Create an instance of GroupAggregator based on a specified extractor and an IEntryAggregator and a result evaluation filter.

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

Syntax

C#
public static GroupAggregator CreateInstance(
	IValueExtractor extractor,
	IEntryAggregator aggregator,
	IFilter filter
)

Parameters

extractor
Type: Tangosol.Util..::.IValueExtractor
An IValueExtractor that will be used to split a set of IInvocableDictionary entries into distinct groups.
aggregator
Type: Tangosol.Net.Cache..::.IEntryAggregator
An underlying IEntryAggregator.
filter
Type: Tangosol.Util..::.IFilter
An optional IFilter object used to filter out results of individual group aggregation results.

Return Value

[Missing <returns> documentation for "M:Tangosol.Util.Aggregator.GroupAggregator.CreateInstance(Tangosol.Util.IValueExtractor,Tangosol.Net.Cache.IEntryAggregator,Tangosol.Util.IFilter)"]

Remarks

If the specified aggregator is an instance of IParallelAwareAggregator, then a parallel-aware instance of the GroupAggregator will be created. Otherwise, the resulting GroupAggregator will not be parallel-aware and could be ill-suited for aggregations run against large partitioned caches.
