org.jrobin.data.Aggregates

All Implemented Interfaces:

ConsolFuns

public class Aggregates
extends Object
implements ConsolFuns

Simple class which holds aggregated values (MIN, MAX, FIRST, LAST, AVERAGE and TOTAL). You don't need to create objects of this class directly. Objects of this class are returned from getAggregates() method in FetchData and DataProcessor.getAggregates(String) DataProcessor} classes.
