StateProto is a .NET application that provides a design surface on which you can draw State Diagrams. If the diagram is sufficiently detailed, then it becomes possible to generate C# code to run against the QF4Net State Engine. Qf4net is a C#/.NET port by Dr. Rainer Hessmer of the Quantum Hierarchichal State Machine Framework by Miro Samek. Both of these frameworks are mainly the core State Machine execution engines. The advantage of the Quantum based frameworks is that they implement a Method-P... |
