Minor refactoring of ERXStringUtilities.distance(). #312#314
Merged
Conversation
This is really just a cut and paste of the implementation of 'double distance(String, String)' into 'int levenshteinDistance(String, String)', and a replacement of the body of the former method with a call to the latter. (We don't even need a cast to go from int to double.) We also take the opportunity to deprecate distance(), and mark it for potential future removal. Note that distance() still passes all the tests in ERXStringUtilitiesTest.testDistance().

As described in #312, these commits add a new method,
levenshteinDistance()(which returns anint), implements that method with the body ofdistance(), and then changes the implementation ofdistance()to use the new method. Further, we deprecatedistance()(because it unnecessarily returns adoubleinstead of anint), fix the Javadocs that originally documenteddistance(), and updateERXStringUtilitiesTestto show that none of this makes any functional difference.
