.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
RDF::Trine::Store::SPARQL provides a RDF::Trine::Store \s-1API\s0 to interact with a
remote \s-1SPARQL\s0 endpoint.
.SH "METHODS"
.IX Header "METHODS"
Beyond the methods documented below, this class inherits methods from the
RDF::Trine::Store class.
.ie n .IP """new ( $url )""" 4
.el .IP "\f(CWnew ( $url )\fR" 4
.IX Item "new ( $url )"
Returns a new storage object that will act as a proxy for the \s-1SPARQL\s0 endpoint
accessible via the supplied \f(CW$url\fR.
.ie n .IP """new_with_config ( $hashref )""" 4
.el .IP "\f(CWnew_with_config ( $hashref )\fR" 4
.IX Item "new_with_config ( $hashref )"
Returns a new storage object configured with a hashref with certain
keys as arguments.
.Sp
The \f(CW\*(C`storetype\*(C'\fR key must be \f(CW\*(C`SPARQL\*(C'\fR for this backend.
.Sp
The following key must also be used:
.RS 4
.ie n .IP """url""" 4
.el .IP "\f(CWurl\fR" 4
.IX Item "url"
The \s-1URL\s0 of the remote endpoint.

.ie n .IP """new_with_config ( \e%config )""" 4
.el .IP "\f(CWnew_with_config ( \e%config )\fR" 4
.IX Item "new_with_config ( %config )"
Returns a new RDF::Trine::Store object based on the supplied configuration hashref.
.ie n .IP """get_statements ( $subject, $predicate, $object [, $context] )""" 4
.el .IP "\f(CWget_statements ( $subject, $predicate, $object [, $context] )\fR" 4
.IX Item "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.
.ie n .IP """get_pattern ( $bgp [, $context] )""" 4
.el .IP "\f(CWget_pattern ( $bgp [, $context] )\fR" 4
.IX Item "get_pattern ( $bgp [, $context] )"
Returns an iterator object of all bindings matching the specified graph pattern.
.ie n .IP """get_contexts""" 4
.el .IP "\f(CWget_contexts\fR" 4
.IX Item "get_contexts"
Returns an RDF::Trine::Iterator over the RDF::Trine::Node objects comprising
the set of contexts of the stored quads.

.el .IP "\f(CWcount_statements ( $subject, $predicate, $object, $context )\fR" 4
.IX Item "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.

Returns the number of statements in the store.
.ie n .IP """supports ( [ $feature ] )""" 4
.el .IP "\f(CWsupports ( [ $feature ] )\fR" 4
.IX Item "supports ( [ $feature ] )"
If \f(CW$feature\fR is specified, returns true if the feature is supported by the
store, false otherwise. If \f(CW$feature\fR is not specified, returns a list of
supported features.
