RDF::Core::Evaluator - gets a query object that RDF::Core::Query parsed and evaluates the query.
my %namespaces = (Default => 'http://myApp.gingerall.org/ns#', ns => 'http://myApp.gingerall.org/ns#', ); my $evaluator = new RDF::Core::Evaluator (Model => $model, #an instance of RDF::Core::Model Factory => $factory, #an instance of RDF::Core::NodeFactory Namespaces => \%namespaces, ); my $query = new RDF::Core::Query(Evaluator=> $evaluator);
The evaluator is just to be created and passed to query object, that uses it to evaluate the query.
Available options are:
RDF::Core::Model object that contains data to be queried.
RDF::Core::Function object is a functions library.
RDF::Core::NodeFactory object, that produces resource and literal objects.
A hash containing namespace prefixes as keys and URIs as values. See more in paragraph Names and URIs in RDF::Core::Query,
A code reference that is called every time a result row is found. The row elements are passed as parameters of the call. They can be undefined, RDF::Core::Resource or RDF::Core::Literal value. If Row is omitted, result is returned as a reference to array of rows
