Auto Load Loader class A. OverviewThe system calls the Loader::register () method to register for automatic loading, and after this is done, all conforming class libraries, including the third-party class library that the Composer relies on for loading, are automatically loaded. The automatic loading of the system consists of two parts:1. Automatic loading method of registration system \think\
At the beginning of android3.0, a new loader was added. Loader the way the data is loaded is asynchronous.Features of loader:1. Suitable for activity and fragment2. Provides an asynchronous load data mechanism3. Monitor the data source and pass new results when the data source changes4. Automatically reconnect to the last data

Boot-loader and a CE 6.0 system have been preset in the digi CC 9p Development Board. Therefore, we can directly start the development board to run an ce 6.0 operating system. However, our ultimate goal is to develop a CE 6.0 platform, so we need to set some system variables
Classes in Java are dynamically loaded. Let's take a look at our common class loading methods first. We have a perceptual knowledge before we can furtherFor further discussion, class loading is nothing more than the following three methods.Class {}Class B {}Class C {}Public Class Loader {Public static void main (string [] ARGs) throws exception {Class AA = A.

Java class loader and java class loadingClass loading process
JVM divides the class loading process into three steps
The following three steps are involved:
JVM divides the class loading process into three steps:Load (Load), Link and initialization)The link is divided into three steps, as shown in:
1) load: Find and load binary data of the class;
2) link:
Verify: ensure the correctness of the loaded class;
Preparation: allocate memory for static

Windows CE inherits the rich functions of windows, but windowsCE is not a general installation version of the operating system. In the world of various embedded devices, a CE system is usually only generated for a certain hardware platform.Generally, the development process of Windows CE can be divided into three steps: 0al (OEM transaction action layer), driver, and application development. Among them, the most basic step of 0al development is the board-level support package (BSP), while the bo

to understand the class loader, first understand the loadI. Loading of classes (overview of loading classes)When a program wants to use a class, if the class has not yet been loaded into memory, the system initializes the class by loading, connecting, and initializing three steps.1. Loading
This means reading the class file into memory and creating a class object for it.
When any class is used, the system creates a class object.

ObjectiveJava reflection, the most commonly used Class.forName () method. At completion, the code string is received and the code string is generated by Javacompiler (stored in the bin directory in the Eclipse Project, under Classpath), and then through the Java reflection mechanism, the main method is obtained and executed. The class file name is fixed. When the A.class file is updated, the problem occurs, and the result of the execution of the main method is the same as the result of the first
When using jquery mobile development, sometimes we need to display the load prompt box during the request for Ajax (for example: a rotated picture + a hint: loading ... )。 This time, we can manually display the jquery mobile loader, the approximate process is as follows:1. Boot loader, display "Loading ...";2. Make an AJAX request, update the page data after the request is completed, and refresh the jquery
