VERSION
This document describes Attean::API::TermOrVariable version 0.035
SYNOPSIS
use v5.14; use Attean;
DESCRIPTION
This is a Moo role that both terms and variables consume, and is used as a constraint for nodes in triple and quad patterns.
METHODS
- equals( $other )
- Returns true if the referent and $other are value-equal, false otherwise.
- "is_bound"
- Returns true if the referent is bound. Note that in pattern matching,
"undef" may also be used, so typically,
you would need to check
if (defined($term) && $term->is_bound) { ...to check.
