public static interface InvocableMap.EntryAggregator
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.
