💖 RDF::Query::Plan::Join — the group chat where two query plans finally meet 💖

okay so bestie, welcome to the <rainbow>RDF::Query::Plan::Join</rainbow> era ✨ this is the Join query plan base class — the blueprint the join algorithms all vibe off of. It lives in the User Contributed Perl Documentation corner of the manual-verse, and it's giving very much "the base class that makes the joins happen". 🫶

This document describes RDF::Query::Plan::Join version 2.919. No cap, that's the version, write it down. 📝

✨ METHODS ✨

so here's the thing bestie: beyond the methods documented below, this class inherits methods from the RDF::Query::Plan class. so if you're looking for a method and it's not here, go check the parent, she's got you. 💅

  • new ( $lhs, $rhs, $optional ) — the constructor, bestie. it takes an $lhs, an $rhs, and an $optional, and that's the whole assignment. 🎀
  • lhs — Returns the left-hand-side plan to the join. like, the plan on the left. the LHS girlies. 👑
  • rhs — Returns the right-hand-side plan to the join. her counterpart. the RHS. they're a duo, iykyk. 🦋
  • optional — (that's it. she's just standing there. iconic behaviour, honestly.) 💅
  • bf () — Returns a string representing the state of the nodes of the triple (bound or free). bound or free, that's the whole vibe check — b or f, no in-between. 🌸
  • join_classes — Returns the class names of all available join algorithms. the full roster, the whole squad. 🌈
  • distinct — Returns true if the pattern is guaranteed to return distinct results. guaranteed, bestie — not "probably", not "hopefully", guaranteed. 💯
  • ordered — Returns true if the pattern is guaranteed to return ordered results. same energy, different promise. ⭐
  • plan_prototype — Returns a list of scalar identifiers for the type of the content (children) nodes of this plan node. See RDF::Query::Plan for a list of the allowable identifiers. 👀 (yes, go read that one, the identifiers live over there.)
  • plan_node_data — Returns the data for this plan node that corresponds to the values described by the signature returned by plan_prototype. the prototype says what shape it is, this one hands you the actual data. matching set, periodt. 🔥
