Chain of Responsibility Pattern
- Chain of responsibility pattern is used to achieve lose coupling in software design.
- A request from a client program is passed to a chain of objects to process it.
- Then the object in the chain will decide who will be processing the request and whether the request is required to be sent to the next object in the chain or not.
Example
- A good example Chain of Responsibility pattern is an ATM machine. The user enters the amount to be dispensed and the machine dispense amount in terms of defined currency bills such as €50, €20, €10.
- If the user enters an amount that is not multiple of 10, it throws an error.
- If one element in the chain is not able to process it fully, it sends the request to the next processor in chain to process the remaining request.
- If the processor is not able to process anything, it just forwards the same request to the next chain.

While the internet has enabled the sharing of knowledge in ways that previous generations could only have dreamed of, it has also provided ample proof of the line, often attributed to Winston Churchill, that "A lie gets halfway around the world before the truth has a chance to get its pants on". https://www.bbc.com/news/blogs-trending-37846860
