difference between bridge pattern and adapter pattern

Adapter pattern acts as a bridge between two incompatible interfaces. Adapter pattern works as a bridge between two incompatible interfaces. In contrast, the Container's public interface isn't relevant to the Strategy pattern. An adapter is intended to bridge the disconnect between one interface and another. 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. This pattern involves a single class called adapter which is responsible for communication between two independent or … There are 2 parts in Bridge design pattern : Abstraction; Implementation; This is a design mechanism that encapsulates an implementation class inside of an … This pattern involves a single class which is responsible to join functionalities of independent or incompatible interfaces. 2. Think of the Bridge as you SlowAndQualityDrawing. Intention: The end product may look similar but the intention is different. Bridge Pattern Example 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. Differences. 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. I think that the pattern that I described just happens to be a different implementation. Using the bridge pattern would leave the client code unchanged with no need to recompile the code. 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. 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). A wrapper as used in the Facade pattern is intended to simplify an interface to an external library. I am not sure that I see much of a difference though. I think your example is valid. The adaptor and bridge patterns are very similar. 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. Example - Object Persistence API Example This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces. The Bridge design pattern allows you to separate the abstraction from the implementation.It is a structural design pattern. You could implement other implementations of Bridge if you wanted. 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. Bridge is a pattern that makes it easier to maintain code and add features. 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. This means to create a bridge interface that uses OOP principles to separate out responsibilities into different abstract classes.
