NAME

RDF::Trine::Store::SPARQL - RDF Store proxy for a SPARQL endpoint

This document describes RDF::Trine::Store::SPARQL version 1.019

 use RDF::Trine::Store::SPARQL;

RDF::Trine::Store::SPARQL provides a RDF::Trine::Store API to interact with a remote SPARQL endpoint.

Beyond the methods documented below, this class inherits methods from the RDF::Trine::Store class.

"new ( $url )": Returns a new storage object that will act as a proxy for the SPARQL endpoint accessible via the supplied $url.

"new_with_config ( $hashref )"

Returns a new storage object configured with a hashref with certain keys as arguments.

The "storetype" key must be "SPARQL" for this backend.

The following key must also be used:

"new_with_config ( \%config )": Returns a new RDF::Trine::Store object based on the supplied configuration hashref.

"get_statements ( $subject, $predicate, $object [, $context] )": Returns a stream object of all statements matching the specified subject, predicate and objects. Any of the arguments may be undef to match any value.

"get_pattern ( $bgp [, $context] )": Returns an iterator object of all bindings matching the specified graph pattern.

"get_contexts": Returns an RDF::Trine::Iterator over the RDF::Trine::Node objects comprising the set of contexts of the stored quads.

"add_statement ( $statement [, $context] )": Adds the specified $statement to the underlying model.

"remove_statement ( $statement [, $context])": Removes the specified $statement from the underlying model.

"remove_statements ( $subject, $predicate, $object [, $context])": Removes the specified $statement from the underlying model.

"count_statements ( $subject, $predicate, $object, $context )": Returns a count of all the statements matching the specified subject, predicate, object, and context. Any of the arguments may be undef to match any value.

"supports ( [ $feature ] )": If $feature is specified, returns true if the feature is supported by the store, false otherwise. If $feature is not specified, returns a list of supported features.

"get_sparql ( $sparql )": Returns an iterator object of all bindings matching the specified SPARQL query.
