Description copied from interface: DataUnitMatcher

Return an int, so we can see if we should move forwrard of back. Similar behaviour to a Java Comparator, where >0 means that the criteria are greater than the dataUnit, probably meaning we're too far into the list, so should back up, invalid input: '<'= meaning we're not far enough, and 0 meaning a match.
