🌸 NAME 🌸

Okay bestie, welcome to the Attean...ression(3pm) page — it’s all about Attean::API::Expression and SPARQL expressions. ✨

Attean::API::Expression — SPARQL expressions 💖

💖 VERSION 💖

This document describes Attean::API::Expression version 0.035, and yes, that’s the version, no cap.

✨ DESCRIPTION ✨

The Attean::API::Expression role defines a common API for SPARQL expressions made of logical, numeric, and function operators, constant terms, and variables. It’s giving very “one role to understand them all” energy. 🫶

Expressions may be evaluated in the context of a Attean::API::Result object, and when that happens they either return a Attean::API::Term object or throw a type error exception. That’s the whole vibe check: term object or type-error exception, periodt.

🦋 ROLES 🦋

This role consumes the Attean::API::DirectedAcyclicGraph role, which provide the following methods:

  • is_leaf
  • walk( prefix => \&pre_cb, postfix => \&pre_cb )
  • cover( prefix => \&pre_cb, postfix => \&pre_cb )

and the following attributes:

  • children

Lowkey iconic that a role can hand you methods and attributes like that. 💅

🎀 ATTRIBUTES 🎀

The following attributes exist:

  • operator — a string indicating the expression operator, like '+' or '||'. Yes bestie, the operator is literally just a string here, iykyk. ⭐

💅 REQUIRED METHODS 💅

The following methods are required by the Attean::API::Expression role:

  • as_string — returns a string serialization of the expression object. It’s the “put it into words” method, fr fr. 🌈

😭 BUGS 😭
