The class file binary character stream is loaded into memory (method area) through the ClassLoader and virtual machines. After the layout and initialization of the memory, the virtual machine bytecode execution engine can execute the functions defined by the relevant code implementation program. The object that the virtual machine execution engine executes is a m

1. First, you need to install Apache service, here does not describe how to install. 2. First configure window virtual domain to open hosts Path is C:\WINDOWS\SYSTEM32\DRIVERS\ETC After opening, write the domain name in the inside like www.cms.com 3. Modify the Apache configuration file httpd.conf Found it Remove the note Modify To open state 4. Modify Apache under Httpd-vhosts.conf The example path is: D:\wamp\bin\apache\apache2.4.9\co

Introduction has never written a conceptual article, because I think that these conceptual things are written in the books and are very detailed and useless, and today I have a whim to write, Here is a discussion of the virtual base class, virtual functions and pure virtual functions, a look at the name of the people can easily feel confused. But don't worry,

C ++ virtual functions and virtual function table Parsing1. Definition of virtual functions A virtual function must be a non-static member function (and a non-constructor) of the class. Its access permission can be defined as private or proteceted, but it is meaningless for polymorphism .), Define the general form of

Preface The migration technology of virtual machines provides a simple method for server virtualization. Currently, popular virtualization products VMWare, xen, hyper-V, and KVM all provide their own migration tools. Among them, the Linux platform's open-source virtualization tool KVM has developed rapidly, and the migration features of KVM-based virtual machines have become increasingly improved. This arti

Virtual functions (virtual keyword) and polymorphism one: A pointer problem in inheritance. 1. A pointer to a base class can point to a derived class object. When a base class pointer points to a derived class object, the pointer can only access those members of the derived object that inherit from the base class, and cannot access the elements that are unique to the subclass, unless the coercion type con

4.2 Virtual Member Functions (dummy member function)Have seen the general implementation model of virtual function: Each class has a virtual table containing the address of the function virtual function in the class, then each object has a vptr, pointing to Virtua where table is located.in order to support the
