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

💖 NAME 💖

RDF::Trine::Iterator::Boolean — bestie, it's the iterator class for boolean query results. That's it, that's the whole vibe. ✨

---

🎀 VERSION 🎀

This doc is describing RDF::Trine::Iterator::Boolean version 1.019. Yes queen, we're on 1.019. 💅

---

🌈 SYNOPSIS 🌈

okay so here's the whole thing in action, no notes:

use RDF::Trine::Iterator::Boolean;

my $iterator = RDF::Trine::Iterator::Boolean->new( [1] );
my $bool = $iterator->get_boolean;
if ($bool) {
       print "Yes.\n";
}

like… it returns a boolean. the boolean is true. you print "Yes.". iconic behaviour honestly. 🫶

✨ METHODS ✨

first things first: on top of everything listed below, this class also inherits methods from the RDF::Trine::Iterator class. so go read that one too, iykyk. 🦋

• new ( \@results, %args ) — makes you a brand new SPARQL Result iterator object. the results have to be a reference to an array holding the results. 🍓
• new ( \&results, %args ) — same deal, new SPARQL Result iterator object, but this time the results are a CODE reference that acts as an iterator: you call it, it hands you the next item, over and over, and once the iterator is all used up it returns undef. sobbing, the closure is tired. 😭
  • $type should be one of: bindings, boolean, graph. those are the options, periodt.
• is_boolean — returns true if the underlying result is a boolean value. a vibe check, basically. ✅
• as_string ( $max_size [, \$count] ) — hands you a string serialization of the stream data. 🔥
• as_xml ( $max_size ) — hands you an XML serialization of the stream data. 💜
• print_xml ( $fh, $max_size ) — prints that XML serialization of the stream data straight to the filehandle $fh. 👑
• as_json ( $max_size ) — hands you a JSON serialization of the stream data. 🌸
• construct_args — returns the arguments you'd need to pass to the stream constructor _new to re-create this stream (assuming the same closure as the first — yes bestie the sentence really does just stop there in the original, i'm not cutting anything, that's genuinely how it ends 💀).
