Dynamic Object type casting

["Bhamani, Nizar" <nizar.bhamani@proactcorp.com>]

All,

Here is my scenario :

Class baseclass;

Class derived1 extends baseclass;
Class derived2 extends baseclass;

Class derived11 extends derived1;
Class derived12 extends derived1;

Class derived21 extends derived2;
Class derived22 extends derived2;
Class derived23 extends derived2;
Class derived24 extends derived2;
...


I have a method that returns appropriate derived class based on parameter
passed :
i.e.    public baseclass[] method( "derived2" )  

where 'method' returns array of objects of type : either "derived21", or
"derived22", 
                                                      or "derived23", or
"derived24" ...

Is there a way for me to dynamically typecast this return values ?  

i.e. during the first call to method( "derived2" ) would return an array of
"derived21" objects
during the second call it could return array of "derived23" and so on...

Thanks in advance.
