NAME

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

VERSION

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

SYNOPSIS

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

DESCRIPTION

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

METHODS

       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:

           "url"
               The URL of the remote endpoint.

       "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.

       "size"
           Returns the number of statements in the store.

       "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.
