The execution process may be optimized by not using visitors. Having instructions implement a method that returns a flow action directly.
| enum FlowAction { ACCEPT, REJ, DEFAULT } | FlowAction |
A FlowAction is what has to be done with the route. DEFAULT is the default action which is normally "go to the next term", or if the last term, ACCEPT.
| RuntimeError (class) | RuntimeError |
The semantic check should get rid of these.
