QUESTION
I am trying to learn the decorator pattern implementation in C++. I have tried implementing the decorator class using both a reference and pointer to the decorated object as a member (composition). A single invocation of decorator works expectedly. However, when I try chaining together multiple decorator instances, it works only when I use the pointer to the decorated object as a decorator class member. For the implementation with the decorated object reference, it fails unexpectedly (please see the output below). I am using GCC with C++11 enabled. Here's the code. The class RedRose is a decorator using the pointer to the base interface while class BlueRose uses the reference to the base interface. I am sorry if I am making a naive mistake but what am I missing?

QUESTION
def decorator_function(original_func):
def wrapper_func():
print('Run this code before the function that needs docorated')
original_func()
print('Run this code after the function that needs decorated has been called')
return wrapper_func()
def function_needing_decorated():
print('I need to be decorated')
decorator_test = decorator_function(function_needing_decorated)
