RDF::Query::Algebra::BasicGraphPattern - Algebra class for BasicGraphPattern patterns
This document describes RDF::Query::Algebra::BasicGraphPattern version 2.909.
Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.
new ( @triples )
Returns a new BasicGraphPattern structure.
Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
Returns a list of triples belonging to this BGP.
Returns a list of the (implicit) quads belonging to this BGP.
Returns the SSE string for this algebra expression.
Returns a string serialization of the algebra appropriate for display on the command line.
Returns the SPARQL string for this algebra expression.
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/).
Returns the type of this algebra expression.
Returns a list of the variable names used in this algebra expression.
Returns a list of the variable names used in this algebra expression that will bind values during execution.
Returns a list of the variable names that will be bound after evaluating this algebra expression.
Returns true if the pattern is connected through shared variables, false otherwise.
subsumes ( $pattern )
Returns true if the bgp subsumes the pattern, false otherwise.
Returns a string representing the state of the nodes of the triple (bound or free).
bind_variables ( \%bound )
Returns a new algebra pattern with variables named in %bound replaced by their corresponding bound values.
