NAME

RDF::Trine::Serializer - RDF Serializer class

CONTENTS

VERSION

This document describes RDF::Trine::Serializer version 1.014

SYNOPSIS



 use RDF::Trine::Serializer;



DESCRIPTION

The RDF::Trine::Serializer class provides an API for serializing RDF graphs (via both model objects and graph iterators) to strings and files.

METHODS

serializer_names Returns a list of valid serializer names for use as arguments to the serializer constructor.
new ( $serializer_name, %options ) Returns a new RDF::Trine::Serializer object for the serializer with the specified name (e.g. rdfxml or turtle). If no serializer with the specified name is found, throws a RDF::Trine::Error::SerializationError exception.

The valid key-values used in %options are specific to a particular serializer implementation. For serializers that support namespace declarations (to allow more concise serialization), use namespaces => \%namespaces in %options, where the keys of %namespaces are namespace names and the values are (partial) URIs. For serializers that support base URI declarations, use base_uri => $base_uri .

negotiate ( request_headers => $request_headers, %options ) Returns a two-element list containing an appropriate media type and RDF::Trine::Serializer object as decided by HTTP::Negotiate. If the request_headers key-value is supplied, the $request_headers is passed to HTTP::Negotiate::choose. The option restrict, set to a list of serializer names, can be used to limit the serializers to choose from. Finally, an <extend > option can be set to a hashref that contains MIME-types as keys and a custom variant as value. This will enable the user to use this negotiator to return a type that isn’t supported by any serializers. The subsequent code will have to find out how to return a representation. The rest of %options is passed through to the serializer constructor.
media_types Returns a list of media types appropriate for the format of the serializer.
serialize_model_to_file ( $fh, $model ) Serializes the $model, printing the results to the supplied filehandle <$fh>.
serialize_model_to_string ( $model ) Serializes the $model, returning the result as a string.
serialize_iterator_to_file ( $file, $iterator ) Serializes the statement objects produced by $iterator, printing the results to the supplied filehandle <$fh>.

Note that some serializers may not support the use of this method, or may require the full materialization of the iterator in order to serialize it. If materialization is required, available memeory may constrain the iterators that can be serialized.

serialize_iterator_to_string ( $iterator ) Serializes the statement objects produced by $iterator, returning the result as a string. Note that the same constraints apply to this method as to serialize_iterator_to_file.
