Description
Class Summary  

AbstractAggregator  Abstract base class implementation of InvocableMap.EntryAggregator that supports parallel aggregation. 
AbstractBigDecimalAggregator  Abstract aggregator that processes Comparable 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. 
BigDecimalAverage  Calculates an average for values of any numberic type extracted from a set of entries in a Map in a form of a BigDecimal value. 
BigDecimalMax  Calculates a maximum of numeric values extracted from a set of entries in a Map in a form of a BigDecimal value. 
BigDecimalMin  Calculates a minimum of numeric values extracted from a set of entries in a Map in a form of a BigDecimal value. 
BigDecimalSum  Calculates an sum for values of any numberic type extracted from a set of entries in a Map in a form of a BigDecimal value. 
ComparableMax  Calculates a maximum among values extracted from a set of entries in a Map. 
ComparableMin  Calculates a minimum among 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. 
CompositeAggregator.Parallel  Parallel implementation of the CompositeAggregator. 
Count  Calculates a number of values in an entry set. 
DistinctValues  Return the set of unique values extracted from a set of entries in a Map. 
DoubleAverage  Calculates an average for values of any numberic type extracted from a set of entries in a Map. 
DoubleMax  Calculates a maximum of numeric values extracted from a set of entries in a Map. 
DoubleMin  Calculates a minimum of numeric values extracted from a set of entries in a Map. 
DoubleSum  Sums up numeric values extracted from a set of entries in a Map. 
GroupAggregator  The GroupAggregator provides an ability to split a subset of entries in an InvocableMap into a collection of nonintersecting subsets and then aggregate them separately and independently. 
GroupAggregator.Parallel  Parallel implementation of the GroupAggregator. 
LongMax  Calculates a maximum of numeric values extracted from a set of entries in a Map. 
LongMin  Calculates a minimum of numeric values extracted from a set of entries in a Map. 
LongSum  Sums up numeric values extracted from a set of entries in a Map. 
PriorityAggregator  PriorityAggregator is used to explicitly control the scheduling priority and timeouts for execution of EntryAggregatorbased methods. 
QueryRecorder  This parallel aggregator 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. 
ReducerAggregator  The ReducerAggregator is used to implement functionality similar to CacheMap.getAll(Collection) API. 
Contains concrete InvocableMap.EntryAggregator
implementations.
