Member Function Documentation

deleteContentByValue()

SMW\SPARQLStore\RepositoryConnectors\FourstoreRepositoryConnector::deleteContentByValue	(		$propertyName,
			$objectName,
			$extraNamespaces = []
	)

Complex SPARQL Update delete operations are not supported in 4Store as of v1.1.3, hence this implementation uses a less efficient method for accomplishing this.

Parameters

$propertyName	string Turtle name of marking property
$objectName	string Turtle name of marking object/value
$extraNamespaces	array (associative) of namespaceId => namespaceUri

Returns

boolean stating whether the operations succeeded

doHttpPost()

SMW\SPARQLStore\RepositoryConnectors\FourstoreRepositoryConnector::doHttpPost

(

$payload

)

Execute a HTTP-based SPARQL POST request according to http://www.w3.org/2009/sparql/docs/http-rdf-update/. The method throws exceptions based on GenericHttpDatabaseConnector::mapHttpRequestError(). If errors occur and this method does not throw anything, then an empty result with an error code is returned.

This method is specific to 4Store since it uses POST parameters that are not given in the specification.

Parameters

$payload

string Turtle serialization of data to send

Returns

boolean

Implements SMW\SPARQLStore\RepositoryConnection.

doQuery()

SMW\SPARQLStore\RepositoryConnectors\FourstoreRepositoryConnector::doQuery

(

$sparql

)

Execute a SPARQL query and return an RepositoryResult object that contains the results. Compared to GenericHttpDatabaseConnector::doQuery(), this also supports the parameter "restricted=1" which 4Store provides to enforce strict resource bounds on query answering. The method also checks if these bounds have been met, and records this in the query result.

Note

The restricted option in 4Store mainly enforces the given soft limit more strictly. To disable/configure it, simply change the soft limit settings of your 4Store server.

Parameters

$sparql

string with the complete SPARQL query (SELECT or ASK)

Returns

RepositoryResult

Implements SMW\SPARQLStore\RepositoryConnection.

doUpdate()

SMW\SPARQLStore\RepositoryConnectors\FourstoreRepositoryConnector::doUpdate

(

$sparql

)

See also

GenericHttpDatabaseConnector::doUpdate

Note

4store 1.1.4 breaks on update if charset is set in the Content-Type header

Since

2.0

Implements SMW\SPARQLStore\RepositoryConnection.
