NAME

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

VERSION

       This document describes Attean::API::MutableModel version 0.019

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.
