Hi all,

I am creating ecore file programmatically by using the code as follows. But I want to introduce unique ids for all the elements in the generated ecore file.

Currently, the file which I generated looks like the following ecore file.

ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry().getProtocolToFactoryMap().put
("*", new XMIResourceFactoryImpl());

Resource resource = resourceSet.createResource(URI.createURI("file://D:/send.ecore"));

resource.add(eObject);


<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore">
<ecore:EOperation/>
<ecore:EOperation/>
<ecore:EAttribute/>
</xmi:XMI>

You'd need to to have a specialized factory that creates a specialized
XMIResourceImpl that overrides this method to return true.

protected boolean useUUIDs()
{
return false;
}
