The class Code provides apply methods with different arities (actually up to 9 parameters) to invoke a function simply by specifying its name and argument types.

Example:

    val url = new URL("http://scala-lang.org/classes/examples.jar");
    val obj = new Location(url) create "examples.sort";
    val ar = Array(6, 2, 8, 5, 1);
    obj[Array[Int], Unit]("println")(ar);
    obj[Array[Int], Unit]("sort")(ar);
    obj[Array[Int], Unit]("println")(ar);

The class Location provides a create method to instantiate objects from a network location by specifying the URL address of the jar/class file.

An update of the jar/class file should not break your code as far as the used class names and method signatures are the same.

Example:

    val url = new URL("http://scala-lang.org/classes/examples.jar");
    val obj = new Location(url) create "examples.sort";

The object Location can be used to instantiate objects on the same Java VM. It is just provided to illustrate the special case where resources are available locally.

Example:

    val obj = Location.create("xcode.Math");
    val x = obj[Int, Int]("square")(5);
