NAME

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.
