Metamorph: How to create the Hello World’s state Diagram in Enterprise Architect

In order to use a State Diagram modeled in Enterprise Architect you have to do following steps:

• Create a new Enterprise Architect project or open an existing one.
• Create two new packages called HelloWorld and Turnstile.

• The results should look like this (ignoring any other project packages):

• Right click Turnstile Package and click on add a new element.

• Choose the StateMachine type from the drop down list.

• Write Turnstile in the name field and click Ok.

• Double click on the Turnstile StateMachine Diagram:

• Add an Initial State from the toolbox.

• Add a state from the toolbox and type Locked in the name field.

• Add the Unlocked state by following the same step as above, the results should look like this:

• Add the transitions as shown in the following diagram:

• Double click on the transition that goes from Locked to Unlocked and type “coin” in the Link name field.

• Do the same for the other transitions as shown in the following diagram:

• Double click on the transition called coin and type Metamorph.Examples.HelloWorld.UnlockCondition in the guard field and Metamorph.Examples.HelloWorld.UnlockAction in the effect field.

• Do the same for the following transitions:

Source	Target	Transition	Action
Locked	Locked	pass	Metamorph.Examples.HelloWorld.SoundAlarmAction
Unlocked	Locked	pass	Metamorph.Examples.HelloWorld.LockAction
Unlocked	Unlocked	coin	SendMessageAction

The results should look like this:

• Select the Turnstile Package created earlier and click on the Export package to XMI file menu item

• Type the file name and folder in the Filename field. The dialog box should look like this:

Click on the Export button.

• Finally we need to convert the StateMachine.xmi to a format that Metamorph undestands. In order to do this one final step is required.
  • Find the Uml2Xml Converter console application located in the Metamorph distribution under Support Tools.
  • Execute the following command line: Uml2XmlConverter C:\ StateMachine.xmi StateMachine.xml

OK. We are good to go :D
