simple objects

 I've written a couple of objects about. NET to SQL Server programming in the past, and found that the understanding is not very profound, here is a summary today.Why do you summarize it?Because imagine whether to do web development or desktop

Recently with a technical manager, he has a requirement that all queries are required to be objects than results, not maps, and that many objects are composed of many entities, all of which specialize in the knowledge of hibernate returning

-----The core of automated testing Object positioning should be the core of automated testing, in order to manipulate an object, you should first identify the object. An object is a person, he will have a variety of characteristics (attributes),

I. Introduction During software development, we often encounter situations where simple objects and composite objects are processed. For example, processing directories in the operating system is an example, because directories can contain separate

First, Introduction:In the front we learned the first 10 patterns in C # design pattern-Singleton mode, simple Factory mode, factory method mode, abstract Factory mode, builder mode, prototype mode, adapter mode, bridging mode, decorator mode,

First, the combination mode introduction:The combined mode decouples the internal structure of the client and complex elements, allowing the client program to handle complex elements as simple elements. Allows you to combine objects into a tree

1. Overview In the data structure, the tree structure is very important. We can apply the tree structure to the design mode. Example 1: multi-level tree menu. Example 2: files and folders   2. Problem We can combine simple objects into

In our usual development process, we are bound to encounter this situation: both simple objects and complex objects composed of simple objects, these simple objects and complex objects will be combined into a tree structure, when the client
