Good example of decorator pattern

Hi Every one mostly talks about decorator pattern with pizza example. I got idea about usage of this pattern as it helps avoid class explosion. However, Could someone please suggest a good example apart from pizza for decorator pattern?

Ketan Lalcheta , Please add a python tag. Two good examples of real-world uses of Python decorators I saw on YouTube were timing how long a function takes to execute and writing a log entry every time a function executes.

Ketan Lalcheta , OK. I see. "The DecoratorPattern is a pattern described in the [1994] DesignPatternsBook. ... This is not to be confused with PythonDecorators ..." -- https://wiki.python.org/moin/DecoratorPattern How unfortunate that the names are so similar.

Yeah. Thats why I had not tagged any language as this is generic to all. Also , i had no sample code for this question to make it specific to any language.

Rain i am afraid it is not the same thing. Python decorators are related to functions. This is related to design patterns and class where we avoid multiple classes.

You are talking about decorator from python. This is the concept which is applied to functions. AFAIK, method / function decorator is limited to Python only. Is this correct? Now, coming to my query. My concern is not related to function decorators. This is a generic concept applicable to all object oriented programming language.
