NAME
RDF::Query::Algebra::NamedGraph - Algebra class for NamedGraph patterns
VERSION
This document describes RDF::Query::Algebra::NamedGraph version 2.908.
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 )"
