I am planning on developing a few child classes from a parent one. I noticed in SiteTree if I do a DataObject::get search for a page class, it will also return all child classes.
How does Silverstripe track ID's on child classes? Are all child class objects tracked in the parent table, too (by ID), or would I need to be careful e.g. a ChildClass starts from 1 and and a ChildClass with ID=1 may not be the same object as ParentClass ID=1?
Hope this makes sense.
