SYNOPSIS

13         use v5.14;
14         use Attean;
15         my $test      = Attean::BindingEqualityTest->new();
16         if ($test->equals($iter_a, $iter_b)) {
17           say "Iterators contain equivalent bindings";
18         }

DESCRIPTION

METHODS

24       "equals ( $graph1, $graph2 )"
25           Returns true if the invocant and $graph represent two equal RDF
26           graphs (e.g.  there exists a bijection between the RDF statements
27           of the invocant and $graph).
28
29       "is_subgraph_of ( $graph1, $graph2 )"
30           Returns true if the invocant is a subgraph of $graph. (i.e. there
31           exists an injection of RDF statements from the invocant to $graph.)
32
33       "injection_map ( $graph1, $graph2 )"
34           If the invocant is a subgraph of $graph, returns a mapping of blank
35           node identifiers from the invocant graph to $graph as a hashref.
36           Otherwise returns false. The solution is not always unique; where
37           there exist multiple solutions, the solution returned is arbitrary.
38
39       "split_blank_statements( $iter )"
40           Returns two array refs containing bindings from $iter, with
41           bindings containing blank nodes and bindings without any blank
42           nodes, respectively.
