💖 RDF::Query::Algebra::Filter — the manual, but make it cute 💖

okay bestie, pull up a chair 🫶 you're looking at RDF::Query::Algebra::Filter, a Perl module from the RDF::Query world (the man page header shortens the whole thing to RDF::Q...:Filter(3pm) because apparently even man pages have a character limit, tragic 😭). It's the algebra class for Filter expressions — the thing that goes "nah, only keep the solutions that match this condition ✨". She's giving main character energy in your query pipeline, no cap.

🌸 VERSION 🌸

This doc describes RDF::Query::Algebra::Filter version 2.919. Iconic. Locked in. 💅

✨ METHODS ✨

okay so first things first: beyond everything listed down below, this class also inherits methods from the RDF::Query::Algebra class. So if you don't see it here, bestie, go check the parent 👑 (iykyk).

  • new ( $expression, $pattern ) — hands you back a brand new Filter structure. That's it, that's the vibe. 🎀
  • construct_args — returns a list of arguments that, if you pass them to this class' constructor, will produce a clone of this algebra pattern. yes, it's giving "gimme the recipe to remake myself" and honestly? slay. 🦋
  • expr — returns the filter expression. 🌟
  • pattern — returns the filter pattern. 🧚
  • 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 by "plain" I mean no objects, bestie, just raw data. 💀
  • as_spin ( $model ) — adds statements to the given model to represent this algebra object in the SPARQL Inferencing Notation (that's <http://www.spinrdf.org/> if you wanna peek 👀). 💜
  • type — returns the type of this algebra expression. 🎀
  • referenced_variables — returns a list of the variable names used in this algebra expression. 💖
  • potentially_bound — returns a list of the variable names used in this algebra expression that will bind values during execution. lowkey important. 🌈
  • definite_variables — returns a list of the variable names that will be bound after evaluating this algebra expression. 🫶
  • is_solution_modifier — returns true if this node is a solution modifier. periodt. ⭐
