Impl
Class CallByReference

java.lang.Object
  Impl.CallByReference

public class CallByReference
extends java.lang.Object

Call-by-reference example. This class, Impl.Types.MyRef and Example.Client3 demonstrate how to emulate call-by-reference in Java. You cannot simply modify ref and return something else, because Java actually uses call-by-value for reference types, too. The ref inside test() is a copy of the ref the caller passed to the method. Therefore, the user code needs to set its ref to the ref returned by test().
