6 RDF::Query::Algebra::NamedGraph - Algebra class for NamedGraph patterns
7
9 This document describes RDF::Query::Algebra::NamedGraph version 2.918.
10
12 Beyond the methods documented below, this class inherits methods from
13 the RDF::Query::Algebra class.
14
15 "new ( $graph, $pattern )"
16 Returns a new NamedGraph structure.
17
18 "construct_args"
19 Returns a list of arguments that, passed to this class'
20 constructor, will produce a clone of this algebra pattern.
21
22 "graph"
23 Returns the graph node of the named graph expression.
24
25 "pattern"
26 Returns the graph pattern of the named graph expression.
27
28 "quads"
29 Returns a list of the quads belonging to this NamedGraph.
30
31 "sse"
32 Returns the SSE string for this algebra expression.
33
34 "explain"
35 Returns a string serialization of the algebra appropriate for
36 display on the command line.
37
38 "as_sparql"
39 Returns the SPARQL string for this algebra expression.
40
41 "as_hash"
42 Returns the query as a nested set of plain data structures (no
43 objects).
44
45 "as_spin ( $model )"
46 Adds statements to the given model to represent this algebra object
47 in the SPARQL Inferencing Notation (<http://www.spinrdf.org/>).
48
49 "type"
50 Returns the type of this algebra expression.
51
52 "referenced_variables"
53 Returns a list of the variable names used in this algebra
54 expression.
55
56 "potentially_bound"
57 Returns a list of the variable names used in this algebra
58 expression that will bind values during execution.
59
60 "definite_variables"
61 Returns a list of the variable names that will be bound after
62 evaluating this algebra expression.
63
64 "qualify_uris ( \%namespaces, $base_uri )"
65 Returns a new algebra pattern where all referenced Resource nodes
66 representing QNames (ns:local) are qualified using the supplied
67 %namespaces.
68
69 "check_duplicate_blanks"
70 Returns true if blank nodes respect the SPARQL rule of no blank-
71 label re-use across BGPs, otherwise throws a
72 RDF::Query::Error::QueryPatternError exception.
