6.  def cons[T](f: JavaConsumer[T]): Function[T, Unit]

   Creates a Function of T to Unit from a com.twitter.function.JavaConsumer.

   Creates a Function of T to Unit from a com.twitter.function.JavaConsumer.

   Allows for better interop with Scala from Java 8 using lambdas.

   For example:

   import com.twitter.util.Future;
   import static com.twitter.util.Function.cons;
   
   Future<String> fs = Future.value("example");
   Future<String> f2 = fs.onSuccess(cons(s -> System.out.println(s)));
   // or using method references:
   fs.onSuccess(cons(System.out::println));

   excons if your function throws checked exceptions.

   func if you have a function which returns a type, R.

   func0 if you have a function which takes no input.

    exfunc if your function throws checked exceptions.

    func0 if you have a function which takes no input.

    exfunc0 if your function throws checked exceptions and takes no input.

    cons if you have a side-effecting function (return type is Unit or void)

14.  def func0[T](f: Supplier[T]): Function0[T]

    Creates a Function0 of type-T from a java.util.function.JavaSupplier.

    Creates a Function0 of type-T from a java.util.function.JavaSupplier.

    Allows for better interop with Scala from Java 8 using lambdas.

    For example:

    import com.twitter.util.Future;
    import static com.twitter.util.Function.func0;
    
    Future<String> fs = Future.apply(func0(() -> "example"));

    Note

    as this was introduced after util dropped support for versions of Java below 8, there was no need for a JavaSupplier like class.
