✨ NAME ✨

Okay so welcome to the Attean...ression(3pm) page from the User Contributed Perl Documentation! 💖 This is Attean::AggregateExpression — representation of aggregate expression trees. It's literally the class for expression trees where the root node is an aggregate op, and I'm obsessed.

🌈 VERSION 🌈

This document describes Attean::AggregateExpression version 0.035. That's the version, bestie. No cap.

🌸 DESCRIPTION 🌸

Okay so Attean::AggregateExpression is the class that represents an expression tree where the root node is an aggregate operation (e.g. SUM(?a) or COALESCE(?a/?b, ?c, 0)). It's giving expression-tree main character energy. 🌈

🎀 ROLES 🎀

This role consumes the Attean::API::AggregateExpression role. Periodt. 💅

👑 ATTRIBUTES 👑

The following attributes exist — full vibe check time:

  • operator — the name of the aggregate operator, from the allowable set: COUNT, SUM, MIN, MAX, AVG, GROUP_CONCAT, SAMPLE. Slay.
  • scalar_vars — a HASH reference of scalar variables. The only scalar variable defined for SPARQL 1.1 is 'seperator' (yes, that exact spelling), a string separator used with the GROUP_CONCAT aggregate. 🍓
  • distinct — a boolean indicating whether the aggregate should operate over distinct term sets, or full multisets. Basically: distinct or not, bestie.
  • variable — a Attean::API::Variable object which will be bound to the produced aggregate value in results. It's the variable catching the aggregate result. 💜
