NAME

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

VERSION

       This document describes RDF::Query::Algebra::Triple version 2.910.

METHODS

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

       "new ( $s, $p, $o )"
           Returns a new Triple 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).

       "as_spin ( $model )"
           Adds statements to the given model to represent this algebra object in the SPARQL
           Inferencing Notation (<http://www.spinrdf.org/>).

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

       "subsumes ( $pattern )"
           Returns true if the triple subsumes the pattern, false otherwise.

       "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 triple object.  If no $value is given,
           returns the current label value, or undef if none exists.
