RDF::Query::Algebra::Quad(3pm)				User Contributed Perl Documentation			    RDF::Query::Algebra::Quad(3pm)

NAME

       RDF::Query::Algebra::Quad - Algebra class for Quad patterns

VERSION

       This document describes RDF::Query::Algebra::Quad version 2.908.

METHODS

       Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.

       "new ( $s, $p, $o, $g )"
	   Returns a new Quad structure.

       "as_sparql"
	   Returns the SPARQL string for this algebra expression.

       "as_hash"
	   Returns the query as a nested set of plain data structures (no objects).

       "referenced_blanks"
	   Returns a list of the blank node names used in this algebra expression.

       "qualify_uris ( \%namespaces, $base_uri )"
	   Returns a new algebra pattern where all referenced Resource nodes representing QNames (ns:local) are qualified using the supplied
	   %namespaces.

       "bf ()"
	   Returns a string representing the state of the nodes of the triple (bound or free).

       "distinguish_bnode_variables"
	   Returns a new Quad object with blank nodes replaced by distinguished variables.

       "label ( $label => $value )"
	   Sets the named $label to $value for this quad object.  If no $value is given, returns the current label value, or undef if none exists.
