Adapter mode what is adapter Mode The adapter mode is a structural mode that allows two unmatched interfaces to work together. The adapter mode allows two unmatched classes to work collaboratively by converting one interface type to another interface type that the client expects. The

I. Overview　Concept　　　　In fact, to give a life example, adapter mode can be analogous to adapters, such as Typec and USB adaptor, the original can only be connected to Typec interface, expand to be able to connect to ordinary USB; Here the adaptor on the one hand need to check on the Typec, on the one hand need as a USB jack.If you want to cite a Java example, take a look at the JDBC Chapter! A simplified UML diagram for JDBC (the middle of the xxx JD

Adapter modeFrom the name you can see that the adapter is for the interface mismatch, and the compatibility method made,Suppose we have an already existing class adaptee, some of which already exist and implement a good method MethodA. However, the client does not want to call this class, but instead wants to invoke a specific interface such as the target interface.So if you want to call the Adaptee.methoda

Design Mode in Android-adapter ModeAdapter Mode From the name, we can see that the adapter is a compatible Method for interface mismatch,Suppose we have an existing class Adaptee, and some of them have existing and implemented Methods methodA. But the customer does not want to call this class, but wants to call a specific interface, such as the Target interface.So if you want to call Adaptee. the methodA ()

The adapter mode makes it possible to work together those classes that would otherwise not work together because of incompatible interfaces.2. Issues to solveThat is, the adapter mode makes it possible for those classes that cannot work together because the

In Series 1, the RM and MPEG classes inherit the videomedia abstract class, while the videomedia class implements the imedia interface, which only provides the play () method. Ice soda is intended to provide RM, MPEG with different attributes and methods than audiomedia. For example, for Video Media, there should be a method to adjust the screen size, such as resize (). This method is not available for the imedia interface. So how does one provide the resize () method not available in the imed

experience reach a certain level, and it also means to summarize a lot of good design experience, however, it may not be the case that "no teacher can do anything", or you can say that, on the basis of level and experience, it is time for the system to learn the "mode, it is helpful to learn the experts' summary and verify your own shortcomings. This series of design patterns learning notes is actually a Learning Record for the book "Java and patterns. Adap
