METHODS

12       Beyond the methods documented below, this class inherits methods from
13       the RDF::Query::Algebra class.
14
15       "new ( $start, [ $op, @paths ], $end, $graph )"
16           Returns a new Path structure.
17
18       "construct_args"
19           Returns a list of arguments that, passed to this class'
20           constructor, will produce a clone of this algebra pattern.
21
22       "path"
23           Returns the path description for this path expression.
24
25       "start"
26           Returns the path origin node.
27
28       "end"
29           Returns the path destination node.
30
31       "graph"
32           Returns the named graph.
33
34       "distinguish_bnode_variables"
35           Returns a new Path object with blank nodes replaced by
36           distinguished variables.
37
38       "bounded_length"
39           Returns true if the path is of bounded length.
40
41       "sse"
42           Returns the SSE string for this algebra expression.
43
44       "as_sparql"
45           Returns the SPARQL string for this algebra expression.
46
47       "type"
48           Returns the type of this algebra expression.
49
50       "referenced_variables"
51           Returns a list of the variable names used in this algebra
52           expression.
53
54       "potentially_bound"
55           Returns a list of the variable names used in this algebra
56           expression that will bind values during execution.
57
58       "definite_variables"
59           Returns a list of the variable names that will be bound after
60           evaluating this algebra expression.
