✨ NAME ✨

RDF::Query::Algebra::Extend — the algebra class for extending the variable projection, bestie 💖

Like, it's giving "we already have a pattern, but now we're gonna add MORE variables to it." Main character energy, honestly.

🌸 VERSION 🌸

This doc describes RDF::Query::Algebra::Extend version 2.919. Yes, she has a version number and yes, she's proud of it 💅

🦋 METHODS 🦋

Okay so first thing first, bestie: beyond everything listed down here, this class also inherits methods from the RDF::Query::Algebra class. So don't come for her saying she's missing stuff — she got it from her parent class, periodt ✨

  • new ( $pattern, \@vars_and_exprs ) — hands you back a brand new Extend structure. Fresh out the box, no cap 🎀
  • construct_args — returns a list of arguments that, if you pass them to this class' constructor, will give you a clone of this exact algebra pattern. It's giving copy-paste but make it a method 🫶
  • pattern — returns the pattern to be sorted. That's it, that's the whole job 💀
  • vars — returns the vars that are getting extended. The whole point of the class, honestly 🌟
  • sse — returns the SSE string for this algebra expression.
  • as_sparql — returns the SPARQL string for this algebra expression.
  • as_hash — returns the query as a nested set of plain data structures... and no objects, okay? We're going raw data structures here. No object glue, just vibes 🌈
  • type — returns the type of this algebra expression. Identity check but for algebra 🔥
  • referenced_variables — returns a list of every variable name used in this algebra expression. The whole squad, accounted for 👑
  • potentially_bound — returns a list of the variable names used in this algebra expression that are gonna bind values while it executes. "potentially" is doing a LOT of heavy lifting in that sentence, ngl 🙈
  • definite_variables — returns a list of the variable names that are for sure bound after this algebra expression gets evaluated. No maybes on this one, fr fr 💖
  • is_solution_modifier — returns true if this node is a solution modifier. Simple as that, bestie ⭐
