Quote Encyclopedia In computer programming, adapter patterns (sometimes referred to as wrapper styles or wrappers) fit the interface of a class to what the user expects. A fitting allows a class that is usually not working together because the interface is incompatible, by wrapping its own interface in an existing class. Basic Information There are two types of adapter modes: Class
Generally, the client class accesses the services it provides through the class interface. Sometimes, an existing class (existing class) can provide the functional requirements of the customer class, but its interfaces are not necessarily expected by the customer class. This is because the existing interface is too detailed or lacks details or the interface name is different from the one found by the customer class. In this case, the existing interface needs to be converted to the desired interf
