Guava: Set + Function = Map?

Question

Is there an idiomatic way to take a Set and a Function, and get a Map live view? (i.e. the Map

Answer 1

For the non live view the code exists in lambdaJ with Lambda.map(Set, Converter).

Set setKs = new Set();
Converter converterKv = new Converter{
    @Override
    public V convert(K from){
        return null; //Not useful here but you can do whatever you want
    }
}
Map mapKvs = Lambda.map(setKs, converterKv);

I tried my own implementation : http://ideone.com/Kkpcn As said in the comments, I have to extends another class so I just implemented Map, that's why there is so much code.

There is a totally useless (or not ?) feature that allows you to change the converter on the fly.
