The GRAPH_VERTICES function returns all vertices.

GRAPH_VERTICES (graphName, vertexExample, options)

According to the optional filters it will only return vertices that have outbound, inbound or any (default) edges.

Parameters

• graphName : The name of the graph as a string.
• vertexExample : An example for the desired vertices (see example).
• options (optional) : An object containing the following options:
  • direction : The direction of the edges as a string. Possible values are outbound, inbound and any (default).
  • vertexCollectionRestriction : One or multiple vertex collections that should be considered.
