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

// from embedding code. Any lambda object exposed to engine

// 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()

});

print(engine.eval("upper('hello')"));
