💖 RDF::Query::Algebra::Path 💖

okay bestie, gather round, because this is the page for RDF::Query::Algebra::Path — the algebra class for path patterns ✨. It ships as part of the User Contributed Perl Documentation and this specific page is RDF::Q...a::Path(3pm), so yeah, that's the manual name, that's the vibe, we move 💅

🌸 VERSION 🌸

This document describes RDF::Query::Algebra::Path version 2.919. That's the number, that's the era, no cap 🎀

✨ METHODS ✨

Real talk first, bestie: beyond the methods documented below, this class inherits methods from the <cyan>RDF::Query::Algebra</cyan> class 🫶. So if you can't find something here, check the parent, it's giving family tree energy.

  • new ( $start, [ $op, @paths ], $end, $graph ) — returns a new Path structure. That's the constructor, that's how you manifest a whole path pattern out of thin air ✨
  • construct_args — returns a list of arguments that, if you pass them to this class' constructor, will produce a clone of this algebra pattern. It's literally the copy-paste cheat code, lowkey iconic 🦋
  • path — returns the path description for this path expression. The main character of the whole object fr fr 👑
  • start — returns the path origin node. Where the journey begins, bestie 🌈
  • end — returns the path destination node. Where the journey ends, and yes the destination is always the best part 😭
  • graph — returns the named graph. Which graph? The named graph. The one it's got 🌸
  • distinguish_bnode_variables — returns a new Path object with blank nodes replaced by distinguished variables. Not mutating the original, we respect boundaries here 💅
  • bounded_length — returns true if the path is of bounded length. That's it. That's the whole vibe check ✅
  • sse — returns the SSE string for this algebra expression. SSE girlies rise 🎀
  • as_sparql — returns the SPARQL string for this algebra expression. If you needed SPARQL out of it, this is the glow-up converter ✨
  • type — returns the type of this algebra expression. Its whole identity, its astrology chart, whatever 💜
  • referenced_variables — returns a list of the variable names used in this algebra expression. Just used, no promises about binding, don't get it twisted 🙈
  • potentially_bound — returns a list of the variable names used in this algebra expression that will bind values during execution. "Potentially" in the name, "will" in the description — that's what the docs say, bestie, I don't make the rules 🫶
  • definite_variables — returns a list of the variable names that will be bound after evaluating this algebra expression. The guaranteed girlies, the ones who actually show up ⭐
🍼 tiny reminder from your bestie: potentially_bound = binds during execution, definite_variables = bound after evaluating. Two different moments in time, two different lists. Periodt.
