org.custommonkey.xmlunit.examples.FloatingPointTolerantDifferenceListener

All Implemented Interfaces:

DifferenceListener

public class FloatingPointTolerantDifferenceListener
extends TextDifferenceListenerBase

Expects texts to be floating point numbers and treats them as identical if they only differ by a given tolerance value (or less).

This implementation uses an absolute tolerance value value for all numbers encountered, calculating a difference relative to one of the numbers compared might be more appropriate in general.
