Type Parameters:

V - the return value type, for example java.lang.String

T - the value type for the ordering

All Implemented Interfaces:

IDescribable, IAggregator<V,Aggregators.AdvancedMinMaxConsumer<V,T>>, IItemConsumerFactory<Aggregators.AdvancedMinMaxConsumer<V,T>>, IValueBuilder<V,java.util.Iterator<Aggregators.AdvancedMinMaxConsumer<V,T>>>

Enclosing class:

Aggregators

public static class Aggregators.AdvancedMinAggregator<V,T extends java.lang.Comparable<T>>
extends Aggregators.AdvancedMinMaxAggregator<V,T>

This aggregator separates the attribute for which to do the ordering from the attribute to use for accessing the value. It is typically used for getting a specific value from the first event from a collection of events.

For example:
AdvancedMinAggregator<String, IQuantity> aggregator = new AdvancedMinAggregator(myFavouriteAttribute, startTimeAttribute);
