All Implemented Interfaces:
EventListener, DoubleSource, IntSource, UpdatableSource
public class CountArrayFunction extends AbstractArrayFunction implements DoubleSource, IntSource
This class computes the number of values in an array taken from a data source. The mean function return always an int value, so it implements the IntSource interface and the standard DoubleSource one.
