State Machine - UML Editor & Programmatic [message #468754] Tue, 23 January 2007 00:03 Go to next message
Eclipse UserFriend
Originally posted by: psentosa.yahoo.com

Hi,

I'd like to create a state machine both programmaticaly and by using the UML
editor, but I'm still confused on how to use them.

1. What are the differences between the usage of Packaged Element -,
Classifier Behaviour -, Nested Behaviour -, Owned Type-, and Do Actions
(Protocol) State Machine?
2. Can "State" exist only within "Region"? I read about "Region" only in the
context of concurrent region (thus, concurrent sub-state). But what about in
the non-concurrent environtment? Do we still need a region?
3. Is this the correct order to define a state charts:
- create (Owned Type/Packaged Element) State Machine
- Create Region
- Create State(s)
- ...??
4. Is there any way to define the beginning state/black circle? (Just like
we can define "Final State"/bordered circle)
5. To define sub states of, say, state A, do I have to create a region as a
child of State A, and then create some states within the newly created
region?

Programmaticaly, how can I create a state machine? If I use the factory
method UMLFactory.eInstance.createStateMachine and I'd like to put this
under the Model element, how can this be done?

Thanks and would appreciate any hints


Paul

Hi Paul,

UML can be a complicated puzzle ;) ... This is where a graphical tool comes
in handy.

Your best starting point is to look at the superstructure spec ..

A packageable element indicates a named element that may be owned directly
by a package.
Interfaces and classes can own nested classifiers ( ie nested classes ).
Packages can own "Types" ( ie. a class is a Type). Types are
PackageableElements.

Have a look at the UML superstructure spec for detailed explanations of all
these items ( I would simply be cutting and pasting definitions for these
items from the spec )

Yes in a non-concurent environment a statemachine would still own a region
in which you would have states.

Yes. ... a StateMachine is a Class. Packages own classess... The order
you have indicated is right.

Have a look at Pseudostates and the PseudostateKind enumeration. The
Pseudostate entry point is what you are interested in I believe.

Yes.

BehavioredClassifiers own behaviors ... StateMachine's are Behaviors.
You can use the BehavioredClassifier.createOwnedBehavior() or
myBehavioredClassifier.getOwnedBehaviors().add(UMLFactory.eI nstance.createStateMachine());

Hi James,

many thanks for your kind explanation.
To my last question....I'm sorry if I'm missing something, but somehow I
still can't relate my Model element to a BehavioredClassifier.
Is using myModel.createOwnedType() also an alternative? (By casting Type
into StateMachine). What kind of EClass argument should then be used?
Could you please explain a bit more?

Thanks again.

Paul

Hi Paul,

Ok ... let me back up a bit. Firstly, although Statemachines can be owned
direcly by a Package, by convention, they apply to a particular class.
So one would typically ( although not necessarily ) create a statemachine
under a class ( creating it directly under a Package is not wrong ).

So from your package you could do something like...


org.eclipse.uml2.uml.Class myClass =
(org.eclipse.uml2.uml.Class)myPackage.createOwnedType("myClass ",
ULPackage.Literals.CLASS);
// Note: Classes are Types
StateMachine myStateMachine =
(StateMachine)myClass.createOwnedBehavior("myStatemachine",
UMLPackage.Literals.STATE_MACHINE);
// Note: StateMachines are Behaviors, Behaviors are Classes.

Continue in this way to add a region and then a state etc.

The alternative is to manufacture these classes using the factory ie..
UMLFactory.eINSTANCE.createXXXX();
Then get the owning collection and add it in directly ( as mentioned
previously ).

Have a look at the "Getting started with UML" articles by Kenn Hussey for
better explanations.

Regards,

- James.

Thank you very much, James!

Best Regards
Paul

ps: Is it possible to have some more articles giving examples on how to use
the other APIs?

Hi Paul,

The migration document points out some of the new API's.
http://www.eclipse.org/modeling/mdt/uml2/docs/guides/UML2_2. 0_Migration_Guide/guide.html

You can add yourself to the notification list of this bugzilla to be the
first to get your hands on new articles.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=77413

Feel free to contribute articles yourself :)

Regards,

- James.

Hi Paul,

UML can be a complicated puzzle ;) ... This is where a graphical tool comes
in handy.

Your best starting point is to look at the superstructure spec ..

A packageable element indicates a named element that may be owned directly
by a package.
Interfaces and classes can own nested classifiers ( ie nested classes ).
Packages can own "Types" ( ie. a class is a Type). Types are
PackageableElements.

Have a look at the UML superstructure spec for detailed explanations of all
these items ( I would simply be cutting and pasting definitions for these
items from the spec )

Yes in a non-concurent environment a statemachine would still own a region
in which you would have states.

Yes. ... a StateMachine is a Class. Packages own classess... The order
you have indicated is right.

Have a look at Pseudostates and the PseudostateKind enumeration. The
Pseudostate entry point is what you are interested in I believe.

Yes.

BehavioredClassifiers own behaviors ... StateMachine's are Behaviors.
You can use the BehavioredClassifier.createOwnedBehavior() or
myBehavioredClassifier.getOwnedBehaviors().add(UMLFactory.eI nstance.createStateMachine());

Hi James,

many thanks for your kind explanation.
To my last question....I'm sorry if I'm missing something, but somehow I
still can't relate my Model element to a BehavioredClassifier.
Is using myModel.createOwnedType() also an alternative? (By casting Type
into StateMachine). What kind of EClass argument should then be used?
Could you please explain a bit more?

Thanks again.

Paul

Hi Paul,

Ok ... let me back up a bit. Firstly, although Statemachines can be owned
direcly by a Package, by convention, they apply to a particular class.
So one would typically ( although not necessarily ) create a statemachine
under a class ( creating it directly under a Package is not wrong ).

So from your package you could do something like...


org.eclipse.uml2.uml.Class myClass =
(org.eclipse.uml2.uml.Class)myPackage.createOwnedType("myClass ",
ULPackage.Literals.CLASS);
// Note: Classes are Types
StateMachine myStateMachine =
(StateMachine)myClass.createOwnedBehavior("myStatemachine",
UMLPackage.Literals.STATE_MACHINE);
// Note: StateMachines are Behaviors, Behaviors are Classes.

Continue in this way to add a region and then a state etc.

The alternative is to manufacture these classes using the factory ie..
UMLFactory.eINSTANCE.createXXXX();
Then get the owning collection and add it in directly ( as mentioned
previously ).

Have a look at the "Getting started with UML" articles by Kenn Hussey for
better explanations.

Regards,

- James.

Thank you very much, James!

ps: Is it possible to have some more articles giving examples on how to use
the other APIs?

Hi Paul,

The migration document points out some of the new API's.
http://www.eclipse.org/modeling/mdt/uml2/docs/guides/UML2_2. 0_Migration_Guide/guide.html

You can add yourself to the notification list of this bugzilla to be the
first to get your hands on new articles.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=77413

Feel free to contribute articles yourself :)

Regards,

- James.

I am doing what you were asking, and here is my code

StateMachine sm = UMLFactory.eINSTANCE.createStateMachine();
sm.setName(name);
sm.setPackage(behaviorModelPackage);
