✨ RDF::Query::Algebra::Sequence — the manual, but make it cute ✨

okay so bestie, welcome to RDF::Q...equence(3pm) 💖 (the full name is RDF::Query::Algebra::Sequence, the terminal just gets shy and truncates it, iykyk). This is Perl's User Contributed Perl Documentation for it, and it's literally the algebra class for a sequence of algebra operations. A whole little squad of ops, lined up in order. slay. 👑

🌸 VERSION 🌸

This doc describes RDF::Query::Algebra::Sequence version 2.919. that's the vibe check, and it passed. ✨

🎀 METHODS 🎀

Okay so like, beyond the methods we're about to spill the tea on below, this class also inherits methods from the RDF::Query::Algebra class. so there's lore you gotta go read elsewhere. 👀

  • new ( @patterns ) — gives you back a brand new Sequence structure. fresh out the box, no cap. 🦋
  • construct_args — hands you a list of arguments that, if you pass them to this class' constructor, will produce a clone of this algebra pattern. it's giving "here's how you re-make me." 💅
  • patterns — returns the list of patterns that belong to this sequence. the whole crew. 🫶
  • sse — returns the SSE string for this algebra expression. stringified and iconic.
  • as_sparql — returns the SPARQL string for this algebra expression. yes queen, give us the SPARQL. 🌈
  • as_hash — returns the query as a nested set of plain data structures. no objects. just plain lil data, unbothered, moisturized, in its lane. 🍓
  • type — returns the type of this algebra expression. identity crisis? never heard of her. ⭐
  • referenced_variables — returns a list of the variable names used in this algebra expression. everyone who got name-dropped. 💜
  • potentially_bound — returns a list of the variable names used in this algebra expression that will bind values during execution. potentially bound. manifesting. 🙈
  • definite_variables — returns a list of the variable names that will be bound after evaluating this algebra expression. no maybes, these ones are committed. periodt. 🔥
  • clone — (the original just lists it here, bestie, so I'm not gonna invent lore for it. take it as read. 💀)
  • bind_variables ( \%bound ) — returns a new algebra pattern with the variables named in %bound replaced by their corresponding bound values. glow-up via substitution. ✨
  • check_duplicate_blanks — returns true if blank nodes respect the SPARQL rule of no blank-label re-use across BGPs. otherwise it throws an RDF::Query::Error::QueryPatternError exception. so like, behave, or it WILL throw hands. 😭
