Entity Framework provides three methods for loading related entities: lazy loading, eager loading, and explicit loading. First, let's take a look at msdn's definition of three methods for loading objects.
Lazy Loading: For
What is the phase, compile, and run time of class loading in 1.ClassLoader java? is class loading the same as class loading?: Of course, during the run, I have an understanding of the misunderstanding, corrected as follows: Compile time compiler is not to load class, only responsible for compiling, go to rt.jar take data, not still is class file, JVM is as long a

Jquery implements image pre-loading and delayed loading, and jquery implements delayed loading.
This article describes how Jquery implements image pre-loading and delayed loading. Share it with you for your reference. The specific analysis is as follows:
There are many proje
Lazy loading is delayed loading and delay loading.When to load with lazy, I can only answer to lazy loading with lazy loading.As for why lazy loading, is when we want to access the amount of data is too large, obviously with the cache is not appropriate,Because the memory capacity is limited, in order to reduce the con
In development, if an instance is created that consumes a lot of system resources, we typically use lazy loading mechanisms, which means that this instance is created only when this instance is used, which is widely used in singleton mode. The implementation of this mechanism in single-threaded environment is very simple, but there are hidden dangers in the multi-threaded environment. This article focuses on the lazy

The loading in the game are now very beautiful, but in the final two types, static loading and dynamic loading.A static loading may be a background picture. And the dynamic loading is the reading of a thing in the "circle".1. Static Loading:Advantages: Read the scene using synchronous method is possible, because it is
Include delayed loading and greedy loading, include delayed Loading
Greedy loading:Gu mingyu is to read all the things to be loaded once.
Using (var context = new MyDbContext () {var orders
{Var orders = from o in context. Orders. Include ("OrderDetails") select o;
}
When reading the order information orders, we want to read the Order details, so here we useIncl

In the process of PHP development, if you want to introduce a class from the outside, you will typically use the include and require methods to include the file that defines the class. This is not a big problem when it comes to small-scale development. However, in large-scale development projects, doing so generates a large number of require or include method calls, which makes the code difficult to maintain without compromising efficiency, and the cost of require_once is great.Before PHP5, each

A while ago, received an app Chettu to make a load of the circular progress bar task, see that small progress bar turn, I thoughtfully ... At the same time, an Impressionist to do the control design of the students have recently made a revision, the control landing takes some time to see him on the Loading
Currently, the common platform written by client/server side requires plug-ins. Each plug-in is hosted in a dynamic library. In Symbian, dynamic calling is not very convenient, now let's summarize the loading methods of various types of libraries.

Reprinted from: http://chenzhou123520.iteye.com/blog/1597597The Java Virtual Machine specification does not have a mandatory constraint on when to start the class loading process, but for the initialization phase, the virtual machine specification strictly stipulates that there are only four cases where the class must be "initialized" (while the load, validate, prepare phase must start before this), and These four cases are categorized as follows :1.
The order in which a webpage is opened is based on the order from top to bottom of the page. To make the advertisement do not affect the page opening speed, you must wait until all the pages are opened and then load the JS Code. How to load the page before loading the advertisement:

See descriptions in one-to-many links in detail.and Cascade, translated as "Cascade", indicating the principle of cascading links, such as Tuser's cascade set to all, it is indicated that if the attack on the user policy operation, the requirements of the user's policy is also carried out the same operation. If you perform a save operation on the user policy, it is necessary to perform the save operation on the address of the user policy.Beg
The form of synchronous loading and asynchronous loading1. Synchronous loading
This is the type of synchronous loading that we usually use most often:
Synchronous mode, also known as blocking mode, blocks subsequent processing of the browser, stops subsequent parsing, and therefore stops subsequent file loads (such as images), rendering, and code execution.
