Thread: how to wrap a pre-generics library

I'm a bit unclear as to why you want to do this...is it just to get rid of the warnings, or do you want more defined compile time type checks? For the former, you can use the @SuppressWarnings annotation. For the latter, I am not aware of a way to go about it other than wrapping it through delegation, or rewriting the library.

I would just add the generics, if you feel it is necessary. If the Maps and Lists are all internal and still work fine, just do @SuppressWarnings and forget about it. If they are public and part of the documentation, I would change them, as it will be confusing/annoying for programmers to work with your non-generics based Map/List as opposed to what they are used to.

EDIT:
You could, perhaps, wrap the classes by renaming the old ones (and remove public modifier so that they are 100% internal) and then just create some new rather short generics supported classes with the previous names. The new classes could just do some simple interfacing with the old ones through type-casting and such. I think Sun might've done that with JList in JDK7... but don't quote me on that
