24 Koha::BiblioUtils - contains fundamental biblio-related functions
28 This contains functions for normal operations on biblio records.
30 Note: really, C4::BiblioUtils does the main functions, but the Koha namespace is
31 the new thing that should be used.

48 my $biblio = Koha::BiblioUtils->new($marc_record, [$biblionumber]);
50 Creates an instance of C<Koha::BiblioUtils> based on the marc record. If known,
51 the biblionumber can be provided too.

72 =head2 get_from_biblionumber
74 my $biblio = Koha::BiblioUtils->get_from_biblionumber($biblionumber, %options);
76 This will give you an instance of L<Koha::BiblioUtils> that is the biblio that
85 If true, then the item data will be merged into the record when it's loaded.
89 It will return C<undef> if the biblio doesn't exist.

100 =head2 get_all_biblios_iterator
102 my $it = Koha::BiblioUtils->get_all_biblios_iterator();
104 This will provide an iterator object that will, one by one, provide the
105 Koha::BiblioUtils of each biblio. This will include the item data.
107 The iterator is a Koha::MetadataIterator object.

123 return Koha::MetadataIterator->new($next_func);
126 =head2 get_marc_biblio
128 my $marc = Koha::BiblioUtils->get_marc_biblio($bibnum, %options);
130 This non-class function fetches the MARC::Record for the given biblio number.
131 Nothing is returned if the biblionumber couldn't be found (or it somehow has no
140 If set to true, item data is embedded in the record. Default is to not do this.
