public interface Fuzzy

This interface specifies the methods which characterize a fuzzy value: getBoundAbs, getBound, getModel. For methods to allow getting of fuzzy information, see FuzzyMutable.
Note that an object which implements Fuzzy is not necessarily actually fuzzy - the values returned maybe 0 error bounds and/or $DistNone.

Field Summary

static int	$DistGaussian Constant to denote a Gaussian (normal) distribution, i.e. with bound representing one standard deviation.
static int	$DistInvalid Constant to denote an invalid (inconsistent) distribution.
static int	$DistNone Constant value to define no distribution model, i.e. an exact value.
static int	$DistUniform Constant to denote a uniform distribution, within two limits, i.e. plus and minus the bound.
static java.lang.String[]	$Names Names for presentation purposes of the Fuzzy modes (in order, but offset by two).

Method Summary

double	getBound() Method to get the relative bound of fuzzy value.
int	getModel() Method to get the error distribution model.
boolean	isExact() Method to determine if the quantity represented is in fact exact.
