Attean...ession(3pm)

okay bestie, welcome to the Attean...ession(3pm) page — and yes, it’s filed under User Contributed Perl Documentation. ✨

🎀 NAME 🎀

Attean::Expression — SPARQL Expressions. That’s the name, that’s the vibe. 💅

✨ VERSION ✨

This document describes Attean::Expression version 0.035. 🫶

💅 SYNOPSIS 💅

Here’s the little demo from the page, copied exactly because code is sacred:

use v5.14;
use Attean;

my $binding = Attean::Result->new();
my $value = Attean::ValueExpression->new( value => Attean::Literal->integer(2) );
my $plus = Attean::BinaryExpression->new( children => [$value, $value], operator => '+' );
my $result = $plus->evaluate($binding);
say $result->numeric_value; # 4

And the comment says it all: # 4. Slay. 🔥

🦋 DESCRIPTION 🦋

This is a utility package that defines all the Attean SPARQL expression classes — the ones made of logical, numeric, and function operators, constant terms, and variables. Expressions may be evaluated in the context of an Attean::API::Result object, and they either return an Attean::API::Term object or throw a type error exception. That’s the whole contract, no cap. 💖

The expression classes are:

• Attean::ValueExpression
• Attean::UnaryExpression
• Attean::BinaryExpression
• Attean::FunctionExpression
