Yes.
It wouldn't solve the problem of the compiler error?
Yes. You will not need to cast anything. For example:
aClass = Class.forName( aClassName );
aMethod = aClass.getDeclaredMethod( "aMethodName", new Class[] {} );
aValue = aMethod.invoke( aClass, new Object[] {} );
The suggestion of KVC is one that could be the ideal answer, and it
would never have occurred to me. Thanks for that suggestion. Now the
question is whether it works with static methods.
It should. If not, file a bug report.
I have given it a try without success. Does anyone have the answer.
In the meantime I have just resorted to using multiple if statements
to match the class string to the method call.
Argh! Fainted.
Yeah, from what I had been reading it looked like I would have needed
to instantiate a dummy object just to get the info.
To get the info about what? The interface? You can use reflection for
that too:
aClass.getInterfaces();
Not the end of the world though. Looks like Obj-C would have been an
easier path :)
Indeed. Objective-C provides proper class methods. Sigh.
