RDF::Query::Algebra::Path - Algebra class for path patterns
VERSION
This document describes RDF::Query::Algebra::Path version 2.908.
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.

Hi All,
I am trying to find a particular string in a path, but able to do so.
I tried through grep command but its taking so long time which is not appropriate.
e.g:
Path : /oct/oracle/apps/OMEC/appl/xxaterp/1.0/reports/US/
Suppose in this path we have 10 .rdf file and I want to... (2 Replies)
