Hello Mercelo,
I know this might be little teasing but i am very new to EMF paradigm. I
went through the tutorial referance u gave to me but as far as i
understood from that, it shows that EMF supports the UML constructs in
ECORE format only for class diagram ( slides 33, 34, 35) and there is no
supprt for state machine or activity diagrams. Thats why I again posted my
question making it little more clear that i want to work with activity
diagrams and State diagrams and not class diagrams.
I have also Tried to convert my state diagrams into ecore format by using
UML plugin but it also gives the empty state machine class. THough it
works fine with class diagram in uml format.
It might be little stupid question but i am very new to this field so i
apologise if i made u feel annoyed.
Great work though
Thanks a lot
Hemant

Hi Hemant,
I was not really annoyed (perhaps just a little ;-) ). Another tip is
to keep the same discussion in one single thread. Rest assured that we
will not miss it ;-)
The pages you mention show to someone that understands UML what Ecore
is: in very simple terms, it is a model that can represent the things
you have in class diagrams.
That said, lets think about what is the UML2 project. From its page, it
is "an EMF-based implementation of the Unified Modeling Language (UMLTM)
2.x OMG metamodel". In the UML2 project, "things" like Class, Activity,
State, and others are EMF classes (hence the "EMF-based
implementation"). So, dealing with a bunch of instances of UML2 (like a
state machine defined in a resource/diagram) is the same as dealing with
any other "bunch of instances" from a EMF model, like the "Library"
model we use on our tutorials (again see our documentation page). In
other words, you can use a simpler model to understand EMF and then use
that knowledge to tackle more complicated models.
Anyway, I did a quick scan on the UML2 newsgroup
(eclipse.modeling.mdt.uml2). The following posts may help you (the
first one, in particular):
"State Machine - UML Editor & Programmatic" from 1/22/2007 7:03 PM
"Ecore for Sequence diagram" from 3/1/2007 4:35 PM
"how to find out the type of element in a package" from 2/10/2008 5:38 AM
"UML2 / Sequence diagram / MessageKind" from 12/2/2007 6:03 AM
"Programmetic Create Connetor between Port" from 2/26/2007 4:51 AM
"Sequence Diagrams" from 5/1/2007 2:57 PM
You could ask in the UML2 newsgroup if someone has a code that reads a
state machine. You may be lucky ;-)
Cheers,
Marcelo
