Direct Known Subclasses:

DistanceAggregateResult, RangeAggregateResult, StatsAggregateResult, TimeSeriesAggregateResult

public abstract class AggregateResult
extends java.lang.Object

This abstract class represents the result of an arbitrary aggregate function. All AggregateResult objects operate over a particular field name, with a particular kind of aggregate function, and provide a count of the number of field values included in the aggregate calculation. Individual subclass implementations will augment this basic information with specific details relevant to the kind of aggregation performed.
