existing classes, and the interfaces of this class do not meet the needs of the system.2. You want to create a reusable class that works with some classes that are not too much related to each other, including some that might be introduced in the future. These source classes do not necessarily have very complex interfaces.3. (for object adapters) in the design, you need to change the interfaces of several existing subclasses, and if you use the class's adapter pattern, you should make an adapte

available, the resource is freed when unlocked, and the mutex is added to 1, indicating that there is another available resource.Semaphores (Semaphore) are similar to mutexes, which indicate the number of available resources, unlike mutexes, which can be greater than 1. Its related operation functions are:#include Here is a demonstration of the use of semaphores with examples of producers and consumers of a finite resource pool:#include Read/write Lock (Reader-writer lock)A read-write lock is a

to use deep copy at this point.A icloneable interface can be implemented in a standard way. If you use this interface, you must implement the Clone () method that it contains. This method returns a value of type System.Object. We can use a variety of processing methods to execute the selected method body to get this object. Deep replication is possible if you prefer (but the execution process is not required, so you can perform a shallow copy as needed). See chapter 11th.(original) C # learning

engine (which can be steam engines, diesel engines, etc.). But this class is abstract, because there is no "normal" train. To create an actual train, you need to add features to the train. To do this, derive some classes, such as: Passengertrain, Freighttrain, and 424DoubleBogey, as shown in 9-14.　　The Car object series can also be defined in the same way, using car abstract base classes, which derive from the compact, SUV, and Pickup,car and train can even be derived from the same base class a
