Generation
SDE-VS can assist you in drawing a State Machine Diagram, as well as generate a State Machine Diagram Code.

Drawing State Machine Diagram
To generate a state machine diagram, you should first have a Class on the class diagram. Select Sub Diagrams > State
Machine Diagram > Create State Machine Diagram from the pop-down menu of the class to create a sub diagram.
Figure 12.2 - Select Create State Machine Diagram

SDE-VS User’s Guide (Part 1) Chapter 12 – State Machine Diagram Code Generation
You will see an initial pseudo state on the state machine diagram.
Figure 12.3 - State machine diagram with an initial
pseudo state
Drag a State from the diagram toolbar and drop the diagram.
Figure 12.4 - Drag and drop a State
Alternatively, you can use the resources of the initial pseudo state.
A diagram can then be created.

Generate State Machine Code
The process of creating a State Machine Code is simple.
To generate a state machine code:
1. Select Modeling > State Machine Code >Generate Code... from the main menu.
12-4
Figure 12.7 - Select Generate Code...
2. The Generate state machine code dialog is displayed.
Figure 12.8 - Generate state machine code dialog
3. Select a language to generate the code in from the drop-down menu.

4.Configure the Output Path. The default output directory is the directory of Visual Studio. You may change the output
directory by deselecting the "Generate to Source Folder" item.

Programming with Generated State Machine Code
SDE-VS supports the generation of different types of state machine code. Since the steps for generation of codes in different
languages are similar, Java will be used as an example to illustrate the steps.
Before generating the code, you may want to configure the properties of states and transitions.
For state, configure by selecting Open Specification...from the pop-up menu.
12-6
Figure 12.13 - Select Open Specification...
The State Specification dialog box is now open, and you can configure the state properties here. You may edit the Entry
property by clicking Edit... .
Figure 12.14 - State Specification dialog box

SDE-VS User’s Guide (Part 1) Chapter 12 – State Machine Diagram Code Generation
This is the Activity Specification(Entry) dialog box. After editing to suit your needs, click OK to confirm.

Similarly, you can edit the transition by selecting the Open Specification... from the pop-up menu.
12-8
Figure 12.17 - Open Specification...
Then, edit the properties of transition in the Transition Specification dialog box.

Reverse State Machine Code
Apart from generation of state machine code, SDE-VS also supports the reversal of the state machine code file, with
extension .sm.

SDE-VS User’s Guide (Part 1) Chapter 12 – State Machine Diagram Code Generation
To reverse the .sm file:
1. Select Modeling > State Machine Code > Reverse Code... from the main menu .
12-10
Figure 12.27 - Select Reverse Code...
2. The Reverse State Machine Code dialog box is displayed. Select the Class and State Diagram.
Figure 12.28 - Reverse State Machine Code
dialog box
3. Configure the input file path by typing in the text box or select ... .Select OK to confirm.
Figure 12.29 - Configure the input file path
4. The progress of reversal is shown. You can select to Close Dialog when finished progress by checking the check box.
