Let’s explain the pattern step by step ;

• The chain-of-responsibility pattern is a design pattern consisting of a source of command objects and a series of processing objects.This design pattern is situated insi behavioral patterns.
• Avoid coupling the sender of a request to its receiver by giving more than one object a chance to handle the request. Chain the receiving objects and pass the request along the chain until an object handles it.
• Launch-and-leave requests with a single processing pipeline that contains many possible handlers.
• An object-oriented linked list with recursive traversal.
