"notes": "Starts a traversal starting from a given vertex and following. edges contained in a given edgeCollection. The request must contain the following attributes.
- startVertex: id of the startVertex, e.g. \"users/foo\".
- edgeCollection: name of the collection that contains the edges.
- filter (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: - \"exclude\" -> this vertex will not be visited. - \"prune\" -> the edges of this vertex will not be followed. - \"\" or undefined -> visit the vertex and follow it's edges. - Array -> containing any combination of the above. If there is at least one \"exclude\" or \"prune\" respectivly is contained, it's effect will occur. - minDepth (optional, ANDed with any existing filters): visits only nodes in at least the given depth - maxDepth (optional, ANDed with any existing filters): visits only nodes in at most the given depth - visitor (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 result variable by reference - direction (optional): direction for traversal - *if set*, must be either \"outbound\", \"inbound\", or \"any\" - *if not set*, the expander attribute must be specified - init (optional): body (JavaScript) code of custom result initialisation function function signature: (config, result) -> void initialise any values in result with what is required - expander (optional): body (JavaScript) code of custom expander function *must* be set if direction attribute is *not* set function signature: (config, vertex, path) -> array expander must return an array of the connections for vertex each connection is an object with the attributes edge and vertex - strategy (optional): traversal strategy can be \"depthfirst\" or \"breadthfirst\" - order (optional): traversal order can be \"preorder\" or \"postorder\" - itemOrder (optional): item iteration order can be \"forward\" or \"backward\" - uniqueness (optional): specifies uniqueness for vertices and edges visited if set, must be an object like this: \"uniqueness\": {\"vertices\": \"none\"|\"global\"|path\", \"edges\": \"none\"|\"global\"|\"path\"} - maxIterations (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 maxIterations value, the traversal will abort with an error. If maxIterations is not set, a server-defined value may be used.
If the Traversal is successfully executed HTTP 200 will be returned. Additionally the result object will be returned by the traversal.
For successful traversals, the returned JSON object has the following properties:
- error: boolean flag to indicate if an error occurred (false in this case)
- code: the HTTP status code
- result: the return value of the traversal
If the traversal specification is either missing or malformed, the server will respond with HTTP 400.
The body of the response will then contain a JSON object with additional error details. The object has the following attributes:
- error: boolean flag to indicate that an error occurred (true in this case)
- code: the HTTP status code
- errorNum: the server error number
- errorMessage: a descriptive error message
