NAME

       RDF::Helper::RDFReland::Query - Perlish convenience extension for RDF::Redland::Query

SYNOPSIS

	 my $model = RDF::Redland::Model->new(
	     RDF::Redland::Storage->new( %storage_options )
	 );

	 my $rdf = RDF::Helper->new(
	   Namespaces => \%namespaces,
	   BaseURI => 'http://domain/NS/2004/09/03-url#'
	 );

	 my $q_obj = $rdf->new_query( $sparql_text, 'sparql' );

	 # arrays
	 while ( my $row = $q_obj->selectrow_arrayref ) {
	     # $row is an array reference.
	 }

	 # hashes
	 while ( my $row = $q_obj->selectrow_hashref ) {
	     # $row is a hash reference.
	 }

DESCRIPTION

       RDF::Helper::RDFRedland::Query is the object retuned from RDF::Helper's new_query() method when using RDF::Redland as the base interface
       class. This object provides everything that an instance of RDF::Redland::Query offers, plus the convenience methods  detailed below.

METHODS

   selectrow_arrayref
       Returns each row as a Perl array references. The order of the array's indices will correspond to the order of the variable bindings in the
       query.

   selectrow_hashref
       Returns each row as a Perl hash references. The keys in the hash will have the same names as the variable bindings in the query.
