NAME

RDF::RDFa::Template::Unit - An individual graph pattern of an RDFa Template

SYNOPSIS

This class holds an individual graph pattern of an RDFa Template. This has several elements, a Basic Graph Pattern, a query endpoint and a graph name from the RDFa document.

$doc = RDF::RDFa::Template::Unit->new(triples => \@triples,
                                      endpoint => 'http://dbpedia.org/sparql',
                                      doc_graph => 'http://example.org/graph'

METHODS

new

The constructor. Takes three named arguments:

triples

An arrayref with RDF::Trine::Statements, or subclasses thereof.

endpoint

A SPARQL endpoint can optionally be set in the constructor.

doc_graph

A graph name for the document. TODO: Not used.

pattern

Will return an RDF::Query::Algebra::BasicGraphPattern object containing the Basic Graph Pattern of this unit.

endpoint

If no argument is given and the unit contains a SPARQL endpoint, this will be returned as a string. If a string argument is given, this will be used to set the endpoint URL.

results

Used to set and get a RDF::Trine::Iterator object that can be used to explore the query results for this unit.

To set the iterator, send a RDF::Trine::Iterator object as the only argument.

If no argument is given, this will return an RDF::Trine::Iterator object that can be used to explore the query results for this unit, or an empty hashref if no results are available.
