NAME

       HTTP::OAI::ListSets - Provide access to an OAI ListSets response

SYNOPSIS

               my $r = $h->ListSets();

               while( my $rec = $r->next ) {
                       print $rec->setSpec, "\n";
               }

               die $r->message if $r->is_error;

METHODS

       $ls = new HTTP::OAI::ListSets
           This constructor method returns a new OAI::ListSets object.

       $set = $ls->next
           Returns either an HTTP::OAI::Set object, or undef, if no more records are available.
           Use $set->is_error to test whether there was an error getting the next record.

           If -resume was set to false in the Harvest Agent, next may return a string (the
           resumptionToken).

       @setl = $ls->set([$set])
           Returns the set list and optionally adds a new set or resumptionToken, $set. Returns
           an array ref of HTTP::OAI::Sets, with an optional resumptionToken string.

       $token = $ls->resumptionToken([$token])
           Returns and optionally sets the HTTP::OAI::ResumptionToken.

       $dom = $ls->toDOM
           Returns a XML::DOM object representing the ListSets response.
