RDF::R...erator(3pm)

💖 RDF::Redland::Iterator — the Redland RDF Iterator Class 💖

okay bestie, we're in the RDF::R...erator(3pm) page — yeah the title got cut off mid-word, it's giving ✨truncated✨, the full name is RDF::Redland::Iterator and it lives in the User Contributed Perl Documentation section of the manual. let's get into it 💅

---

✨ SYNOPSIS ✨

use RDF::Redland;

...
my $iterator=$model->targets_iterator($source_node, $arc_node);
while($iterator && !$iterator->end) {
  my $node=$iterator->current;
  ...
  $iterator->next;
}

🦋 DESCRIPTION 🦋

so basically this class hands you back lists of RDF::Redland::Node objects from any method that returns an RDF::Redland::Iterator. and which methods are those? commonly one of the get_sources_iterator, get_targets_iterator or get_arcs_iterator methods of the RDF::Redland::Model class. iykyk 🫶

why would you even want that? because it's efficient retrieval of long lists of RDF::Redland::Node objects. that's the slay part.

the not-so-slay part: it isn't really very Perl-friendly. no cap, it's just how it is. 😭

if the iterator energy is too much for you, the RDF::Redland::Model class has your back:

• the get_sources, get_targets or get_arcs methods return Perl lists 💖
• the get_source, get_target and get_arc methods return a single arbitrary result 🌸

---

🎀 CONSTRUCTORS 🎀

there are no public constructors, bestie. not one. 😤 you don't build these yourself — they get created and returned from various methods of classes, including RDF::Redland::Model. it's giving "you don't find the iterator, the iterator finds you" 💫

---

👑 METHODS 👑

• end — returns non 0 if the iterator has finished. so like, truthy = done, periodt.
• current — returns the current RDF::Redland::Node object from the iteration, or undef if the iteration is finished. 🙈
• next — moves the iterator on to the next item. returns undef if the iteration is finished. go go go ⭐
• context — returns the context RDF::Redland::Node object from the iteration, or undef if the iteration is finished. 💜

real talk: current and context will both just hand you undef once the iteration is done, so check end (or check for undef) before you start acting like there's a node there, okay? 🫶
