29 | |
30 | See L<DBIx::Class::Schema::Loader::Base> |
31 | |
32 | =head1 DESCRIPTION |
33 | |
34 | This is the base class for L<DBIx::Class::Schema::Loader::Base> classes for |
35 | DBI-based storage backends, and implements the common functionality between them. |
36 | |
37 | See L<DBIx::Class::Schema::Loader::Base> for the available options. |
38 | |
39 | =head1 METHODS |
40 | |
41 | =head2 new |
42 | |
43 | Overlays L<DBIx::Class::Schema::Loader::Base/new> to do some DBI-specific |
44 | things. |
