XofFactory

Factory class for implementors of Digest or Mac to wrap them in XofDelegate such that there is a distinct separation of functionality between those class types and Xofs, while still being able to share similarities/capabilities.

e.g.

class SHAKE128: SHAKEDigest {

    // ...

    companion object: XofFactory() {
        @JvmStatic
        fun xOf(): Xof = object : XofDelegate(SHAKE128()) {
            // ...
        }
    }
}
