The first is GDT and the corresponding selector. We only define three descriptors, which are 0 ~ 4 GB executable segment, a 0 ~ A 4 GB read/write segment and a segment pointing to the memory start address: ; GDT; Segment Base Address segment boundary, attr

Java. Lang. classloader is provided in the Java class library as the base class of the class loader. Java Virtual Machine andProgramBoth call the loadclass method of classloader to load classes. However, classloader is an abstract class. The real loader must be a subclass of classloader. The classloader itself is also a Java class and needs to be loaded. A bootstrap class

Passerby One:Principle One: ID is the path principle.Usually our entrance is like this: require ([' A ', ' B '], callback). The ' A ' and ' B ' are moduleid. The loader knows the path of the JS to be loaded by the corresponding principle of ID and path. In this case, it is BASEURL + ' a.js ' and BaseUrl + ' b.js '.But the correspondence between ID and path is not always as simple as in the AMD specification by configuring Paths to assign a path to a s

frameworks have emerged. The famous one is Universal-Image-Loader, I believe many of my friends have heard of or used this powerful image loading framework. Today, this article introduces and uses this framework, mainly to help those who have never used this framework. This project exists on Github. Of course, the features listed above may not be complete. If you want to know some other features, you can only find them through our usage. Next, let'

Boot Loader is independent of the operating system and must be designed by the user. The Linux release package does not contain Boot Loader. However, you can directly use or refer to some open-source Boot Loader software projects. The implementation of boot loader is highly dependent on hardware, including the process

Canvas --- Canvas image loading, using the javascript callback mechanism to implement an image loader, javascriptcanvas The drawImage method of canvas has a disadvantage, that is, when the image has not been fully loaded, calling it will be ineffective. Of course, you can ignore this problem directly in the high-speed main loop of the game, or use img. complete = true for determination. You can use the img. onload = function () {}; callback solution o

The Java virtual machine uses the class loader to load classes into memory for use. In this process, the ClassLoader does a lot of things, such as reading byte arrays, validating, parsing, initializing, and so on. The URLClassLoader class provided by Java can easily load a jar, class, or network resource into memory. Tomcat uses a factory class classloaderfactory to encapsulate the details of creating the ClassLoader, which makes it easy to create a c

1. Concept:As the name implies, the ClassLoader (class loader) is used to load Java classes into a Java virtual machine. In general, Java virtual machines use Java classes in the following way: Java source programs (. java files) are converted to Java bytecode (. class files) after being compiled by the Java compiler. The ClassLoader is responsible for reading the Java byte code and converting it into java.lang.Class an instance of the class. Each suc

of the descriptor is run-time calculation after filling in the corresponding location, because our program is loaded by the BIOS or DOS, we do not know the segment address, so we do not know the program runtime in memory location.Now, loader is loaded by ourselves, the segment address has been identified as Baseofloader, so the physical address of the label (variable) appearing in loader can be represented
