extends java.io.Serializable

An EntryAggregator represents processing that can be directed to occur against some subset of the entries in an InvocableMap, resulting in a aggregated result. Common examples of aggregation include functions such as min(), max() and avg(). However, the concept of aggregation applies to any process that needs to evaluate a group of entries to come up with a single answer.

Method Summary
`java.lang.Object` | `aggregate(java.util.Set setEntries)` Process a set of InvocableMap.Entry objects in order to produce an aggregated result.
