$li = new OAI::ListIdentifiers

This constructor method returns a new OAI::ListIdentifiers object.

$rec = $li->next

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).

@il = $li->identifier([$idobj])

Returns the identifier list and optionally adds an identifier or resumptionToken, $idobj. Returns an array ref of HTTP::OAI::Headers.

$dom = $li->toDOM

Returns a XML::DOM object representing the ListIdentifiers response.

$token = $li->resumptionToken([$token])

Returns and optionally sets the HTTP::OAI::ResumptionToken.
