Do you see anyway around this? My parent class is a generic database

search_by(), a factory pattern that returns an object or objects
of its
own class that match the search. I see no way to define the database
table in a child class and have it passed back to a static
function in
the parent class.
you might want to override the parent classes implementation. or
create
an abstract method in parent that gets overriden in the child.
Ray, I'm not sure I understand.
By the way, it appears this issue is well documented in the comments
of the get_class() function. For example, another impossibility
raised by this bug is extending a Singleton class:

This comment seemed to summarize it well:
"Basically these design patterns, and various other meta
manipulations (things which operate on the nature of the object, not
on the data the object holds) could benefit greatly from knowing
exactly what the final type of this object is, and not having native
access to this information obligates work-arounds."
