All Implemented Interfaces:
nz.org.riskscape.engine.rl.agg.AggregationFunction
public class BucketRange extends Object implements nz.org.riskscape.engine.rl.agg.AggregationFunction

Aggregate function for applying the given select aggregate expression to rows whose picked value falls between a range of user-defined numbers. This function is essentially a wrapper around the BucketFunction, but with a simpler, terse argument syntax that is optimized for bucketing according to values within a range.
