RDF::Query::Algebra::BasicGraphPattern(3) User Contributed Perl Documentation RDF::Query::Algebra::BasicGraphPattern(3)

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

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

Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.
"new ( @triples )"
Returns a new BasicGraphPattern structure.
"construct_args"
Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
"triples"
Returns a list of triples belonging to this BGP.
"quads"
Returns a list of the (implicit) quads belonging to this BGP.
"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.
"connected"
Returns true if the pattern is connected through shared variables, false otherwise.
"subsumes ( $pattern )"
Returns true if the bgp subsumes the pattern, false otherwise.
"bf ()"
Returns a string representing the state of the nodes of the triple (bound or free).
"clone"
"bind_variables ( \%bound )"
Returns a new algebra pattern with variables named in %bound replaced by their corresponding bound values.
