RE: ListOrderedMap vs. LinkedHashMap
Thanks for the reply. So from a functionality standpoint, they're the same? if i'm developing in 1.5 JDK, then there's no difference for me, right? -Marc Jörg Schaible [EMAIL PROTECTED] lsag-Solutions.co To mJakarta Commons Users List commons-user@jakarta.apache.org 06/21/2006 01:03 cc PM Subject RE: ListOrderedMap vs. Please respond to LinkedHashMap Jakarta Commons Users List [EMAIL PROTECTED] arta.apache.org [EMAIL PROTECTED] wrote on Wednesday, June 21, 2006 7:37 PM: Hello All - Apologies if this has already been covered.

RE: ListOrderedMap vs. LinkedHashMap
LOM has API extensions that LinkedHashMap can't duplicate. Example: in commons-collections 3.2, put(int, Object, Object) was added to LOM, which allows you to insert a mapping at a particular position. There are others. -Matt --- [EMAIL PROTECTED] wrote: Thanks for the reply.

Re: ListOrderedMap vs. LinkedHashMap
ListOrderedMap is a decorator. It can wrap _any_ type of map and make it ordered. Stephen [EMAIL PROTECTED] wrote: Hello All - Apologies if this has already been covered.
