28 This provides a fairly generic iterator that will return records provided
33 use Koha::MetadataIterator;
35 # something that'll return each record
37 my $iterator = Koha::MetadataIterator->new($next_func);
38 while ( my $record = $iterator->next() ) {
39 # do something with $record
50 my $it = new($next_func);
52 Takes a function that will provide the next bit of data.
