// Simple example demonstrating how to expose 'function's

// can be called as 'function' in script.
var ScriptEngineManager = Java.type("javax.script.ScriptEngineManager");
// create manager
var manager = new ScriptEngineManager();
// create engine
var engine = manager.getEngineByName("js");
// Any lambda (@FunctionalInterface annotated type) object can be
// be exposed from script embedding code. Script can call
// it as a function
engine.put("upper", new java.util.function.Function() {
apply: function(x) x.toUpperCase()
