RDF::Query::Algebra::Path - Algebra class for path patterns

This document describes RDF::Query::Algebra::Path version 2.200, released 6 August 2009.

new ( $start,
[ $op,
@paths ],
$end )Returns a new Path structure.
construct_argsReturns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
pathReturns the path description for this path expression.
startReturns the path origin node.
endReturns the path destination node.
sseReturns the SSE string for this alegbra expression.
as_sparqlReturns the SPARQL string for this alegbra expression.
typeReturns the type of this algebra expression.
referenced_variablesReturns a list of the variable names used in this algebra expression.
definite_variablesReturns a list of the variable names that will be bound after evaluating this algebra expression.
fixup ( $query,
$bridge,
$base,
\%namespaces )Returns a new pattern that is ready for execution using the given bridge. This method replaces generic node objects with bridge-native objects.
execute ( $query,
$bridge,
\%bound,
$context,
%args )
match_path ( $query,
$bridge,
\%bound,
$context,
$current_node,
