lazy programmer

Go from program HorizonI heard that married to marry programmers, money more words less die early. This is mostly the programmer's own black. Programmers have a very special sense of humor a group, good at self-deprecating, the courage to black, strong tolerance, a lot of things Wucken, not to be able not to endure the crown an anger. However, it is such a nice person, there are some things that can not stand.Changes in demandWhy is the "demand change" ranked first?Because someone said: Kill a

In the previous article, I talked about association mappings. The purpose of the association mapping is to make the object-oriented queries load the entity information associated with the entity at the same time, avoid two queries, and improve the convenience of the query, so that the object-oriented operation can better cover the function of SQL. But there is a problem to consider: the loading of the associated entity must be to occupy the program resources. The use of associated entity informa

Lazy Load is a jQuery plug-in written in JavaScript. It can delay loading a picture in a long page. Pictures outside the viewable area of the browser are not loaded until the user scrolls the page to their location. This is exactly the opposite of how the picture is preloaded. Delaying loading of pictures in long pages that contain many large pictures can speed up page loading. The browser will enter the ready state after the visible picture is loade

This approach help

Why do I need to delay loading? Because it will improve efficiency, the existence is reasonable, haha. General settings lazy loading is on the Object relational map (on many sides). For example: A user has multiple consumption records. Set to lazy, when querying the data will only take out the consumption record (more than one side), do not query the user (this does not improve efficiency, that is, the ass

We often see a lot of Web pages that are not loaded on the page, but browse to the current picture location. How did this come about?In fact, this is now the more popular "lazy load" technology, inspired by Matt Mlinac produced by the Yui Imageloader Toolbox.Later, a more complete jquery plugin was formed: jquery.lazyload.js.Here's how to use Jquery.lazyload.js:Lazy Load relies on jQuery.

With the oclazyload you can load AngularJS modules on demand. This was very handy for runtime loading of Angular modules in large applications.' Use strict ';//Declare app level module which depends on filters, and servicesvarApp = Angular.module (' app ', [' ui.router ', ' oc.lazyload ']). config (function($stateProvider, $locationProvider, $urlRouterProvider, $ocLazyLoadProvider) {$urlRouterProvider. otherwise ( "/"); $locationProvider. Hashprefix (‘!‘); //You can also load via resolve$statePr

Spring's lazy load is designed to avoid unnecessary performance overhead, which is when data is actually needed to perform the load operation. Not only in spring, but also in the actual coding process, we should learn from this idea to improve the efficiency of our program.First we look at a configuration file:beans> beans> bean id= "creditservice" type=" Com.jader.service.CreditServiceImpl " lazy

method that is executed when the Destroy-method is destroyed by specifying the property.Syntax: explanation of lazy-init in spring Bean configurationThe default behavior implemented by ApplicationContext is to instantiate all singleton beans in advance (that is, dependency injection) at startup. Early instantiation means that as part of the initialization process, the ApplicationContext instance creates and configures all the singleton beans. Usually

deferred load 1. 1 Use lazy load meaning when querying data, in order to improve the performance of database query, try to use single table query, because single table query is faster than multi-table association query. If the query single table can meet the requirements, first query a single table, when the need to correlate information, and then associated with the query, when it is necessary to query the associated information called deferred loadi

PHP regular expression greedy mode and lazy mode greedy mode when a regular expression contains a qualifier that can accept duplicates, the common behavior is (on the premise that the entire expression can be matched) match as many characters as possible. Consider this expression: a. * B, which will match the longest string starting with a and ending with B. If you use it to search for aabab, it will match the entire character. PHP regular greedy mode

The so-called lazy load, write is its get method.Note: If it is lazy loading, it is important to be aware of whether there is already, if not then to instantiate2. Benefits of using lazy loa

In a JPA application, the performance of the application can be improved by lazy loading. This is no doubt, but lazy load does not mean not to load, at some point or need to load the data, then how to trigger this loading behavior can be more effective. Here I would like to say a little digression, the interview I will also look at the interviewee's opinion of jpa/hibernate, the answer usually contains a jp
