+=head2 Instance Methods
-Object-oriented class that encapsulates authority records in Koha.
+=head3 get_usage_count
-=head1 DESCRIPTION
+ $count = $self->get_usage_count;
-Authority data.
+ Returns the number of linked biblio records.

-__PACKAGE__->mk_accessors(qw( authid authtype record marcflavour ));
+ my @biblios = $self->linked_biblionumbers({
+ [ max_results => $max ], [ offset => $offset ],
+ });
-=head2 new
+ Returns an array of biblionumbers.
- my $auth = Koha::Authority->new($record);
+=cut
-Create a new Koha::Authority object based on the provided record.

+=head3 controlled_indicators
- my $self = $class->SUPER::new( { record => $record });
+ Some authority types control the indicators of some corresponding
+ biblio fields (especially in MARC21).
+ For example, if you have a PERSO_NAME authority (report tag 100), the
+ first indicator of biblio field 600 directly comes from the authority,
+ and the second indicator depends on thesaurus settings in the authority
+ record. Use this method to obtain such controlled values. In this example
+ you should pass 600 in the biblio_tag parameter.

+ my $result = $self->controlled_indicators({
+ record => $auth_marc, biblio_tag => $bib_tag
+ });
+ my $ind1 = $result->{ind1};
+ my $ind2 = $result->{ind2};
+ my $subfield_2 = $result->{sub2}; # Optional subfield 2 when ind==7
+
+ If an indicator is not controlled, the result hash does not contain a key
+ for its value. (Same for the sub2 key for an optional subfield $2.)
-=head2 get_from_authid
+ Note: The record parameter is a temporary bypass in order to prevent
+ needless conversion of $self->marcxml.
- my $auth = Koha::Authority->get_from_authid($authid);
+=cut
-Create the Koha::Authority object associated with the provided authid.
