Chain-of-Responsibility Design Pattern Explained With Simple Example: Behavioural Design Pattern Category
by The Chain-of-Responsibility design pattern basically consists of a source of command objects and a hierarchical series of processing objects. Every processing unit will process only typical kind of commands and it will pass rest of the command to next processing unit, thus creating a chain of processing units and that’s why the name of this design pattern is Chain-of-Responsibility pattern. This pattern provides the idea of one of the best programming practice which is “loose coupling”. For Design patterns basic explanation see (Design Patterns Simplified Version).
