Attean::API::MutableModel(3pm)

NAME

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

This document describes Attean::API::MutableModel version 0.035

  use v5.14;
  use Attean;

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

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

Classes consuming this role must provide the following methods:

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 ).

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.

"load_triples_from_io( $format, $graph => $data )": Parses the serialized triples read from the filehandle $io 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.
