A self-writing traversal.

[Marko Rodriguez]

Hello,

Assume the following graph.

g = TinkerGraph.open().traversal()

g.addV().property(id,1).property('op','g.').as('g.').

  addV().property('op','V(1).').as('V(1).').

  addV().property('op','repeat(').as('repeat(').

  addV().property('op','out()).').as('out()).').

  addV().property('op','times(4).').

         property('name',"x",'op',"properties('name')").as('times(4).').

  addE('link').from('g.').to('V(1).').

  addE('link').from('V(1).').to('repeat(').

  addE('link').from('repeat(').to('out()).').

  addE('link').from('out()).').to('times(4).')

Next, assume the following traversal:

g.V(1).repeat(out()).times(4).properties('name')

Look at the path that is traversed when the above traversal is executed against the above graph.

gremlin> g.V(1).repeat(out()).times(4).properties('name').path().by('op')

==>[g.,V(1).,repeat(,out()).,times(4).,properties('name')]

This is a traversal that writes itself out.

So whats up Kuppitz? You just going to let me throw down a wicked nasty and not come back with something even better?!

Ha, nope. I've tried to tweak it a bit, but ended up with something that was no longer a self-writing traversal.

Cheers,

Daniel
