query(string $query)

Make a query to the SPARQL endpoint

int

countTriples(string $condition = '?s ?p ?o')

Create a new SPARQL endpoint client

If the query and update endpoints are the same, then you only need to give a single URI.

string**getQueryUri**()

Get the URI of the SPARQL query endpoint

at line 100

string**getUpdateUri**()

Get the URI of the SPARQL update endpoint

at line 109

**getUri**()

at line 126

Result|[Graph](../../EasyRdf/Graph.html) **query**(string $query)

Make a query to the SPARQL endpoint

SELECT and ASK queries will return an object of type EasyRdf\Sparql\Result.

CONSTRUCT and DESCRIBE queries will return an object of type EasyRdf\Graph.

at line 142

int**countTriples**(string $condition = '?s ?p ?o')

Count the number of triples in a SPARQL 1.1 endpoint

Performs a SELECT query to estriblish the total number of triples.

Counts total number of triples by default but a conditional triple pattern can be given to count of a subset of all triples.

[Resource](../../EasyRdf/Resource.html)[]**listNamedGraphs**(string $limit = null)

Get a list of named graphs from a SPARQL 1.1 endpoint

Performs a SELECT query to get a list of the named graphs

at line 188

[Response](../../EasyRdf/Http/Response.html) **update**(string $query)

Make an update request to the SPARQL endpoint

Successful responses will return the HTTP response object

Unsuccessful responses will throw an exception

protected Graph|Result**parseResponseToQuery**(Response|Response $response)

Parse HTTP-response object into a meaningful result-object.

Can be overridden to do custom processing

Proxy function to allow usage of our Client as well as Zend\Http v2.

Zend\Http\Client only accepts an array as first parameter, but our Client wants a name-value pair.
