NAME¶
Attean::SimpleQueryEvaluator - Simple query evaluator
VERSION¶
This document describes Attean::SimpleQueryEvaluator version 0.002
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.
