an opportunity and positive. But at the same time, the ability to call centers and customer service centers has made higher demands, are we ready to do so?How will the future change as the knowledge base of the "brain" of the call center is addressed in this changing environment? Based on the practice and research of the Knowledge Management Center of China (Knowledge Management Center of China,kmcenter) Knowledge

Modern mobile communication tends to provide high-speed transmission multimedia services. The birth of LTE family base stations effectively improves the coverage, throughput, and transmission experience of the system in hot areas. In the standardization process of LTE, the concept and technology of a family base station HomeeNodeB and HeNB came into being. Unlike traditional cell communication

The example in this article explains the transformations between the base class and the derived class in C + +. It will help to understand the object-oriented programming of C + +. Note here: The premise of this example is that the derived class inherits the base class in the form of public inheritance, with the keyword publicly. The specific analysis is as follows: The following procedure explains the exa

C # base and this -- From Rocky Ren 2. Basic Concepts Base and this are attributed to access keywords in C #. As the name suggests, they are used to implement access operations of the Inheritance Mechanism to satisfy access to object members, this provides a more flexible processing method for the polymorphism mechanism. 2.1 base keywords It is used to implement

Like the this keyword, It is abbreviated or replaced as an instance of the class (so it cannot call static and abstract members of the base class, however, this keyword is used to replace the instance of this class. The base keyword is used to replace the instance of the base class. Its usage is very simple. The form of accessing the

Transferred from: http://www.cnblogs.com/sujz/articles/2044365.htmlThe inheritance of derived classes is summarized as follows: How to Inherit Description Public The public and protected members of the base class are inherited by the derived class, preserving the original state Private Public and protected members of the base class are inherited b

C + + notes: Derived classes to base class conversions to accessibility to determine whether a conversion to a base class is accessible, you can consider whether the public member of the base class is accessible and, if so, that the conversion is inaccessible, otherwise it can be accessed. If it is public inheritance, both user code and descendant classes can

In Oo, the base class has two methods at most. The first method is interface, that is, the base class is abstract class. The most typical example is factory design pattern. the second approach is to provide a mechanism for base class, and then provide several virtual functions, allowing users to overload this class to achieve the purpose of "Customization. A typi

Where to use the virtual base class:Why avoid ambiguity caused by multiple public base classes in multi-layer inheritanceVirtual base class UsageWhen a derived class inherits a base class, the virtual base class is inherited by the addition of an Vsan keyword.In the program

/** This keyword* This keyword references the current instance of the class* Note: The This keyword cannot be used in static member methods, and the This keyword can only be used in instance constructors, instance methods, or instance accessors*//** Base keyword* The base keyword is used to access the members of the base class from the derived class;* Specifies t

When there is a common base class on multiple inheritance paths, the common base class will produce multiple instances (or multiple replicas) at a certain confluence of these paths, and the public base class can be described as a virtual base class if only one instance of the base
