hi


I have a problem of verfier that all the instances of a meta class are disctinct, please if you could correct me the code that I put in places but that does not work.
***********************
public boolean valid() {
// TODO: implement this method
// Ensure that you remove @generated or mark it @generated NOT
EList<tp1.Type> types= this.getChildren();
for (int i = 0; i < types.size(); i++)
{
for (int j = 1; j < i; j++)
{
Object o1 = types.get(i);
Object o2 = types.get(j);
getChildren().equals(o2);

if (o1.equals(o2))
{
return false;
} }}
return true;
*****************************

And for the test I use the following code that calls the function Valid ()

******************
public void testValid() {
// TODO: implement this operation test method
// Ensure that you remove @generated or mark it @generated NOT
URI fileURI= URI.createFileURI("E:/runtime-EclipseApplication/mymodel/monmodel.tp1");
ResourceSet resourceSet= new ResourceSetImpl();
Resource resource= resourceSet.getResource(fileURI,true);
try{
resource.load(null);
}
catch(IOException e){
e.printStackTrace();}
if(resource.isLoaded() && resource.getContents().size()>0)
{
simplemodel mm=(simplemodel) resource.getContents().get(0);
if(mm.valid())
{
System.out.println("valid");
}
else{
System.out.println("non valide");}
}}

//fail();
}
************************************
thank you in advance

Given that EObject implementations must not override .equals and that all EObject containing lists must have unique contents, there will never be duplicates. You can use EcoreUtil.equals to test for structural equality. Of course your loops don't properly compare every pair of objects either.

Hi

As Ed M pointed out, all objects are inherently distinct by the memory address criterion.

What is your criterion for distinct/unique?

If for instance you require a name property to be distinct, then you need to code that as part of your equivalence testing method.

Regards

Hi

Ok so you need to check that getTName() is distinct. But what is a TName? Your earlier example suggests that it is an Object, so your earlier use of "==" should work. Much more likely a TName is a String, which you have not interned, so you must use "equals()".

Regards

Note that you might be able to express your constraint directly in the Ecore model. I.e., each EReference has a key's feature that you can populate with zero one or more attributes of the referenced EClass. The EObjectValidator will validate that the combination of these keys is unique among all instances by that reference's value.
