Detailed Description

The PluginManager loads and maintains all Soprano plugins.

Normally there is no need to use this class as all important methods have global counterparts in the Soprano namespace.

SOPRANO_EXPORT const Backend * discoverBackendByFeatures	(	BackendFeatures	features,
		const QStringList &	userFeatures = QStringList()
	)

Find a backend plugin by its features.

Parameters:

	features	The features that are requested, a combination of Soprano::BackendFeature flags.
	userFeatures	If features contain Backend::BackendFeatureUser this paramter states the additionally requested user features.

Returns:

a Backend that supports the features defined in features.

Parameters:

	features	The features that are requested.
	userFeatures	If features contain Soprano::BackendFeatureUser this paramter states the additionally requested user features.

Returns:

a backend that supports the features defined in features.

SOPRANO_EXPORT const Backend * discoverBackendByName

(

const QString &

name

)

Find a backend plugin by its name.

Returns:

the backend specified by name or null if could not be found.

the backend specified by name or null if could not be found.

PluginManager::discoverBackendByName()

const Parser* Soprano::PluginManager::discoverParserByName

(

const QString &

name

)

Find a parser plugin by its name.

Returns:

the parser specified by name or null if could not be found.

const Parser* Soprano::PluginManager::discoverParserForSerialization	(	RdfSerialization	serialization,
		const QString &	userSerialization = QString()
	)

Find a Parser instance that is able to parse RDF data serialized as serialization.

Parameters:

	serialization	The requested serialization.
	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:

A Parser plugin that can parse RDF data encoded in the requested serialization or 0 if no such plugin could be found.

const Serializer* Soprano::PluginManager::discoverSerializerByName

(

const QString &

name

)

Find a serializer plugin by its name.

Returns:

the serializer specified by name or null if could not be found.

const Serializer* Soprano::PluginManager::discoverSerializerForSerialization	(	RdfSerialization	serialization,
		const QString &	userSerialization = QString()
	)

Find a Serializer instance that is able to encode RDF data using serialization.

Parameters:

	serialization	The requested serialization.
	userSerialization	If serialization is set to Soprano::SerializationUser this parameter specifies the serialization to use. It allows the extension of the Soprano Serializer interface with new RDF serializations that are not officially supported by Soprano.

Returns:

A Serializer plugin that can serialize RDF data encoded in the requested serialization or 0 if no such plugin could be found.

void Soprano::PluginManager::setPluginSearchPath	(	const QStringList &	path,
		bool	useDefaults = true
	)

Set the plugin search path.

The PluginManager searches a set of folders for installed plugins. Here a plugin consists of a desktop file describing it and the actual plugin library file. For loading custom plugins manually see loadCustomPlugin.

Parameters:

	path	The folders that PluginManager should search for plugin description files.
	useDefaults	If true PluginManager will also search the default plugin paths
