\class Parser parser.h Soprano/Parser
Soprano.Parser defines the interface for a Soprano RDF parser plugin. Each parser plugin may support multiple RDF serializations (supportedSerializations()). Usage Using a Parser is straightforward. One starts by getting a plugin that supports the requested RDF data serialization:
Soprano.Parser* p = Soprano.PluginManager.instance()->discoverParserForSerialization( Soprano.SerializationRdfXml ); Then parsing RDF data is done in a single method call resulting in a StatementIterator over the resulting graph (since parsers may support multiple serializations one always needs to provide the serialization type unless a parser plugin support autodetection).
Soprano.StatementIterator it = p->parseFile( "myrdffile.rdf", Soprano.SerializationRdfXml ); See also soprano_writing_plugins

Parse an RDF model which has been serialized in a file,
using the supplied baseURI to resolve any relative URI references.
The default implementation simply calls parseStream() on an opened QFile instance. filename - The name (path) of the file to parse baseUri - The base URI to be used for relative references. serialization - The serialization used in the file. userSerialization - If serialization is set to Soprano.SerializationUser this parameter specifies the serialization to use. It allows the extension of the %Soprano Parser interface with new RDF serializations that are not officially supported by %Soprano. Returns An iterator that iterates over the result statements. |

Read a serialized RDF model from a test stream,
using the supplied baseURI to resolve any relative URI references.
stream - The text stream to read the serialized RDF data from. baseUri - The base URI to be used for relative references. serialization - The serialization used for the string data from the stream. userSerialization - If serialization is set to Soprano.SerializationUser this parameter specifies the serialization to use. It allows the extension of the %Soprano Parser interface with new RDF serializations that are not officially supported by %Soprano. Returns An iterator that iterates over the result statements. |

Parse an RDF model which has been serialized into a string,
using the supplied baseURI to resolve any relative URI references.
The default implementation simply calls parseStream(). data - The serialized RDF string. baseUri - The base URI to be used for relative references. serialization - The serialization used for the string data. userSerialization - If serialization is set to Soprano.SerializationUser this parameter specifies the serialization to use. It allows the extension of the %Soprano Parser interface with new RDF serializations that are not officially supported by %Soprano. Returns An iterator that iterates over the result statements. |

The serialiazation types supported by this parser. Returns A combination of Soprano.RdfSerialization types. If the list contains Soprano.SerializationUser the parser supports additional RDF serialiazations not officially supported by %Soprano. |
|
A parser can support additional RDF serializations that are not defined in Soprano.RdfSerialization.
In that case supportedSerializations() has to include Soprano.SerializationUser.
The default implementation returns an empty list. Returns A list of supported user RDF serializations. |

Check if a plugin supports a specific serialization.
s - The requested serialization. userSerialization - If serialization is set to Soprano.SerializationUser this parameter specifies the requested serialization. It allows the extension of the %Soprano Parser interface with new RDF serializations that are not officially supported by %Soprano. Returns true if the parser is able to parse RDF data encoded in serialization s, false otherwise. |
