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

💖 RDF::Trine::Store::Hexastore — the perl manpage but make it cute 💖

okay bestie, welcome to RDF::Trine::Store::Hexastore(3pm), a page from the User Contributed Perl Documentation section of the manual. yes the title got truncated to RDF::T...astore because manpages are dramatic like that, but we're doing the whole thing, no skips, periodt. ✨

---

🌸 VERSION 🌸

This document describes RDF::Trine::Store::Hexastore version 1.019. that's the vibe check result, locked in. 🎀

---

🦋 SYNOPSIS 🦋

the whole entire "how do I even start" moment:

use RDF::Trine::Store::Hexastore;

that's it. that's the synopsis. iconic, honestly. 💅

---

✨ DESCRIPTION ✨

RDF::Trine::Store::Hexastore gives you an in-memory triple-store built on six-way indexing — the technique that got popularized by Hexastore. six ways of indexing everything so your lookups are fast. main character indexing energy, fr fr. 🔥

---

👑 METHODS 👑

so besides all the methods we're about to list below, this class also inherits methods from the RDF::Trine::Store class. family inheritance, we love to see it. 🫶

• new () — hands you a brand new storage object. fresh out the box, no cap. 🌸
• new_with_config ( $hashref ) — hands you a new storage object that's been configured using a hashref, with certain keys passed in as arguments.

the storetype key must be Hexastore for this backend. like, mandatory. non-negotiable. 🚨

This module can also initialize the store from a file or a URL, and in that case you can use a sources key. That key holds an arrayref of hashrefs. To load a file, you give the file name with a file key inside the hashref; to load a URL, use url. Check the example below bestie. On top of that, these keys are also available:

• syntax — the syntax of the parsed file or URL.
• base_uri — the base URI to be used for a parsed file.

Here's the example, and it sets up a Hexastore store from a local file and a remote URL at the same time. multitasking queen:

my $store = RDF::Trine::Store->new_with_config( {
    storetype => 'Hexastore',
    sources => [
        {
            file => 'test-23.ttl',
            syntax => 'turtle',
        },
        {
            url => 'http://www.kjetil.kjernsmo.net/foaf',
            syntax => 'rdfxml',
        }
]});

• store ( $filename ) — writes the triples data out to a file specified by $filename. and the good news? that data can be read right back in later with the load method. round trip, slay. 💾
• load ( $filename ) — returns a brand new Hexastore object with triples data pulled from the specified file. 🍓
• temporary_store — returns a temporary (empty) triple store. a lil blank canvas, a fresh start, we love her. ✨
• get_statements ($subject, $predicate, $object [, $context] ) — returns a stream object of all the statements matching the subject, predicate and objects you specified. any of those arguments can be undef to match literally any value. wildcard behavior, we stan. 💜
• get_pattern ( $bgp [, $context] ) — returns a stream object of all the bindings matching the specified graph pattern. 🦋
• supports ( [ $feature ] ) — if you pass $feature, it returns true when the store supports that feature and false when it doesn't. if you don't pass $feature, it returns a list of the supported features instead. yes-or-no or the whole menu, your call. 👑
• get_contexts — (no description in the original, she's mysterious like that 💀)
• add_statement ( $statement [, $context] ) — adds the specified $statement to the underlying model. drop it in, bestie. 🌈
• remove_statement ( $statement [, $context]) — removes the specified $statement from the underlying model. gone, bye. 🙈
• remove_statements ( $subject, $predicate, $object [, $context]) — removes the specified $statement from the underlying model. yes, the original really does say $statement here even though the signature lists subject/predicate/object — we report, we don't rewrite. 💀
• etag — returns an Etag suitable for use in an HTTP Header. headers but make it fashionable. 🎀
• nuke — permanently removes all the data in the store. all of it. every last triple. no undo button, no take-backs, this is not a drill. 💥
• count_statements ($subject, $predicate, $object) — returns a count of all the statements matching the specified subject, predicate and objects. any of the arguments may be undef to match any value. counting era. ⭐
