Hi all,
I am new in GMF, I generated a diagram which is working fine. along with
diagram the gmf generated an other editor that writes the description of
model elements immediately when I click save button after drawing elements
on diagram.
I want to create a new editor similar to the editor along with diagram for
description of model elements(but as an xml file). I explored diagram.part
(package)but it looks little complex.
I will be greatfull if some one can give me idea how can I solve this
problem.
Thanks in advance

It seems to me that GMF fully supports storing the model in a separate
file from the diagram description for how it's displayed graphically. I
don't know enough details to explain specifically what's needed but in
general the idea would be that you'd have two separate resources. One
for the diagram and one for the model. Just as the example Ecore editor
stores a .ecore file and a .ecore_diagram file. When you save after
making changes, both these files would be changed. Maybe there's even a
generation option for separating the diagram from the model instance, I
don't know, but it's certainly achievable and I suppose you could look
at the example ecore diagram editor to see how it's done. I believe I
was told that it's purely a generated editor with no hand written
changes, so that leads me to think it's a generator option...

Dear Ed,
Thank you very much for your kind help.
sorry again for basic question. Actually I am new in Eclipse.
I tried in the visualcomponentexample.java to access. if I run this class
as java application it gives the following result:
Enter a list of file paths or URIs that have content like this:
<?xml version="1.0" encoding="ASCII"?>
<visualcomponentprefix:componentDiagram xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:visualcomponentprefix="visualcomponenturi"/>
I tried to print diagram name(System.out.println(root.getName());) but it
print null;
(please give me (hint or link to a tutorial) how to print classes and
attributes etc. from this class)
if you dont mind, I can send you my application to your email address (it
will be helpful form me).
Following are the VisualComponentExample.java(from Tests Package) and
VisualDiagramEditorUtil.java(from diagram package) classes.
sorry for too much code.

SO that seems promising since it implies you have an XMIResourceImpl
and this serialization appears to match the one you were showing before.

It's pretty clear that the above instance has not set any properties at
all so all of them will be returning their default value which most
typically is null.

You could, but at this point I'm still not sure the problem you have so
you'd need to be pretty clear what the problem is. I assume that in the
code you show below that you could call root.setName("abc") and then
you'd see it in your serialization. Doesn't the "else" case of the
example below correctly read the serialization you showed in another
posting? If not, what exception is being thrown? If so, you should
note that even in your previous example, there is no name property on
the root object in the resource. I imagine you could do something like
root.getHComponents() to access the list of all the hcomponents and that
each of these would have a name that would be non-null.

Dear Ed,
I set the values of the all comonents in diagam. and I set the name of
diagram in property window of the diagram that is
"diagramName-given-in-ropertyWindow"
and then I tried to access this diagram name in example.java and it
returned null.
when I set diagram name using root.setName("my diagram"); and run
example.java as java application it prints "my diagram";
and also I tried root.getHcomponents(); it prints "[]";
may be I am accessing it in wrong way. HComponent is container of other
components.
I am slso confused with if and else for args.length==0 (I need little
description for this plz.)
and also the extension of the file I am trying access is .visualcomponent.
as autogenerated. should it be as .xmi?
resource.getContents().add(root);
root.setName("my diagram");
root.getHcomponents();
System.out.println(root.getName());
System.out.println(root.getHcomponents());
resource.save(System.out, null);
the result is:
Enter a list of file paths or URIs that have content like this:
my diagram
[]
<?xml version="1.0" encoding="ASCII"?>
<visualcomponentprefix:componentDiagram xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"

That would be how an empty list is printed.

If there are no arguments to the command line invocation (you can
specify them in your launch configuration) then it creates a simple
example and serializes it. If there are arguments, it assumes these are
file paths or URIs pointing at a instance of your model and will load
them and validate them.

No, .visualcomponent should be fine, but you can also change it if you
like. The generate example will parse any extension the same way.

So it seems to me if you run the generated example with a command line
argument pointing at the file with the above serialization it will be
loaded correctly and then you'll be able to use your generated APIs to
walk the structure you've loaded. For example, after you load, try
doing resource.save(System.out, null) to see if it can write out the
same thing as it just finished loading. If that prints out the same
structure, you're set to go...

Why not. You have sample code that does it.

Again, you have sampel code that shows how to create an instance and
save it...

This saves to System.out and is like a "save as" to the given stream..
Using resource.save(null) will open a stream against the URI of the
resource itself and should save it in the give file. Within Eclipse
you'd usually use a URI.createPlatformResourceURI() with the full
workspace relative path instead.

The generated example shows how to load a resource. Use that approach.
Don't use the approach of using new directly on a resource impl (and one
that won't read XMI at that).

It's supposed to be an actual object contained by your resource. But
you haven't loaded the resource.

I would highly recommend that you get the example program working
without modifying it first. Specifying the path for a file in the
command line should load it properly.

You're still using "new XMLResourceImpl". The generated example uses
resourceSet.getResource(path, true). Why aren't you using the generated
code that actually works? Have you read the introductory overview ?
The Eclipse Modeling Framework Overview
< http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse. emf.doc//references/overview/EMF.html>
The "Saving and Loading Resources" section will be helpful to answer
your questions. It's a little frustrating that a fully functional
generated example that acts as a basic Java command line utility for
loading a resource doesn't get you started in the right direction

This object isn't in the resource. You'd have to add it to the resource
like the first part of the generated example shows.

I tried to do as you advised and errors are gone but it prints the

I want to write the properties of function node but it is writing the
ecore attribute names of function node in xmi format instead of text
format. <br>
following is the code in example.java.
<br>
<br>
<br>
URI
path=URI.createFileURI("C:/eclipse/workfolder/runtime-EclipseApplication/run/my.txt ");
<br>
XMLResource xmlResource = new XMLResourceImpl(path);
System.out.println("Loaded " + path);
<br>

You're still using "new XMLResourceImpl".
