IConstraint Identity()

Sets the evaluation mode to identity comparison. In this case only objects having the same database identity will be included in the result set. For example:

var pilot = new Pilot("Test Pilot1", 100);
var car = new Car("Ferrari", pilot);
container.Store(car);
var otherCar = new Car("Ferrari", pilot);
container.Store(otherCar);
Query query = container.Query();
query.Constrain(typeof(Car));
// All cars having pilot with the same database identity
// will be retrieved.
query.Descend("pilot").Constrain(pilot).Identity();
