I am really sorry. I am unclear about the type. Can you verify what I know
is correct
I found an example java code which will consume lambda as an argument .
public class Main {
interface MyCalcLambda {
BigInteger run(BigInteger input);
}
public static void runCalc(MyCalcLambda calc) {
// ???
}
public static void main(String[] args) {
runCalc(a -> a.multiply(a));
}
}
So here MyCalcLambda is the type of lambda. Is that correct?. So I can
reify "MyCalcLambda" "run"
method like any other java interface as long as I know the type "
MyCalcLambda". Is that right?
Library am going to use is an opensource library. I just need to write a
layer in clojure so that It can be reused.So that shouldn't be big issue(I
hope).
