Recreational lab: recreate your command pattern

Going on vacation tomorrow so here is a lab:
Let's suppose you have an application where two J.V.M. cooperate across the wire (using some serialization).
Now consider things such as :
interface XY_R<X,Y,R> extends {X, Y => R} , Serializable {}
Some code using this (oos is an ObjectOutputStream and the code is in a static main) :

        XY_R<Double,Double, Double> func = { Double x, Double y => x+y } ;
        oos.writeObject(func);

        Double db = new Double(3.14);
        XY_R<Double,Double, Double> func2 = { Double x, Double y => x+y*db } ;
        oos.writeObject(func2);

• Experiment with more complex closures (embarking instance data)


• Rewrite a command pattern with that (so one J.V.M can send a command to be executed by the other J.V.M) .

Have fun !

Sad note: though this looks fun, deployment problems are tricky (unless you download dynamically the anonymous inner classes from the JVM which initiates ) ... so it's not such a good idea after all!

Plus: since generics are a compile-time thing it does not make much sense here in a dynamic context so better stick to interface MyCommand extends {LocalContext => Result } , Serializable {}
