ClassDescriptionCalculates an average for values of any numeric type extracted from a set of entries in a Map in a form of a
BigDecimal
value.Calculates a maximum of numeric values extracted from a set of entries in a Map in a form of aBigDecimal
value.Calculates a minimum of numeric values extracted from a set of entries in a Map in a form of aBigDecimal
value.Calculates an sum for values of any numberic type extracted from a set of entries in a Map in a form of aBigDecimal
value.Calculates a number of values in an entry set.Calculates an average for values of any numeric type extracted from a set of entries in a Map.Calculates a maximum of numeric values extracted from a set of entries in a Map.Calculates a minimum of numeric values extracted from a set of entries in a Map.Sums up numeric values extracted from a set of entries in a Map.Calculates a maximum of numeric values extracted from a set of entries in a Map.Calculates a minimum of numeric values extracted from a set of entries in a Map.Sums up numeric values extracted from a set of entries in a Map. -
ClassDescriptionThis aggregator is used to produce a
QueryRecord
object that contains an estimated or actual cost of the query execution for a given filter.RecordType enum specifies whether theQueryRecorder
should be used to produce aQueryRecord
object that contains an estimated or an actual cost of the query execution. -
ClassDescriptionA marker
EntryAggregator
wrapper class that allows for an asynchronous invocation of the underlying aggregator.RecordType enum specifies whether theQueryRecorder
should be used to produce aQueryRecord
object that contains an estimated or an actual cost of the query execution. -
ClassDescriptionAbstract base class implementation of
InvocableMap.EntryAggregator
that supports streaming aggregation.Abstract base class for asynchronous entry aggregators.Abstract aggregator that processesNumber
values extracted from a set of entries in a Map and returns a result in a form of aBigDecimal
value.Abstract aggregator that processes values extracted from a set of entries in a Map, with knowledge of how to compare those values.Abstract aggregator that processes numeric values extracted from a set of entries in a Map.Abstract aggregator that processes numeric values extracted from a set of entries in a Map.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.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.RecordType enum specifies whether theQueryRecorder
should be used to produce aQueryRecord
object that contains an estimated or an actual cost of the query execution.The sorted partial result.
