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.
