Hi All,
Coming in late, but though I might be able to help.
Rony, from your post I guess we're talking about a function that is
shared across all your sites. You want the function to be able to
take a "Test" class from any of the sites as an argument, but you
can't dynamically change the argument type.
What you need to do is make a base class called (say) AbstractTest in
a "core" package shared by all applications:
com
L ronycorp
L core
L AbstractTest.cfc
...then have the Test component in each application extend AbstractTest:
com
L ronycorp
L core
L AbstractTest.cfc
L app1
L App1Test.cfc
L app2
L App2Test.cfc
...
L appN
L AppNTest.cfc
In AppNTest.cfc:
<cfcomponent extends="com.ronycorp.core.AbstractTest">
With this you can now rewrite your function without a dynamic class
name:
<cfargument type="com.ronycorp.core.AbstractTest"...
Meaning that the argument has to be a "kind of" AbstractTest to be ok
- this is taking advantage of polymorphism to stop your core code
having to depend on a specific, concrete AppNTest class to work (you
already tried this with the #app# idea, this is just a more
conventional O-O way to do it).
There is a name for this idea of having plugin classes that inherit
from a common base class and implement things their own way: it's the
"Template Method" design pattern.
HTH,
Robin
