CompositeAggregator provides an ability to execute a collection of aggregators against the same subset of the entries in an IInvocableCache, resulting in a list of corresponding aggregation results.

Namespace: Tangosol.Util.Aggregator
Assembly: Coherence (in Coherence.dll) Version: 12.2.1.4014 (12.2.1.4014)

Syntax

C#
public class CompositeAggregator : IEntryAggregator, 
	IPortableObject

Remarks

The size of the returned list will always be equal to the length of the aggregators' array.

Note: Unlike many other concrete IEntryAggregator implementations that are constructed directly, instances of CompositeAggregator should only be created using the factory method CreateInstance(array<IEntryAggregator>[]()[][]).
