[designmode] adapter pattern

2. Basic introduction

1. Adapter pattern (Adapter Pattern) Convert the interface of a class to another interface representation that the client expects , The main purpose is compatibility , Allows two classes that would otherwise not work together because of interface mismatches to work together . It is alias wrapper (Wrapper)

2. Adapter mode belongs to structural mode

3. It is mainly divided into three categories ： Adapter like pattern 、 Object adapter pattern 、 Interface adapter mode

1. Examples of adapters in real life

The socket in Thailand uses two holes （ European standard ）, You can buy a multi-function plug ( Adapter ) , So you can use .

3. working principle

1. Adapter pattern ： Convert the interface of one class to another . Make classes that are not compatible with the original interface compatible

2. From the user's point of view, there is no adapter , It's decoupled

3. The user calls the target interface method transformed by the adapter , The adapter then calls the relevant interface methods of the adapter

4. Users receive feedback , It just feels like interacting with the target interface , Pictured
