DESCRIPTION

C4::Heading implements a simple class to representing headings found in bibliographic and authority records.

METHODS

new_from_bib_field

  my $heading = C4::Heading->new_from_bib_field($field, $frameworkcode, [, $marc_flavour]);

Given a MARC::Field object containing a heading from a bib record, create a C4::Heading object.

The optional second parameter is the MARC flavour (i.e., MARC21 or UNIMARC); if this parameter is not supplied, it is taken from the Koha application context.

If the MARC field supplied is not a valid heading, undef is returned.

Return the auth_type of the heading.

field

  my $field = $heading->field();

search_form

  my $search_form = $heading->search_form();

Return the "canonical" search form of the heading.

authorities

  my $authorities = $heading->authorities([$skipmetadata]);

Return a list of authority records for this heading. If passed a true value for $skipmetadata, SearchAuthorities will return only authids.

preferred_authorities

  my $preferred_authorities = $heading->preferred_authorities;

Return a list of authority records for headings that are a preferred form of the heading.

INTERNAL METHODS
