biz.dfch.CS.StateMachine

A simple C# based State Machine that can be configured via State Transitions based on an idea by Juliet "Simple state machine example in C#?"

You can download this package via NuGet with Install-Package biz.dfch.CS.StateMachine.

DESCRIPTION

The project contains an extendable StateMachine that defines a few simple states and two conditions ("Continue", "Cancel") that can be used to advance (transition) through that state machine.

When instatiating the StateMachine with the default constructor the following states, conditions and transitions will be set up per default

States

• Running
• InternalErrorState
• Completed
• Cancelled
• Disposed

Conditions

• Continue
• Cancel

Transitions

Source state	Condition	Target state
InitialState	Continue	Running
InitialState	Cancel	InternalErrorState
Running	Continue	Completed
Running	Cancel	Cancelled
Completed	Continue	Disposed
Completed	Cancel	InternalErrorState
Cancelled	Continue	Disposed
Cancelled	Cancel	InternalErrorState
InternalErrorState	Continue	Disposed

Basic functionalities

1. The Continue condition makes a transition from an arbitrary state to the next state as the "good case"
2. The Cancel condition makes a transition from an arbitrary state to the next state as the "bad case"
3. Furthermore there is the GetNext method to transit to the next state based on a given condition.

There are as well methods for exporting and importing the configuration along with the states:

• GetStringRepresentation()
• SetupStateMachine(String configuration, String currentState = null, String previousState = null)
