From: Jess Robinson Date: Mon, 29 Dec 2008 22:17:37 +0000 (+0000) Subject: Re-ordered method docs to be in a more user-needs-it order. X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=843f6bc16abcae9804ebee10638f7f5dd9361d8c;p=dbsrgits%2FDBIx-Class-Historic.git Re-ordered method docs to be in a more user-needs-it order. Fixed some obj/table mentions in docs to be consistently $source. --- diff --git a/lib/DBIx/Class/ResultSource.pm b/lib/DBIx/Class/ResultSource.pm index 41d5562..3946d7c 100644 --- a/lib/DBIx/Class/ResultSource.pm +++ b/lib/DBIx/Class/ResultSource.pm @@ -33,14 +33,6 @@ retrieved, most usually a table (see L) =pod -=head2 new - - $class->new(); - - $class->new({attribute_name => value}); - -Creates a new ResultSource object.
