AtteanX::Store::Memory - Simple in-memory RDF store
This document describes AtteanX::Store::Memory version 0.003_01
use AtteanX::Store::Memory;
AtteanX::Store::Memory provides an in-memory quad-store.
Beyond the methods documented below, this class inherits methods from the Attean::API::QuadStore class.
new ()
Returns a new memory-backed storage object.
size
Returns the number of quads in the store.
get_quads ( $subject, $predicate, $object, $graph )
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_graphs
Returns an iterator over the Attean::API::Term objects comprising the set of graphs of the stored quads.
add_quad ( $quad )
Adds the specified $quad to the underlying model.
$quad
remove_quad ( $statement )
Removes the specified $statement from the underlying model.
$statement
remove_quads ( $subject, $predicate, $object, $graph )
create_graph( $graph )
This is a no-op function for the memory quad-store.
drop_graph( $graph )
Removes all quads with the given $graph.
$graph
clear_graph( $graph )
count_quads ( $subject, $predicate, $object, $graph )
Returns a count of all the statements matching the specified subject, predicate, object, and graph. Any of the arguments may be undef to match any value.
etag_value_for_quads
If the store has the capability and knowledge to support caching, returns a persistent token that will remain consistent as long as the store's data doesn't change. This token is acceptable for use as an HTTP ETag.
