Comparison of C++builder and VCIn fact, a long time ago I wanted to write this article, the reason on the one hand is because I deeply feel that C + + Builder is indeed an advanced and powerful programming tools, but more importantly, I am convinced that C + + Builder can bring huge commercial benefits and productivity of the company greatly improved, I can prete
The builder pattern is defined in design mode as a pattern for building complex objects that often require multiple-step initialization or assignment to complete. So, in the actual development process, where do we fit the builder model? It is a good practice to use builder mode instead of multi-parameter constructors.We often face the writing of such an implement
In fact, the builder pattern is to create an inner class in the class and then the outer class constructor passes the pair image of an inner class, and then the return value in the set and get methods in the inner class is an internal class pair image, which makes it possible to implement the builder pattern well. In fact he is like StringBuilder in the append:string a= "a"; A.append ("Wo"). Append ("Shi").
When writing a popup, it can include the OK button, the Cancel button, the title bar, the Close button, the Minimize button, the content, the Maximize button and so on, but the content does not have to exist under different requirements, different requirements need to be free to mix these components, obviously each combination must be repeated coding. Separating these different, easy-to-change components and constructing complex objects step-by-stage with a

Builder mode, which separates the construction of a complex object from its representation, this allows you to create different representations for the same construction process. If you need to separate the construction of a complex object from its representation, you can create different tables during the construction process, we need to apply the "Builder mode", also known as "generator mode", to applicab

If we need to build a house, and we don't know how to build a house, we will find someone else to help us build a house.
Step 1:
Create a new House class House with the property of the House. Let's find the House builder interface HouseBuilder. If we want to build a bungalow, we will find PingFangHouseBuilder, which inherits from HouseBuilder, there are various methods to build a house, such as floor makeFloor and wall makeWall.
Step 2:

[' ID '
The
intention is to separate the construction of a complex object from its representation so that the same build process can create different representations.
Applicability
When creating complex objects, the algorithm should be independent of the parts of the object and how they are assembled.
When the construction process must allow the constructed object to have different representations. Understanding The builder model is primarily to separa

The factory class pattern provides the pattern of creating a single class, while the builder pattern is to centralize the various products to manage, to create composite objects, so-called composite objects that refer to a class that has different properties, in fact the builder pattern is the combination of the previous abstract factory pattern and the last Test. Let's look at the code:As before, a sender
Personal understanding of the application scenarioFor example, if you want to create instances of various types of cars, there are many types of cars, but the interface definition for creating each type of car may be the same, and this mode is used.Popular explanations of related concepts

The specific implementation of the interface to each type of vehicle is called co
The builder mode also belongs to the creation mode.
As the name suggests, a builder is the person who implements a product (Building). After a series of unified operations, they can complete a work and what kind of product is inseparable from the builder. For example, the old Li family now has a land that can be used for building land. It can be used to build a s

After being acquired by Adobe, Adobe is ready to turn flash into a development tool. For example, JBuilder, VS, and so on. Therefore, with Flex builder, it is literally like JBuilder. Therefore, it is a development tool and as3. It should be as3 after flash8. The original as2 designers suddenly felt that as3 had changed a lot, because t
