The image processing technology of computers is getting better and better, and many seemingly impossible things are now quite mature.Algorithm. But do you believe that there is an algorithm that can change the aspect ratio of an image while keeping the aspect ratio unchanged!We often encounter such a problem: the source image's aspect ratio is not consistent with the target's length and width. It would be a pity to cut a part of the image, and the image content is changed after the image is stre

A proxy is a common design pattern designed to provide a proxy for other objects to control access to an object. The proxy class is responsible for preprocessing messages for the delegate class, filtering messages and forwarding messages, and performing subsequent processing of the message after the class is executed. Before we talk about dynamic proxies, let's take a look at what a static proxy is, taking transaction control as an example.
1. Static
Many people may not know that dynamic Web pages can also be cached in the browser. The following is a PHP script as an example of how to set up a dynamic Web page in the browser cache
Set page expiration time to 1 hours
$duetime = 3600*24*30;
//Get browser will transfer to server last-modified Header
$modify _time = $_server[' http_if_modified_since ');
//When the browser accesses the webpage again w
On this basis I do some encapsulation, in order to make the call simpler, and increase the dynamic code debugging support, the same code only compile once support, code changes automatically recompile, code reference file automatic loading and manual loading functions.

Static Compilation: compile all the DLL and masterProgramAll are compiled into a main program.Dynamic Compilation: the compilation result is that the main program is the main program, and each module is each module.Static compilation and dynamic compilation can be used to set dynamic settings of project properties!Static link: the static link has written the functions in the library into the executable file
Dynamic:The main is to postpone the determination of the data type by compile time to the runtime.This problem actually involves two concepts, runtime and polymorphism. Simply put, the run-time mechanism allows us to determine the class of an object until run time, and to invoke the class object to specify the method.Now, let me think about the dynamic language features of OC. The dynamic characteristics of

I have seen a "rule engine", which is to write Java code directly in the application Web interface, and then save it, the rules will take effect, I have been very strange, how is this implemented? In fact, this is like JSP, the middleware is dynamically compiled into Java files, have been dynamically compiled into class, but also dynamically loaded into the ClassLoader. So, in essence, the pure Java Rule Engine is 100% achievable.1. Dynamic generation

1. Dynamic typeThe runtime only knows the type of the object, the dynamic type is very common in programming, the simple is that the ID type, such as the agent at the time of the custom, ID type. At the moment we sometimes set our own methods, unsure, what type of object is passed in, we also ID type, and then inside the method to determine the type2. Dynamic bin
