NAME
RDF::Query::Algebra::NamedGraph - Algebra class for NamedGraph patterns
VERSION
This document describes RDF::Query::Algebra::NamedGraph version 2.907.
METHODS
Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.
new ( $graph, $pattern )-
Returns a new NamedGraph structure.
construct_args-
Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
graph-
Returns the graph node of the named graph expression.
pattern-
Returns the graph pattern of the named graph expression.
quads-
Returns a list of the quads belonging to this NamedGraph.
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.
qualify_uris ( \%namespaces, $base_uri )-
Returns a new algebra pattern where all referenced Resource nodes representing QNames (ns:local) are qualified using the supplied %namespaces.
