Hi Ed,
thanks a lot for fast reply. I found this option by following the thrown
exceptions.But I didn't find out how to I set this option, last evening.
So I set the option before I register my metamodel and voila
EMF skip the broken links and load the valid part of my datamodell.
My working Code:
public void load(String path) {
if (path != null && !path.equals("")) {
try {
File file = new File(path);
FileInputStream fin = new FileInputStream(file);
ResourceSet resourceSet = new ResourceSetImpl();
//Skip broken references and not existing classes
loadOptions = resourceSet.getLoadOptions();
loadOptions.
put(XMLResource.OPTION_RECORD_UNKNOWN_FEATURE,Boolean.TRUE);
EMOFResourceFactoryImpl loadFactory =
new EMOFResourceFactoryImpl();
resourceSet.getResourceFactoryRegistry()
.getExtensionToFactoryMap().put(
Resource.Factory.Registry.DEFAULT_EXTENSION,
new XMIResourceFactoryImpl());
resourceSet.getPackageRegistry().put(LogicPackage.eNS_URI, LogicPackage.eINSTANCE);
URI fileURI = URI.createFileURI(path);
Resource resource = resourceSet.getResource(fileURI,true);
resource.load(loadOptions);
this.sys =(Sys)resource.getContents().get(0);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
