NAME
PurpleWiki::Sequence - Generates sequences for node IDs
SYNOPSIS
use PurpleWiki::Sequence;
my $dataDir = '/wikidb';
my $url = 'http://purplewiki.blueoxen.net/cgi-bin/wiki.pl';
my $sequence = new PurpleWiki::Sequence($dataDir);
$sequence->getNext;DESCRIPTION
Generates IDs in base 36 (10 digits + 26 uppercase alphabet) for use as node IDs.
METHODS
new($datadir, [remotesequence])
Constructor. $datadir contains the Wiki configuration/database directory. There, PurpleWiki::Sequence stores the last used ID and an index of node IDs to fully qualified URLs (used by Transclusion.pm).
Optionally takes a second argument which points to a URL from which nids can be retrieved. This is an experimental feature and should not be relied upon to stick around.
getNext($url)
Returns the next ID, increments and updates the last used ID appropriately. If $url is passed, also updates the NID to URL index.
getURL($nid)
Returns the URL in the index associated with the given NID, or undef if there isn't one.
