IObjectList customers = vfs.CreateTypedObjectList(typeof(Customer)); foreach (Customer currentCustomer in someOtherList) customers.Add(currentCustomer);
//If a customer has a single contract IObjectList result = OclPs.Execute(customers, "self.contract");
//If a customer has many contracts IObjectList result = OclPs.Execute(customers, "self.contracts");
//If the association is one way from contract to customer IObjectList result = OclPs.Execute(customers, "Contract.allInstances->select(currentContract | currentContract.customer->includes(self))");
Might not compile though :-) |
