As the name suggests, this pattern creates a chain of elements that pass on responsibility when called for in code. A collection of design patterns implemented in Python programming language. In this pattern, normally each receiver contains reference to another receiver. This pattern aims to decouple the senders of a request from its receivers by allowing the request to move through chained receivers until it is handled. Attention geek! Chain of Responsibility method is Behavioral design pattern and it is the object-oriented version of if … elif … elif … else and make us capable to rearrange the condition-action blocks dynamically at the run-time. State Pattern : A behavioural design pattern that can occur as objects in your code are aware of their current state, and thus can choose an appropriate behaviour based on their current state. In this window there is … The chain of responsibility pattern is used to achieve loose coupling in software where a specified request from the client is passed through a chain of objects included in it.

The pattern allows multiple objects to handle the request without coupling sender class to the concrete classes of the receivers. The main objective of this pattern is that it avoids coupling the sender of the request to the receiver, giving more than one object the opportunity to handle the request. This pattern allows an object to send a command without knowing which object will handle the request. Upon receiving a request, each handler decides either to process the request or to pass it to the next handler in the chain. Real-Time Examples of Chain of Responsibility Design Pattern. The Chain Of Responsibility is a dynamic pattern.

Chain of Responsibility Design Pattern is a chain of loosely coupled objects who all get a chance to process command/query. Each processing object contains logic that defines the types of command objects that it can handle; the rest are passed to the next processing object in the chain. In other words if an object that is a part of the system does not know how to respond to the given request it passes it along the object tree. code, Class Diagram for Chain of Responibility Method, Further Read – Chain of Responibility in Java.
