METHODS

18       Beyond the methods documented below, this class inherits methods from
19       the RDF::Trine::Model class.
20
21       "new ( $model )"
22           Returns a new dataset-model over the supplied model.
23
24       "push_dataset ( default => \@graphs, named => \@graphs )"
25           Creates a new dataset view over the underlying model.
26
27       "pop_dataset"
28           Removes the last pushed dataset view.
29
30       "temporary_model"
31           Returns a new temporary (non-persistent) model.
32
33       "add_hashref ( $hashref [, $context] )"
34           Add triples represented in an RDF/JSON-like manner to the model.
35
36       "size"
37           Returns the number of statements in the model.
38
39       "supports ( [ $feature ] )"
40           If $feature is specified, returns true if the feature is supported
41           by the underlying store, false otherwise. If $feature is not
42           specified, returns a list of supported features.
43
44       "count_statements ( $subject, $predicate, $object )"
45           Returns a count of all the statements matching the specified
46           subject, predicate and objects. Any of the arguments may be undef
47           to match any value.
48
49       "add_statement ( $statement [, $context] )"
50           Adds the specified $statement to the rdf store.
51
52       "remove_statement ( $statement [, $context])"
53           Removes the specified $statement from the rdf store.
54
55       "remove_statements ( $subject, $predicate, $object [, $context] )"
56           Removes all statements matching the supplied $statement pattern
57           from the rdf store.
58
59       "get_statements ($subject, $predicate, $object [, $context] )"
60           Returns an iterator of all statements matching the specified
61           subject, predicate and objects from the rdf store. Any of the
62           arguments may be undef to match any value.
63
64           If three or fewer arguments are given, the statements returned will
65           be matched based on triple semantics (the graph union of triples
66           from all the named graphs). If four arguments are given (even if
67           $context is undef), statements will be matched based on quad
68           semantics (the union of all quads in the underlying store).
69
70       "get_pattern ( $bgp [, $context] [, %args ] )"
71           Returns a stream object of all bindings matching the specified
72           graph pattern.
73
74       "get_sparql ( $sparql )"
75           Returns a stream object of all bindings matching the specified
76           graph pattern.
77
78       "get_graphs"
79       "get_contexts"
80           Returns an iterator containing the nodes representing the named
81           graphs in the model.
82
83       "model"
84           Returns the underlying model object.
