Design Pattern Training using C# - Day 8 | Observer, Chain of Responsibility, and Iterator Design Patterns in C# What is the Behavioural Design Pattern in C#? Behavioural Design Patterns deal with the communication or interaction between Classes and Objects. The interaction between the objects should be in such a way that they are talking to each other and still they are loosely coupled. Loose coupling is the key to implementing the n-tier architecture. What is the Observer Design Pattern? According to GOF, Observer Design Pattern states Define a one-to-many dependency between objects so that when one object state changes, all its dependents are notified and updated automatically. The Observer Design Pattern is a Software Design Pattern in which an object (called a Subject) maintains a list of its dependents (called Observers) and notifies them automatically whenever any state changes by calling one of their methods. What is the Chain of Responsibility Design Pattern? According to the Gang of Four Definitions, the Chain of Responsibility Design Pattern states that Avoid coupling the sender of a request to its receiver by giving more than one receiver object a chance to handle the request. Chain the receiving objects and pass the request along the chain until an object handle it. In simple words, we can say that the chain of responsibility design pattern creates a chain of receiver objects for a given request. In this design pattern, normally each receiver contains a reference to another receiver. If one receiver cannot handle the request then it passes the same request to the next receiver and so on. One receiver handles the request in the chain or one or more receivers can also handle the request. What is Iterator Design Pattern? The Iterator Design Pattern allows sequential access to elements without exposing the inside logic. That means using the Iterator Design Pattern we can access the elements of a collection in a sequential manner without knowing its internal representations.
