"notes": "Starts a traversal starting from a given vertex and following. edges contained in a given edgeCollection. The request must contain the following attributes. <br><br>- <em>startVertex</em>: id of the startVertex, e.g. <em>\"users/foo\"</em>.<br><br>- <em>edgeCollection</em>: name of the collection that contains the edges.<br><br>- <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. <br><br>- <em>minDepth</em> (optional, ANDed with any existing filters): visits only nodes in at least the given depth <br><br>- <em>maxDepth</em> (optional, ANDed with any existing filters): visits only nodes in at most the given depth <br><br>- <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 <br><br>- <em>direction</em> (optional): direction for traversal - *if set*, must be either <em>\"outbound\"</em>, <em>\"inbound\"</em>, or <em>\"any\"</em> - *if not set*, the <em>expander</em> attribute must be specified <br><br>- <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 <br><br>- <em>expander</em> (optional): body (JavaScript) code of custom expander function *must* be set if <em>direction</em> attribute is *not* 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> <br><br>- <em>strategy</em> (optional): traversal strategy can be <em>\"depthfirst\"</em> or <em>\"breadthfirst\"</em> <br><br>- <em>order</em> (optional): traversal order can be <em>\"preorder\"</em> or <em>\"postorder\"</em> <br><br>- <em>itemOrder</em> (optional): item iteration order can be <em>\"forward\"</em> or <em>\"backward\"</em> <br><br>- <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> <br><br>- <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. <br><br><br><br>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>- <em>error</em>: boolean flag to indicate if an error occurred (<em>false</em> in this case) <br><br>- <em>code</em>: the HTTP status code<br><br>- <em>result</em>: the return value of the traversal<br><br>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>- <em>error</em>: boolean flag to indicate that an error occurred (<em>true</em> in this case)<br><br>- <em>code</em>: the HTTP status code<br><br>- <em>errorNum</em>: the server error number<br><br>- <em>errorMessage</em>: a descriptive error message<br><br>",
