Right now I the following:
1) A java interface.
2) A concrete java class that does not implement the aforementioned interface, but does contain a method signature matching every one of the methods defined in the interface.
Since I am unable to change the implementation of item 2, I would like to know if it is possible to make a method that accepts an instance of item 1 as an argument accept item 2 without a class cast exception.
It feels like the various weaving/coercion/AOP mechanics in Spring should make this possible, but I don’t know how to do it.
Is there a way to make this happen?
Yes, using dynamic proxies or byte-code rewriting. However, to me it seems like you’re looking for the
Adapter pattern.
