NAME

       Attean::SimpleQueryEvaluator - Simple query evaluator

VERSION

       This document describes Attean::SimpleQueryEvaluator version 0.012

SYNOPSIS

         use v5.14;
         use Attean;
         my $e = Attean::SimpleQueryEvaluator->new( model => $model );
         my $iter = $e->evaluate( $algebra, $active_graph );

DESCRIPTION

       The Attean::SimpleQueryEvaluator class implements a simple query evaluator that, given an
       Attean::API::Algebra and a Attean::API::Model object, evaluates the query represented by the algebra
       using data from the model, and returns a query result.

ATTRIBUTES

       "model"
           The Attean::API::Model object used for query evaluation.

       "default_graph"
           The Attean::API::IRI object representing the default graph in the "model".  The default graph will be
           excluded from enumeration of graph names for query features such as "GRAPH ?g {}".

METHODS

       "evaluate( $algebra, $active_graph )"
           Returns  an  Attean::API::Iterator  object  with  results  produced  by evaluating the query $algebra
           against the evaluator's "model", using the supplied $active_graph.
