RDF::Q...::RDQL(3pm)

💖 RDF::Query::Parser::RDQL — bestie, this is the parser page 💖

okay so welcome to RDF::Query::Parser::RDQL, aka the RDQL parser for RDF::Query ✨ (the manual page header calls it RDF::Q...::RDQL(3pm) from User Contributed Perl Documentation, but you knew that 🫶).

---

🌸 VERSION 🌸

This document describes RDF::Query::Parser::RDQL version 2.919. no cap, that's the version, write it down 🎀

---

✨ METHODS ✨

• new ( $query_object ) — hands you back a brand-new RDF::Query object. that's it, that's the whole vibe 🔥
• parse ( $query ) — takes the RDQL query string you hand it and parses it, giving you back a parse tree 🦋 (yes, it returns a parse tree, that's the deal, slay)
