But it wouldn't do anything useful. CFMX 7 only looks for
Application.cfc and only instantiates and executes the Application
object - it won't see anything that extends Application.cfc
Now, the one case where it *might* be useful is if you do what we do
on macromedia.com where we have /Application.cfm and
/appname/Application.cfm which starts out by <cfinclude>ing the root
Application.cfm file. Given an appropriate mapping, you could have a
root Application.cfc and then appname.Application could extend
root.Application (it couldn't just extend Application since that would
be in the same directory). Then each of your on*Start() methods could
begin by calling super.on*Start() and each of your on*End() could end
by calling super.on*End(). Nice, neat reuse (and this is a case where
inheritance is OK because an Application object is-a Application
object).
The other thing you could do is have your application start/end
methods defined in a tree of CFCs outside the webroot and then just
have each Application.cfc extend the appropriate CFC from the tree:
components/
BaseApplication.cfc
app1/
App1Application.cfc (extends BaseApplication)
app2
App2Application.cfc (extends BaseApplication)
webroot/
Application.cfc (extends BaseApplication)
app1/
Application.cfc (extends app1.App1Application)
app2/
Application.cfc (extends app2.App2Application)
You Application.cfc object would be completely empty - all of the
logic would be in the Base / App1 / App2 versions.
Not sure whether I think that's good practice or not...
