NAME

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

VERSION

       This document describes Attean::BindingEqualityTest version 0.033

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.
