METHODS

Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class. "new ( $pattern, \@vars_and_exprs )" Returns a new Project structure. "construct_args" Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern. "pattern" Returns the pattern to be sorted. "vars" Returns the vars to be projected to. "sse" Returns the SSE string for this algebra expression. "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/>). "type" Returns the type of this algebra expression. "referenced_variables" Returns a list of the variable names used in this algebra expression. "bind_variables ( \%bound )" Returns a new algebra pattern with variables named in %bound replaced by their corresponding bound values. "potentially_bound" Returns a list of the variable names used in this algebra expression that will bind values during execution. "definite_variables" Returns a list of the variable names that will be bound after evaluating this algebra expression. "is_solution_modifier" Returns true if this node is a solution modifier.
