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:
- "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.
