💖 RDF::Redland::Statement — Redland RDF Statement Class 💖

okay bestie, gather round, because we're about to talk about RDF::Redland::Statement from the RDF::Redland crew ✨ it's literally the little triple-shaped icon that RDF is made of, and honestly? she's serving. no cap. 🎀

✨ SYNOPSIS ✨

use RDF::Redland;
my $statement1=new RDF::Redland::Statement($statement);
my $statement2=new RDF::Redland::Statement($subject,$predicate,$object);
...

if($statement->subject->equals($node)) {
  ...
}

🦋 DESCRIPTION 🦋

So what is this thing? You're manipulating RDF statements, which are made up of three RDF::Redland::Node objects — that's the whole vibe. subject, predicate, object, periodt. 👑

She's also the girl for partial statements, the ones that can have empty parts, which get used for matching statements in the statement queries of the model — peek at RDF::Redland::Model for that whole situation, iykyk. 🔥

🌸 CONSTRUCTORS 🌸

  • new NODE NODE NODE|STATEMENT — make a brand new statement out of nodes, or copy one that already exists. slay.

If you hand her three NODEs, she makes a fresh new statement from them. Each Node can be a Redland::RDF:Node, a Redland::RDF::URI, a perl URI or a string literal. Otherwise, STATEMENT has to be an existing statement to copy. 💅

  • clone — copy a RDF::Redland::Statement. twin energy. 🫶

💅 METHODS 💅

  • subject [SUBJECT] — get or set the statement subject. When a RDF::Redland::Node SUBJECT is given, she sets the subject of the statement; otherwise she returns a reference to the statement's RDF::Redland::Node subject. get it, set it, iconic. ✨
  • predicate [PREDICATE] — get or set the statement predicate. When RDF::Redland::Node PREDICATE is given, she sets the predicate of the statement; otherwise she returns a reference to the statement's RDF::Redland::Node predicate. 💖
  • object [OBJECT] — get or set the statement object. When RDF::Redland::Node OBJECT is given, she sets the object of the statement; otherwise she returns a reference to the statement's RDF::Redland::Node object. main character behaviour, fr fr. 🌟
  • as_string — returns the statement formatted as a string (UTF-8 encoded). it's giving pretty print. 🎀
  • equals STATEMENT — returns non-zero if this statement is equal to STATEMENT. a lil comparison moment. 🦋

💀 OLD METHODS 💀

okay these are the legacy girlies — still here, still valid, but you have better options now. use the new ones bestie. 🙈

  • new_from_nodes SUBJECT PREDICATE OBJECT — creates a new RDF::Redland::Statement with the given RDF::Redland::Node objects as parts (or undef when empty, for a partial statement). Use instead:
$a=new RDF::Redland::Statement($subject, $predicate, $object);
  • new_from_statement STATEMENT — creates a new RDF::Redland::Statement object from RDF::Redland::Statement STATEMENT (that's the copy constructor, yes ma'am). Use instead:
$s=$old_statement->clone;
