SYNOPSIS

         use v5.14;
         use Attean;
         my $client = Attean::SPARQLClient->new(endpoint => 'http://example.org/sparql');
         my $results = $client->query('SELECT * WHERE { ?s ?p ?o }');
         while (my $r = $results->next) {
           say $r->as_string;
         }

DESCRIPTION

       The Attean::SPARQLClient class provides an API to execute SPARQL queries against a remote
       SPARQL Protocol endpoint.

ATTRIBUTES

       The following attributes exist:

       "endpoint"
           A URL of the remote service implementing the SPARQL 1.1 Protocol. This value is a
           Attean::API::IRI, but can be coerced from a string.

       "silent"
       << user_agent >>
       "request_signer"

METHODS

       "query_request( $sparql )"
           Returns an HTTP::Request object for the given SPARQL query string.

       "query( $sparql )"
           Executes the given SPARQL query string at the remote endpoint. If execution is
           successful, returns an Attean::API::Iterator object with the results. If execution
           fails but the client "silent" flag is true, returns an empty iterator. Otherwise
           raises an error via "die".
