RDF::Trine::Serializer - RDF Serializer class


This document describes RDF::Trine::Serializer version 1.019


use RDF::Trine::Serializer;


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


"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".
