NAME

       Attean::BindingEqualityTest - Test for equality of binding sets with bnode isomorphism

VERSION

       This document describes Attean::BindingEqualityTest version 0.019

SYNOPSIS

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

DESCRIPTION

       ...

METHODS

       "equals ( $graph1, $graph2 )"
           Returns true if the invocant and $graph represent two equal RDF graphs (e.g.  there
           exists a bijection between the RDF statements of the invocant and $graph).

       "is_subgraph_of ( $graph1, $graph2 )"
           Returns true if the invocant is a subgraph of $graph. (i.e. there exists an injection
           of RDF statements from the invocant to $graph.)

       "injection_map ( $graph1, $graph2 )"
           If the invocant is a subgraph of $graph, returns a mapping of blank node identifiers
           from the invocant graph to $graph as a hashref. Otherwise returns false. The solution
           is not always unique; where there exist multiple solutions, the solution returned is
           arbitrary.

       "split_blank_statements( $iter )"
           Returns two array refs containing bindings from $iter, with bindings containing blank
           nodes and bindings without any blank nodes, respectively.
