NAME

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

VERSION

This document describes RDF::Query::Algebra::GroupGraphPattern version 2.918.

METHODS

Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class. "new ( @graph_patterns )" Returns a new GroupGraphPattern structure. "construct_args" Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern. "patterns" Returns a list of the graph patterns in this GGP. "add_pattern" Appends a new child pattern to the GGP. "quads" Returns a list of the quads belonging to this GGP. "sse" Returns the SSE string for this algebra expression. "explain" Returns a string serialization of the algebra appropriate for display on the command line. "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. "definite_variables" Returns a list of the variable names that will be bound after evaluating this algebra expression. "check_duplicate_blanks" Returns true if blank nodes respect the SPARQL rule of no blank-label re-use across BGPs, otherwise throws a RDF::Query::Error::QueryPatternError exception.
