Software Design – Chain of Responsibility Pattern

This episode covers a pattern that is not as well known as some of the recent ones.  This time we look at the chain of responsibility pattern.  This is also our first foray into the behavioral patterns.  These may be techniques you have used without knowing they had a formal name or related pattern. The Chain of Responsibility Pattern Defined As always, we will start with the “Gang of Four” intent to set the stage for our discussion. “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.” This intent is a lengthy one. ...

Software Design – The Proxy Pattern

We continue a look at the structural patterns with a look at the proxy.  This is much like the flyweight we reviewed in the last episode.  However, it has a different focus.  The flyweight can be used to implement a form of proxy but is a solution to a large number of instances where this is a different goal. The Proxy Pattern Defined As always, we will start with the “Gang of Four” intent to set the stage for our discussion. “Provide a surrogate or placeholder for another object to control access to it.” That, once again, provides a short and simple description of our pattern.  The proxy saves us from having to instantiate an object before we start using it.  The proxy...
