Path Pipe

PathPipe allows clients to understand how traversal algorithm reached given node. It takes as a source any type of BasePipe child, and emits array of objects (vertices, edges, etc.) through which it went to reach final point

Example of traversal for Graph of Gods:

  g.V('hercules')  // get 'hercules' vertex
   .out('father')  // Who is father of Hercules?
   .out('brother') // Get all Hercules uncles
   .out('pet')     // Get pets of Hercules uncles.
   .path()         // Get traversal path
   .forEach(function (path) {
     // path is array of vertices
     // [hercules] -> [father] -> [brother] -> [pet]
     console.log(path);
   });
