RDF::Q...Project(3pm)

💅 RDF::Query::Plan::Project

okay bestie, gather round, because this is the RDF::Query::Plan::Project manual page (that's the RDF::Q...Project(3pm) one, from the User Contributed Perl Documentation corner of the universe) and it's lowkey iconic. ✨

This class is the executable query plan for Projects. That's it, that's the whole vibe. She plans, she executes, she projects. Main character energy fr fr. 🎀

🌸 VERSION

This doc describes RDF::Query::Plan::Project version 2.919. No cap, that's the number, don't @ me. 💜

✨ METHODS ✨

Real talk: beyond the methods listed down below, this class inherits methods from the RDF::Query::Plan class. So if you're looking for something and it's not here, check the parent, she's holding. 🫶

• new ( $plan, \@keys ) — constructor behavior, she's born. 👑
• execute ( $execution_context ) — makes it go, bestie. Runs the plan in the given execution context. 🔥
• next — gimme the next result. One at a time, we're not greedy. 💖
• close — we're done here, wrap it up, thank u next. 🦋
• pattern — Returns the query plan that will be used to produce the data to be projected. So like, this is the thing feeding the projection. The source, the muse, the provider. 😌
• distinct — Returns true if the pattern is guaranteed to return distinct results. Guaranteed, meaning fr fr no duplicates, pinky promise. ✨
• ordered — Returns true if the pattern is guaranteed to return ordered results. Guaranteed order, she's organized, she has a system. 🎀
• plan_node_name — Returns the string name of this plan node, suitable for use in serialization. It's giving "name tag at the party." 📛
• plan_prototype — Returns a list of scalar identifiers for the type of the content (children) nodes of this plan node. See RDF::Query::Plan for a list of the allowable identifiers. Basically the blueprint of what kind of children nodes can show up here. 👀
• plan_node_data — Returns the data for this plan node that corresponds to the values described by the signature returned by plan_prototype. So plan_prototype says what shape, and this one hands over the actual stuff. Match made in heaven. 💞
• graph ( $g ) — takes a graph $g. Do with that what you will, she's documented and she's moving on. 🌈
• explain — Returns a string serialization of the plan appropriate for display on the command line. It's the "explain urself" method, except she does it in a cute lil string for ur terminal. 💅
