InvocableMap.ParallelAwareAggregator (Oracle® Coherence Java API Reference)

Type Parameters:

K - the type of the Map entry keys

V - the type of the Map entry values

P - the type of the intermediate result during the parallel stage

R - the type of the value returned by the ParallelAwareAggregator

All Superinterfaces:

InvocableMap.EntryAggregator<K,V,R>, Serializable

Enclosing interface:

InvocableMap<K,V>
```
@Deprecated
public static interface InvocableMap.ParallelAwareAggregator<K,V,P,R>
extends InvocableMap.EntryAggregator<K,V,R>
```
Deprecated.
This interface was deprecated in Coherence 12.2.1 and might be removed in a future release. Use InvocableMap.StreamingAggregator instead.

A ParallelAwareAggregator is an advanced extension to EntryAggregator that is explicitly capable of being run in parallel, for example in a distributed environment.

```
InvocableMap.EntryAggregator<K,V,P> getParallelAggregator()
```
    Deprecated.
    
    Get an aggregator that can take the place of this aggregator in situations in which the InvocableMap can aggregate in parallel.
    If the returned aggregator is a InvocableMap.ParallelAwareAggregator.PartialResultAggregator, the partial results of the aggregation may be further aggregated where optimal.
    
    Returns:
    
    the aggregator that can be run in parallel
  - aggregateResults
```
R aggregateResults(Collection<P> collResults)
```
    Deprecated.
    
    Aggregate the results of the partial aggregations into a final result.
    
    Parameters:
    
    collResults - the partial aggregation results
    
    Returns:
    
    the aggregation of the partial aggregation results
