Support for traversal of any depth

Reported by Andreas Ronge | December 28th, 2008 @ 08:50 PM | in 0.2.0

It now only support traversal of one level deep for has_one has has_many relationships Should be possible to specify how deep traversal The following should be easy to express in Neo4j.rb:

Traverser morpheusfriends = factory.createTraverser( Traverser.BREADTH_FIRST, // first return friends, then friends' friends morpheus, // start with Morpheus KNOWS, // relationship types we wish to traverse new DepthLimitStopEvaluator( 2 ), // don't traverse deeper than 2 levels ReturnableEvaluator.RETURN_ALL_BUT_START_NODE ); // return all nodes visited in

                                                // traversal except the first one

for ( Node friend : morpheusFriends )
