Accessing objects and navigating meta-levels in code

Latest revision as of 05:28, 23 August 2024

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 is the object holding information about the link-end. It can be a nullObjectImpl, which is an object.
