15
17 The Attean::QuadModel class represents a model that is backed by a
18 single Attean::API::QuadStore object. It conforms to the
19 Attean::API::Model role.
20
21 The Attean::QuadModel constructor requires one named argument:
22
23 store
24 A Attean::API::QuadStore object representing the backing quad-
25 store.
26
28 "get_quads ( $subject, $predicate, $object, $graph )"
29 Returns an Attean::API::Iterator for quads in the model that match
30 the supplied $subject, $predicate, $object, and $graph. Any of
31 these terms may be undefined or a Attean::API::Variable object, in
32 which case that term will be considered as a wildcard for the
33 purposes of matching.
34
35 The returned iterator conforms to both Attean::API::Iterator and
36 Attean::API::QuadIterator.
37
38 "plans_for_algebra( $algebra, $model, $active_graphs, $default_graphs
39 )"
40 Delegates to the underlying store if the store consumes
41 Attean::API::CostPlanner.
42
43 "cost_for_plan( $plan )"
44 Delegates to the underlying store if the store consumes
45 Attean::API::CostPlanner.
