I think your example is valid. I think that the pattern that I described just happens to be a different implementation. Think of the Bridge as you SlowAndQualityDrawing. Using the bridge pattern would leave the client code unchanged with no need to recompile the code. In software engineering, the adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern) that allows the interface of an existing class to be used as another interface. I am not sure that I see much of a difference though. You could implement other implementations of Bridge if you wanted. Example - Object Persistence API Example The main difference between an adaptor and a bridge pattern, is that a bridge pattern serves to decouple an abstraction class from its implementation, and an adaptor pattern converts the interface between classes with less inheritance. This pattern involves a single class called adapter which is responsible for communication between two independent or … Adapter pattern works as a bridge between two incompatible interfaces. Intention: The end product may look similar but the intention is different. A chart illustrating fingerprint ridge patterns (arches, loops and whorls) and fingerprint ridge characteristics (core, ending ridge, short ridge, fork or bifurcation, delta, hook, eye, dot or island, crossover, bridge, enclosures, and speciality). In contrast, the Container's public interface isn't relevant to the Strategy pattern. There are 2 parts in Bridge design pattern : Abstraction; Implementation; This is a design mechanism that encapsulates an implementation class inside of an … A wrapper as used in the Facade pattern is intended to simplify an interface to an external library. Bridge is a pattern that makes it easier to maintain code and add features. 2. An adapter is intended to bridge the disconnect between one interface and another. This pattern involves a single class which is responsible to join functionalities of independent or incompatible interfaces. Object Adapter Vs Class Adapter The adapter pattern we have implemented above is called Object Adapter Pattern because the adapter holds an instance of adaptee. Bridge Pattern Example This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces. The bridge pattern applies when there is a need to avoid permanent binding between an abstraction and an implementation and when the abstraction and implementation need to vary independently. There is also another type called Class Adapter Pattern which use inheritance instead of composition but you require multiple inheritance to implement it. Adapter pattern acts as a bridge between two incompatible interfaces. The official definition for the Bridge design pattern introduced by Gang of Four (GoF) is to decouple an abstraction from its implementation so that the two can vary independently. Differences. In the Bridge pattern, the Container serves as an Adapter to the Interface, allowing Container's public interface to vary independently of the implementation in the subclasses. The adaptor and bridge patterns are very similar. This means to create a bridge interface that uses OOP principles to separate out responsibilities into different abstract classes. Flyweight is a structural design pattern that lets you fit more objects into the available amount of RAM by sharing common parts of state between multiple objects instead of keeping all of the data in each object. The Bridge design pattern allows you to separate the abstraction from the implementation.It is a structural design pattern.
