NAME

Attean::DatasetModel - RDF model that restricts the dataset of a sub-model

VERSION

This document describes Attean::DatasetModel version 0.039

SYNOPSIS

use v5.14;
use Attean;
my $model = Attean::DatasetModel->new( model => $model, graphs => \@named_graphs );

DESCRIPTION

The Attean::DatasetModel class represents a model that is backed by a sub-model. It restricts the available named graphs of the sub-model to only those configured during construction.

This class conforms to the Attean::API::Model role.

The Attean::DatasetModel constructor requires two named arguments:

model

A Attean::API::Model object representing the sub-model.

graphs

An array reference of Attean::API::IRI objects, enumerating the acceptable named graphs that can be queried.

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.
