Koha::BiblioUtils::Iterator - iterates over biblios provided by a DBIx::Class::ResultSet
This provides an iterator that gives the MARC::Record of each biblio that's returned by a DBIx::Class::ResultSet that provides a biblionumber,
and marc or marcxml column from the biblioitems table.
use Koha::BiblioUtils::Iterator;
my $rs = $schema->resultset('biblioitems');
my $iterator = Koha::BiblioUtils::Iterator->new($rs);
while (my $record = $iterator->next()) {
// do something with $record
}
my $it = new($sth, option => $value, ...);
Takes a ResultSet to iterate over, and gives you an iterator on it. Optional options may be specified.
Set to true to include item data in the resulting MARC record.
In a scalar context, provides the next MARC::Record from the ResultSet, or undef if there are no more.
In a list context it will provide ($biblionumber, $record).
