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 non-intersecting 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 EntryAggregator-based methods.
