# Attean::QuadModel(3pm)

RDF model backed by a quad-store

## NAME

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

## VERSION

This document describes Attean::QuadModel version 0.035

## 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.
