Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.
"new ( $s, $p, $o )"
Returns a new Triple structure.
Returns the SPARQL string for this algebra expression.

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