✨ NAME ✨

RDF::Query::Algebra::Quad — bestie, this is the algebra class for Quad patterns 💖

🦋 VERSION 🦋

This doc describes RDF::Query::Algebra::Quad version 2.919. yes, we're on the record, no cap.

💅 METHODS 💅

okay so first thing, before literally anything else: on top of all the methods listed below, this class inherits methods from the RDF::Query::Algebra class. so go peep that one too, iykyk 🫶

  • new ( $s, $p, $o, $g ) — hands you a brand new Quad structure back. four args: subject, predicate, object, graph. iconic.
  • as_sparql — returns the SPARQL string for this algebra expression. it's giving "translate my whole vibe into SPARQL" ✨
  • as_hash — returns the query as a nested set of plain data structures, like with no objects at all. just raw data vibes.
  • referenced_blanks — returns a list of the blank node names used in this algebra expression. all the anon besties, accounted for 🌸
  • qualify_uris ( \%namespaces, $base_uri ) — returns a new algebra pattern where every referenced Resource node that's representing a QName (ns:local) gets qualified using the %namespaces you supplied. glow-up for your QNames 💅
  • bf () — returns a string representing the state of the nodes of the triple: bound or free. that's the whole vibe check, right there.
  • distinguish_bnode_variables — returns a new Quad object, except blank nodes got replaced by distinguished variables. bnodes, but make it identifiable 👑
  • label ( $label => $value ) — sets the named $label to $value for this quad object. and if you don't pass a $value? it just returns the current label value, or undef if none exists. so it's a setter and a getter, unbothered, multifunctional 😭
