# RDF::Query::Algebra::Path(3pm)

Algebra class for path patterns

## NAME

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

## VERSION

This document describes RDF::Query::Algebra::Path version 2.919.

## METHODS

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

- "new ( $start, \[ $op, @paths \], $end, $graph )"

  Returns a new Path structure.

- "construct\_args"

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

- "path"

  Returns the path description for this path expression.

- "start"

  Returns the path origin node.

- "end"

  Returns the path destination node.

- "graph"

  Returns the named graph.

- "distinguish\_bnode\_variables"

  Returns a new Path object with blank nodes replaced by distinguished variables.

- "bounded\_length"

  Returns true if the path is of bounded length.

- "sse"

  Returns the SSE string for this algebra expression.

- "as\_sparql"

  Returns the SPARQL string for this algebra expression.

- "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.
