-
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.
