Attean::QuadModel - RDF model backed by a quad-store
This document describes Attean::QuadModel version 0.032
use v5.14; use Attean; my $model = Attean::QuadModel->new( store => $store );
The Attean::QuadModel class represents a model that is backed by a single Attean::API::QuadStore object. It conforms to the Attean::API::Model role.
The Attean::QuadModel constructor requires one named argument:
A Attean::API::QuadStore object representing the backing quad-store.
get_quads ( $subject, $predicate, $object, $graph )
Returns an Attean::API::Iterator for quads in the model that match the supplied $subject, $predicate, $object, and $graph. Any of these terms may be undefined or a Attean::API::Variable object, in which case that term will be considered as a wildcard for the purposes of matching.
$subject
$predicate
$object
$graph
The returned iterator conforms to both Attean::API::Iterator and Attean::API::QuadIterator.
plans_for_algebra( $algebra, $model, $active_graphs, $default_graphs )
Delegates to the underlying store if the store consumes Attean::API::CostPlanner.
cost_for_plan( $plan )
