Return type binding

[A. Sundararajan]

I think you can use javax.script.Invocable API

ScriptEngineManager m = new ScriptEngineManager();
ScriptEngine e = m.getEngineByName("nashorn");
// your script may evaluate to a Person (script object) instance
Object obj = e.eval("... your script here...");
Invocable invocable = (Invocable)e;
MyInterface infObj = invocable.getInterface(obj, MyInterface.class);

Hope this helps,
