Classes in com.tangosol.util.aggregator used by com.tangosol.coherence.dslquery.statement

Class	Description
QueryRecorder	This aggregator is used to produce a QueryRecord object that contains an estimated or actual cost of the query execution for a given filter.
QueryRecorder.RecordType	RecordType enum specifies whether the QueryRecorder should be used to produce a QueryRecord object that contains an estimated or an actual cost of the query execution.

Classes in com.tangosol.util.aggregator used by com.tangosol.util.aggregator

Class	Description
AbstractAggregator	Abstract base class implementation of InvocableMap.EntryAggregator that supports streaming aggregation.
AbstractAsynchronousAggregator	Abstract base class for asynchronous entry aggregators.
AbstractBigDecimalAggregator	Abstract aggregator that processes Number values extracted from a set of entries in a Map and returns a result in a form of a BigDecimal value.
AbstractComparableAggregator	Abstract aggregator that processes values extracted from a set of entries in a Map, with knowledge of how to compare those values.
AbstractDoubleAggregator	Abstract aggregator that processes numeric values extracted from a set of entries in a Map.
AbstractLongAggregator	Abstract aggregator that processes numeric values extracted from a set of entries in a Map.
CompositeAggregator	CompositeAggregator provides an ability to execute a collection of aggregators against the same subset of the entries in an InvocableMap, resulting in a list of corresponding aggregation results.
GroupAggregator	The GroupAggregator provides an ability to split a subset of entries in an InvocableMap into a collection of non-intersecting subsets and then aggregate them separately and independently.
QueryRecorder.RecordType	RecordType enum specifies whether the QueryRecorder should be used to produce a QueryRecord object that contains an estimated or an actual cost of the query execution.
TopNAggregator.PartialResult	The sorted partial result.
