I am trying to extend the functionality of IntRange based on Martin Fowler's Analysis Pattern of "Range" to model a street Address Range.
http://www.martinfowler.com/ap2/range.html So for example, a street "Joe Blow St" will have an associated AddressRange of 2000-2999 etc... I wanted to extend IntRange and add the functions mentioned in the "Range" pattern and add some more: for e.g. to check if its valid range (ideally in a constructor or a isValid() method). Right now I am forced into cut pasting IntRange in my AddressRange class which extends org.apache.commons.lang.math.Range. I would ideally like to just extend IntRange. Why are these classes finalized? Is it just because of security as David Wheeler says in #8 http://www.dwheeler.com/secure-programs/Secure-Programs-HOWTO/java.html Btw, Commons is cool! I am also using MultiKey and MultiKeyMap to figure out errors in street attributes. Thanks in advance! ____________________________________________________ Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
