The request must contain the following attributes. <br><br>  <ul class=\"swagger-list\"><li><em>startVertex</em>: id of the startVertex, e.g. <em>\"users/foo\"</em>.  <li><em>edgeCollection</em>: (optional) name of the collection that contains the edges.  <li><em>graphName</em>: (optional) name of the graph that contains the edges.   Either <em>edgeCollection</em> or <em>graphName</em> has to be given.   In case both values are set the <em>graphName</em> is prefered.  <li><em>filter</em> (optional, default is to include all nodes):   body (JavaScript code) of custom filter function   function signature: (config, vertex, path) -> mixed   can return four different string values:   - <em>\"exclude\"</em> -> this vertex will not be visited.   - <em>\"prune\"</em> -> the edges of this vertex will not be followed.   - <em>\"\"</em> or <em>undefined</em> -> visit the vertex and follow it's edges.   - <em>Array</em> -> containing any combination of the above.     If there is at least one <em>\"exclude\"</em> or <em>\"prune\"</em> respectivly     is contained, it's effect will occur.  <li><em>minDepth</em> (optional, ANDed with any existing filters):   visits only nodes in at least the given depth  <li><em>maxDepth</em> (optional, ANDed with any existing filters):   visits only nodes in at most the given depth  <li><em>visitor</em> (optional): body (JavaScript) code of custom visitor function   function signature: (config, result, vertex, path) -> void   visitor function can do anything, but its return value is ignored. To   populate a result, use the <em>result</em> variable by reference  <li><em>direction</em> (optional): direction for traversal - <em>if set</em>, must be either <em>\"outbound\"</em>, <em>\"inbound\"</em>, or <em>\"any\"</em> - <em>if not set</em>, the <em>expander</em> attribute must be specified  <li><em>init</em> (optional): body (JavaScript) code of custom result initialisation function   function signature: (config, result) -> void   initialise any values in result with what is required  <li><em>expander</em> (optional): body (JavaScript) code of custom expander function    <em>must</em> be set if <em>direction</em> attribute is <em>not</em> set    function signature: (config, vertex, path) -> array    expander must return an array of the connections for <em>vertex</em>    each connection is an object with the attributes <em>edge</em> and <em>vertex</em> <li><em>sort</em> (optional): body (JavaScript) code of a custom comparison function    for the edges. The signature of this function is    (l, r) -> integer (where l and r are edges) and must    return -1 if l is smaller than, +1 if l is greater than,    and 0 if l and r are equal. The reason for this is the    following: The order of edges returned for a certain    vertex is undefined. This is because there is no natural    order of edges for a vertex with multiple connected edges.    To explicitly define the order in which edges on the    vertex are followed, you can specify an edge comparator    function with this attribute. Note that the value here has    to be a string to conform to the JSON standard, which in    turn is parsed as function body on the server side. Furthermore    note that this attribute is only used for the standard    expanders. If you use your custom expander you have to    do the sorting yourself within the expander code.  <li><em>strategy</em> (optional): traversal strategy    can be <em>\"depthfirst\"</em> or <em>\"breadthfirst\"</em>  <li><em>order</em> (optional): traversal order    can be <em>\"preorder\"</em> or <em>\"postorder\"</em>  <li><em>itemOrder</em> (optional): item iteration order   can be <em>\"forward\"</em> or <em>\"backward\"</em>  <li><em>uniqueness</em> (optional): specifies uniqueness for vertices and edges visited    if set, must be an object like this:    <em>\"uniqueness\": {\"vertices\": \"none\"|\"global\"|path\", \"edges\": \"none\"|\"global\"|\"path\"}</em>  <li><em>maxIterations</em> (optional): Maximum number of iterations in each traversal. This number can be  set to prevent endless loops in traversal of cyclic graphs. When a traversal performs  as many iterations as the <em>maxIterations</em> value, the traversal will abort with an  error. If <em>maxIterations</em> is not set, a server-defined value may be used.   </ul> If the Traversal is successfully executed <em>HTTP 200</em> will be returned. Additionally the <em>result</em> object will be returned by the traversal. <br><br> For successful traversals, the returned JSON object has the following properties: <br><br>  <ul class=\"swagger-list\"><li><em>error</em>: boolean flag to indicate if an error occurred (<em>false</em> in this case)  <li><em>code</em>: the HTTP status code  <li><em>result</em>: the return value of the traversal  </ul> If the traversal specification is either missing or malformed, the server will respond with <em>HTTP 400</em>. <br><br> The body of the response will then contain a JSON object with additional error details. The object has the following attributes: <br><br>  <ul class=\"swagger-list\"><li><em>error</em>: boolean flag to indicate that an error occurred (<em>true</em> in this case)  <li><em>code</em>: the HTTP status code  <li><em>errorNum</em>: the server error number  <li><em>errorMessage</em>: a descriptive error message",
