## Detailed Description

simple dependency between objects.

You can inject this implementation into CBaseObjects whenever you need other CBaseObjects to be informed about changes to that class instance. Note that you need to handle recursions yourself and that no reference counting is done and that you must make sure that the dependent objects are alife while added as dependent.
