndexer as the right parent

The following features are supported:

• Parent
