Use this method to check whether a particular persistent object belongs to the current Object Space. If the object passed as the parameter belongs to another Object Space, this method retrieves the same object from the database via the current Object Space.
When implementing the IObjectSpace interface in the BaseObjectSpace class’s descendant, don’t implement the GetObject<ObjectType> method. It’s implemented in the BaseObjectSpace class. The BaseObjectSpace.GetObject<ObjectType>(ObjectType objectFromDifferentObjectSpace) method calls the BaseObjectSpace.GetObject(Object objectFromDifferentObjectSpace) method, which returns null. The latter method is virtual. So, you should override it in your descendant.
The following code snippet (auto-collected from DevExpress Examples) contains a reference to the GetObject<ObjectType>(ObjectType) method.
Note
The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
acceptor?.Invoke(obj);
var tobj = objectSpace.GetObject(obj);
var aobj = tobj as IAssignable<T>;
