Oracle® Coherence .NET API Reference Release 3.7.1
E22844-03

Composite IValueExtractor implementation based on an array of extractors.

Namespace:  Tangosol.Util.Extractor
Assembly:  Coherence (in Coherence.dll) Version: 3.7.1.23 (3.7.1.23)

Syntax

C#
public class MultiExtractor : AbstractCompositeExtractor

Remarks

All extractors in the array are applied to the same target object and the result of the extraction is an IList of extracted values.

Common scenarios for using the MultiExtractor involve the DistinctValues or GroupAggregator aggregators, that allow clients to collect all distinct combinations of a given set of attributes or collect and run additional aggregation against the corresponding groups of entries.
