NAME

Attean::API::MutableModel - Role representing mutable models

VERSION

This document describes Attean::API::MutableModel version 0.027

SYNOPSIS

use v5.14;
use Attean;

DESCRIPTION

This is a Moo role that mutable models consume. It defines the required methods for updating data, and provides default functionality.

ROLES

This role consumes the Attean::API::Model role.

REQUIRED METHODS

Classes consuming this role must provide the following methods:

add_quad( $quad )

Adds the Attean::API::Quad $quad to the model.

remove_quad( $quad )

Removes the Attean::API::Quad $quad from the model.

create_graph( $graph )

Creates a new, empty graph in the model with the Attean::API::BlankOrIRI identifier $graph. If the model does not support empty graphs, this operation may be a no-op.

drop_graph( $graph )

Removes the graph in the model with the Attean::API::BlankOrIRI identifier $graph.

clear_graph( $graph )

Removes all quads that belong to the graph in the model with the Attean::API::BlankOrIRI identifier $graph. If the model does not support empty graphs, this operation may be an alias for drop_graph( $graph ).

METHODS

This role provides default implementations of the following methods:

load_triples( $format, $graph => $data )

Parses the serialized triples contained in the string $data using the $format parser (see "get_parser" in Attean). Triples resulting from parsing are turned into quads using the $graph identifier, and added to the model.

add_iter( $iter )

Adds all the quads from the Attean::API::QuadIterator $iter to the model.

add_list( $graph, @elements )

Adds an rdf:List encoded list of @elements to the model in the $graph. Returns the Attean::API::Blank head of the list.
