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

VERSION
       This document describes RDF::Query::Algebra::BasicGraphPattern version 2.908.

METHODS
       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.

       "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.

       "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.
