      • setArgs

        public void setArgs​(int index,
                            Object arg)
        Sets the argument that is passed to the wrapped method. Note that using this method is only necessary if the parameters passed into the constructor do not act as references. For example, if an int value is passed in the constructor that int value will be automatically updated as a reference to some other int value. This method allows client code to set the value of that int.
        Parameters:
        index - the index into the argument array
        arg - the argument to pass to the method
      • getArgs

        public Object[] getArgs()
      • execute

        public void execute()
