RDF::T...atement(3pm)

💖 NAME 💖

RDF::Trine::Statement — it's the class for triples and triple patterns, bestie. That's it, that's the whole vibe. ✨

---

🌸 VERSION 🌸

This doc describes RDF::Trine::Statement version 1.019. Periodt. 💅

✨ METHODS ✨

okay so here's the whole roster, no skips, no skims, we're doing all of them 🫶

• new ( $s, $p, $o ) — hands you back a brand new Triple structure. fresh out the box 🎀
• construct_args — returns a list of arguments that, if you pass them to this class' constructor, will produce a clone of this algebra pattern. like a recipe to rebuild the exact same thing, iconic.
• nodes — returns the subject, predicate and object of the triple pattern. the whole trio, the main character squad 👑
• node_names — returns the method names for accessing the nodes of this statement. so like, the names of the accessors, not the nodes themselves. iykyk.
• subject — returns the subject node of the triple pattern.
• predicate — returns the predicate node of the triple pattern.
• object — returns the object node of the triple pattern.
• as_string — returns the statement in a string form. glow-up into text 💫
• has_blanks — returns true if any of the nodes in this statement are blank nodes. like, even one. 👀
• sse — returns the SSE string for this algebra expression.
• from_sse ( $string, $context ) — parses the SSE-encoded string you hand it and returns a RDF::Trine::Statement object. it's giving reverse uno card 🦋
• type — returns the type of this algebra expression.
• referenced_variables — returns a list of the variable names used in this algebra expression.
• definite_variables — returns a list of the variable names that will be bound after evaluating this algebra expression. future tense, she's planning ahead 💜
• clone — ngl bestie, the original page literally gives this one no description. it's just... standing there. menacingly. 💀 (it's a method, that's all we're told, don't @ me)
• bind_variables ( \%bound ) — returns a new algebra pattern where the variables named in %bound have been replaced by their corresponding bound values. swap szn 🔥
• subsumes ( $statement ) — returns true if this statement will subsume the $statement when matched against a triple store.
• from_redland ( $statement ) — give it a RDF::Redland::Statement object and it'll hand you back a perl-native RDF::Trine::Statement object. translator era 🌈
• rdf_compatible — returns true if and only if the statement can be expressed in RDF. and what does that mean, you ask? the subject of the statement has to be a resource or a blank node; the predicate has to be a resource; and the object has to be a resource, a blank node or a literal. that's the whole checklist, no cap. ✅

okay so important thing though — RDF::Trine::Statement does allow you to create statements that cannot be expressed in RDF. for instance, statements including variables. so like, it will let you cook. it's just not RDF-compatible when you do that. 🚨

and that's the whole page, babe 🫶 this was perl v5.38.2, dated 2024-01-13, straight from User Contributed Perl Documentation. slay, stay hydrated, and go build some triples. 💅✨
