class member function

From:http://www.cnblogs.com/shijingxiang/articles/5389294.htmlRecently, the thread pool needs to be encapsulated into a C + + class named ThreadPool. Call Pthread_create in the member function Exec_task of the class to start the thread execution

I used to think about how to call windows APIs such as wndclass and createthread in the class and how to use the member function address when passing in the function parameter address. For research, I wrote an example code: #include #include using

The derived class does not have access permission to the private member of its base class, and does not have access permission to the protected member of the base class object) private and protected members have access permissions. Because c ++ has

Here is a small example to illustrate how member functions are called in c ++. # Include Using namespace std; class Test {public: void funcMember () {cout (Const_cast (This); // int * ptr = (int *) (const_cast (This);

# Include Class Object {}; typedef int (Object: * sayfunc) (const char *); Class A: Public object {public: int say (const char * MSG) {STD: cout fun = fun; This-> Target = target ;}~ Controller () {} void dofun (const char * MSG) {// (Target-> *

1, unlike regular pointers, a pointer to a member does not point to a specific memory location, it points to a specific member of a class, rather than to a specific member in a particular object. Usually the clearest way to do this is to look at the

Implementation of tdstretch class The soundtouch class member function putsamples (const sampletype * samples, uint nsamples) is implemented as follows. According to the analysis in the previous article, the rate is a ratio. If it is greater than 1,

The above section has explored the identification of this pointer, and the contents of the class can be seen by the this pointer. Here, it is up to the this pointer to see how the member variables of the class are arranged.Let's look at an example.

First, a function pointer is a pointer to a set of functions of the same type, and a class member function we can think of similarly that it is a pointer to a member function of the same set of types in the same category, and of course the member

In IntroductionC ++Before the internal connection and external connection in, describe some concepts. 1. Statement A declaration introduces a name into a scope; In c ++, it is legal to repeat a declaration in a scope. The following are declarations:

1. Statement A declaration introduces a name into a scope;In C ++, it is legal to repeat a declaration in a scope.The following are declarations: Int Foo (INT, INT); // function pre-declarationTypedef int; // typedef DeclarationClass bar; //

In the previous article, we briefly introduced the surfaceflinger service in the surface mechanism of the Android system. The surfaceflinger service is started in the system process and is responsible for unified management of the device's frame

1 //For a derived class to override a base class member function, the object that invokes the member function is determined at the time of the program's compilation, that is, either a base class object or a derived class object, which can only be a

CcobjectCCObject.h:#ifndef __ccobject_h__#define __ccobject_h__#include "platform/ccplatformmacros.h"//cocos2d namespace ns_cc_begin// Declares the following kinds of pointers to the member variables of the corresponding class, which are later

In the previous article, we analyzed the creation process of the runtime Context Environment in the Android Application Window. It can be seen that each activity component has an associated contextimpl object, and it also associates with a window

The C language pointer is quite flexible, but it is also quite easy to make mistakes. Many C-language beginners, even the C-language veteran, are apt to stumble under the C-language pointer. But there is no denying that the position of the pointer

One, what is operator overloadOperator overloading can be divided into two parts: "Operator" and "overload". When it comes to overloading, it's not strange, it's a compile-time polymorphism, and overloading can actually be divided into function

First, what is operator overloadingOperator overloading can be divided into two parts: "Operator" and "overloaded". When it comes to overloading, this is a compile-time polymorphic, and overloads can actually be broken down into function overloads

----------------- The class member function cannot be a thread function ---------------------------Generally, C ++ class member functions cannot be used as thread functions. This is because the compiler adds a member function defined in the classThe

1. Why is a class on a derived hierarchy the same as a virtual function in the virtual table of each class?Because: the call to the virtual function is made by a virtual pointer + offset address, because the call to the virtual function is this way,
