Class Method Details

.orient(url = nil, args = nil) ⇒ Object

Return a graph for the given path. Will create a graph if none exists at that location.

If the graph is opened from a path, it will be registered to be closed by Ruby’s at_exit callback, but if an already open graph is given, it will not.
