This constructor method returns a new OAI::ListIdentifiers object. Returns either an HTTP::OAI::Header object, or undef, if there are no more records. Use $rec->is_error to test whether there was an error getting the next record (otherwise things will break). If -resume was set to false in the Harvest Agent, next may return a string (the resumptionToken). Returns the identifier list and optionally adds an identifier or resumptionToken, $idobj. Returns an array ref of HTTP::OAI::Headers. Returns a \s-1XML::DOM\s0 object representing the ListIdentifiers response. Returns and optionally sets the HTTP::OAI::ResumptionToken.
