NAME

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

VERSION

       This document describes RDF::Query::Algebra::Quad version 2.908.

METHODS

       Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.

       "new ( $s, $p, $o, $g )"
	   Returns a new Quad structure.

       "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).

       "referenced_blanks"
	   Returns a list of the blank node names used in 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.

       "bf ()"
	   Returns a string representing the state of the nodes of the triple (bound or free).

       "distinguish_bnode_variables"
	   Returns a new Quad object with blank nodes replaced by distinguished variables.

       "label ( $label => $value )"
	   Sets the named $label to $value for this quad object.  If no $value is given, returns the current label value, or undef if none exists.

NAME

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

VERSION

       This document describes RDF::Query::Algebra::Minus version 2.908.

METHODS

       Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.

       "new ( $pattern, $opt_pattern )"
	   Returns a new Minus structure.

       "construct_args"
	   Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.

       "pattern"
	   Returns the base pattern (LHS) onto which the minus pattern matches.

       "minus"
	   Returns the minus pattern (RHS).

       "sse"
	   Returns the SSE string for this algebra expression.

       "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).

       "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.
