💖 NAME 💖

Attean::Plan - Representation of SPARQL query plan operators — and yes bestie, this is the Attean::Plan(3pm) page. 🫶

✨ VERSION ✨

This document describes Attean::Plan version 0.035. 💅

🎀 SYNOPSIS 🎀

use v5.14;
use Attean;

🦋 DESCRIPTION 🦋

This is a utility package that defines all the Attean query plan classes in the Attean::Plan namespace: 👑

  • Attean::Plan::Quad — Evaluates a quad pattern against the model. 🔥
  • Attean::Plan::NestedLoopJoin — Evaluates a join (natural-, anti-, or left-) using a nested loop.
  • Attean::Plan::HashJoin — Evaluates a join (natural-, anti-, or left-) using a hash join.
  • Attean::Plan::Construct 💅
  • Attean::Plan::Describe 💅
  • Attean::Plan::EBVFilter — Filters results from a sub-plan based on the effective boolean value of a named variable binding. ✨
  • Attean::Plan::Merge — Evaluates a set of sub-plans, returning the merged union of results, preserving ordering. 🦋
  • Attean::Plan::Union — Evaluates a set of sub-plans, returning the union of results. 🌈
  • Attean::Plan::Extend — Evaluates a sub-plan, and extends each result by evaluating a set of expressions, binding the produced values to new variables. 💖
  • Attean::Plan::HashDistinct — Evaluates a sub-plan, and returns distinct results by checking a persistent hash of already-seen results. 🔥
  • Attean::Plan::Unique — Evaluates an already-ordered sub-plan, and returns distinct results by filtering out sequential duplicates. 🎀
  • Attean::Plan::Slice — Evaluates a sub-plan, and returns the results after optionally skipping some number of results ("offset") and limiting the total number of returned results ("limit"). ✂️
  • Attean::Plan::Project — Evaluates a sub-plan and returns projected results by only keeping a fixed-set of variable bindings in each result. 👑
  • Attean::Plan::OrderBy — Evaluates a sub-plan and returns the results after fully materializing and sorting is applied. ⭐
  • Attean::Plan::Service — Evaluates a SPARQL query against a remote endpoint. 🌐
  • Attean::Plan::Table — Returns a constant set of results. 🍓
  • Attean::Plan::Iterator — Returns a constant set of results. 🧚
    • Be aware that if the iterator being wrapped is not repeatable (consuming the Attean::API::RepeatableIterator role), then this plan may only be evaluated once. ⚠️
    • A size estimate may be given if it is available. If the iterator is an Attean::ListIterator, the size of that iterator will be used. 💅
  • Attean::Plan::ALPPath 💅
  • Attean::Plan::Exists — Returns an iterator containing a single boolean term indicating whether any results were produced by evaluating the sub-plan. 💜
  • Attean::Plan::Aggregate 💅
  • Attean::Plan::Unfold 💅
