Accessing objects and navigating meta-levels in code

Revision as of 07:32, 24 March 2023

A single link in runtime is implemented in an IObject as an IObjectReference, i.e. a link that points to another object.

Then one can write:

If ((destinationMember as IObjectReference).ObjectInstance.asObject == null)

i.e. the member as a single link - does it have an object on the other end?

Note! ObjectInstance is always non-null - it's the object holding information about the link-end. It can be a nullObjectImpl, which is an object.
