VERSION

10

METHODS

12       "new ( $s, $p, $o )"
13           Returns a new Triple structure.
14
15       "construct_args"
16           Returns a list of arguments that, passed to this class'
17           constructor, will produce a clone of this algebra pattern.
18
19       "nodes"
20           Returns the subject, predicate and object of the triple pattern.
21
22       "node_names"
23           Returns the method names for accessing the nodes of this statement.
24
25       "subject"
26           Returns the subject node of the triple pattern.
27
28       "predicate"
29           Returns the predicate node of the triple pattern.
30
31       "object"
32           Returns the object node of the triple pattern.
33
34       "as_string"
35           Returns the statement in a string form.
36
37       "has_blanks"
38           Returns true if any of the nodes in this statement are blank nodes.
39
40       "sse"
41           Returns the SSE string for this algebra expression.
42
43       "from_sse ( $string, $context )"
44           Parses the supplied SSE-encoded string and returns a
45           RDF::Trine::Statement object.
46
47       "type"
48           Returns the type of this algebra expression.
49
50       "referenced_variables"
51           Returns a list of the variable names used in this algebra
52           expression.
53
54       "definite_variables"
55           Returns a list of the variable names that will be bound after
56           evaluating this algebra expression.
57
58       "clone"
59       "bind_variables ( \%bound )"
60           Returns a new algebra pattern with variables named in %bound
61           replaced by their corresponding bound values.
62
63       "subsumes ( $statement )"
64           Returns true if this statement will subsume the $statement when
65           matched against a triple store.
66
67       "from_redland ( $statement )"
68           Given a RDF::Redland::Statement object, returns a perl-native
69           RDF::Trine::Statement object.
70
71       "rdf_compatible"
72           Returns true if and only if the statement can be expressed in RDF.
73           That is, the subject of the statement must be a resource or blank
74           node; the predicate must be a resource; and the object must be a
75           resource, blank node or literal.
76
77           RDF::Trine::Statement does allow statements to be created which
78           cannot be expressed in RDF - for instance, statements including
79           variables.
