| ---++ Description |
| Get a list of adjacent vertices or edges with a direction. |
| |
| ---++ Parameters |
| * :id is the id of the vertex. |
| * :direction is the direction associated with the edges. |
| |
| To get the adjacent out vertices of vertex pass direction as out, in to get adjacent in vertices |
| and both to get both in and out adjacent vertices. Similarly to get the out edges of vertex |
| pass outE, inE to get in edges and bothE to get the both in and out edges of vertex. |
| |
| * out : get the adjacent out vertices of vertex |
| * in : get the adjacent in vertices of vertex |
| * both : get the both adjacent in and out vertices of vertex |
| * outCount : get the number of out vertices of vertex |
| * inCount : get the number of in vertices of vertex |
| * bothCount : get the number of adjacent in and out vertices of vertex |
| * outIds : get the identifiers of out vertices of vertex |
| * inIds : get the identifiers of in vertices of vertex |
| * bothIds : get the identifiers of adjacent in and out vertices of vertex |
| |
| ---++ Results |
| Adjacent vertices of the vertex for the specified direction. |
