"pattern" Returns the filter pattern. "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. "potentially_bound" Returns a list of the variable names used in this algebra expression that will bind values during execution.
