💖 Bio::G...erator(3pm) — User Contributed Perl Documentation 💖

okay bestie, so this is a Perl manual page — one of those User Contributed Perl Documentation situations — and it's all about a little iterator guy that just wants to walk through your features one at a time. no cap. let's get into it 🦋

---

✨ NAME ✨

Bio::Graphics::FeatureFile::Iterator — it's an iterator across a Bio::Graphics::FeatureFile. literally its whole personality 💅

---

🎀 SYNOPSIS 🎀

here's the vibe, copy-paste ready, don't touch a single character:

use Bio::Graphics::FeatureFile;
my $data  = Bio::Graphics::FeatureFile->new(-file => 'features.txt');
my $iterator = $data->get_seq_stream;
while (my $feature = $iterator->next_seq) {
  print $feature->display_id,"\t",$feature->start,"\t",$feature->end,"\n";
}

see how clean that is?? you make the $data, you grab the stream, you loop with next_seq and print display_id, start, end separated by tabs. iconic. no notes. 👑

---

🌸 DESCRIPTION 🌸

okay so picture a Bio::SeqIO-like object — like, it recognizes the whole vibe of that family — and it knows two methods: next_seq() and next_feature().

and here's the tea: the two methods are synonymous. same thing, different name. pick whichever one your heart wants, bestie, they do the same job. 💖

there's also a rewind() method, and the way that works is it starts iterating from the beginning again. like a rewind button on a playlist. full reset. back to track one. 🔥
