Attean...::LMDB(3pm)

💖 AtteanX::Store::LMDB — the manual page, but make it slay 💖

okay so bestie, you're reading the User Contributed Perl Documentation for AtteanX::Store::LMDB and honestly? it's giving storage. it's giving persistence. it's giving RDF quads living their best life on disk. let's get into it 🦋

---

✨ NAME ✨

AtteanX::Store::LMDB — an LMDB-based RDF store. periodt. that's the whole vibe. 💅

---

🌸 VERSION 🌸

This document describes AtteanX::Store::LMDB version 0.001. tiny version number, huge potential, main character energy fr fr 👑

---

🎀 SYNOPSIS 🎀

the whole entire "how do I even use this" moment, and it's literally one line:

use AtteanX::Store::LMDB;

that's it. that's the post. iconic. ✨

---

🦋 DESCRIPTION 🦋

So like, AtteanX::Store::LMDB gives you a persistent quad-store that's built on top of LMDB. persistent means your data actually stays there instead of ghosting you the second the process exits. quad-store means it holds RDF quads. it's all very "your data but it remembers you" 🥹💖

---

💅 METHODS 💅

okay so real talk — beyond the methods listed below, this class also inherits methods from the Attean::API::QuadStore class. so if you don't see it here, check there, iykyk 🫶

• new () — hands you back a brand-new LMDB-backed store object. fresh out the box, no cap. ✨
• size — tells you how many quads are chillin' in the store. a headcount, basically. 🧮
• get_quads ( $subject, $predicate, $object, $graph ) — returns a stream object of every statement that matches the $subject, $predicate, $object, and $graph you asked for. and here's the cute part: any of those arguments can be undef to match any value. wildcard mode activated 🌈
• get_graphs — returns an iterator over the Attean::API::Term objects that make up the set of graphs of the stored quads. it's giving "who are all my graphs" energy 👑
• add_quad ( $quad ) — adds the $quad you pass in to the underlying model. put it in, bestie 🫳✨
• remove_quad ( $statement ) — removes the $statement you pass in from the underlying model. bye bye, don't let the door hit you 💀
• create_graph( $graph ) — heads up: this is a no-op function for the memory quad-store. it literally does nothing. it's the "seen 2:47 AM" of methods 🙈
• drop_graph( $graph ) — removes all quads with the given $graph. gone. deleted. not coming back 😭
• clear_graph( $graph ) — removes all quads with the given $graph. same energy as above, fr fr 🧹
