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"

30
31 "graph"
32 Returns the named graph.
33
34 "distinguish_bnode_variables"
35 Returns a new Path object with blank nodes replaced by

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
