hello, I have a scenario. I created the ecore model and I have an class named Reports. This contains certain field like date, some strings.
Is there a possibility to read the contents of the Reports (Model Object)and display the contents (in the client environment)
Its like Reports-> Right click -> a menu is generated and a sub item is like (read this report). On click this should read the contents of the model object(Reading logic resides in some class).
I skimmed through the book and it suggests to create wizards and wizard pages for the UI.
P.S: I can export it as a xmi file and read through the data. but I want it to be done like this.
Any suggestions.
Thanks

So you load the model into a resource and use something like to write it
to a string representation:
StringWriter writer = new StringWriter();
OutputStream out = new
URIConverter.WriteableOutputStream(writer, "UTF-8");
resource.save(out, null);
System.err.println(writer.toString());
You can invoke Generate Test Code to generate an XyzExample.java in the
*.tests project showing how to load a resource in a stand alone
application. If you're running in the Eclipse IDE, you don't need any
of the registration code, just a resource set to load the resource. Or
if you already have the model loaded, you can use eObject.eResource() to
get at the resource and use the code I show above write the whole thing
to a string.
