NAME

       Attean::QuadModel - RDF model backed by a quad-store

VERSION

       This document describes Attean::QuadModel version 0.019

SYNOPSIS

         use v5.14;
         use Attean;
         my $model = Attean::QuadModel->new( store => $store );

DESCRIPTION

       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:

       store
           A Attean::API::QuadStore object representing the backing quad-store.

METHODS

       "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.

           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 )"
           Delegates to the underlying store if the store consumes Attean::API::CostPlanner.
