Builder model
In Gof, the foundation of design pattern reusable object-oriented software, it is said that the construction of a complex object is separated from its representation, so that the same build process can create different representations.
This remark, indefinitely. The creation of a complex object, usually composed of a number of child objects, and if an object can be created directly, it is not called a complex object. Because of the cha

Problem:
If we want to write a builder class, we can write as follows:
Class Person
{
Public:
Void BuildHead ();
Void BuildBody ();
Void BuildArmLetf ();
Void BuildArmRight ();
Void BuildLegLeft ();
Void BuildLegRight ();
};
But what should we do when we want to build a thin, fat, and tall person?
Of course, we will think of defining the class of the builder above as an abstract class, and then defining t

Introduction to Builders ' modelsThe builder pattern separates the construction of a complex object from its representation, allowing the same build process to create different representations. In other words, the build pattern is the object's creation pattern. The construction mode separates the internal representation of a product from the production process of the product, allowing a construction process to produce objects with different internal r

The needs of our developers in the actual project are varied, and sometimes we have to match the app's own design style, and sometimes we feel that the system's dialog box is not very free, so it's necessary to define a dialog for yourself.
Why use the builder mode

Builder mode definition:Divides the structure of a batch object into its representation, so that the same structure can have different representations.
The builder mode is used to create a complex object step by step. It allows users to construct an object only by specifying the class type and content of the complex object. Create an internal component with the internal component unknown. The

In a software system, you sometimes need to create a complex object, and the complex object is composed of the molecular objects of each part through certain steps.
For example, in a procurement system, if a buyer needs to purchase a batch of computers, the computer is a complex object in this actual requirement, it is made up of CPUs, mainboards, hard disks, video cards, chassis, etc. If the purch
Definition:
The construction of a complex object is separated from its representation, allowing the same build process to create different representations. Explanation:
An object (product) that may consist of several parts. For example, a car, mainly by the body, engine, tires, transmission system, and other components. These parts or systems are representations of objects. The builder model separates the construction process of the complex object fr
I. Overview
The Builder mode solves the following problems: When the objects to be created are complex (usually composed of many other objects ), we need to separate the process of creating a complex object from the representation (Display) of this object. The advantage of this is to build a complex object step by step, because parameters can be introduced in the construction process of each step, the presentation of objects obtained after the creatio

The builder pattern in the big talk design model refers to an example: McDonald's, KFC's hamburger no matter which store to eat, what time to eat, at least in China, the taste is basically the same. And that "fish incense shredded pork" is almost all the size of the restaurant restaurant has a dish, but can eat a myriad of flavors, this is why?Builder Pattern: Separates the construction of a complex object

The builder mode of the hook method is introduced.Builder mode In addition to the gradual construction of a complex product object, you can also use the Director class to more granular control of the product creation process, such as adding a class called Hook method (Hookmethod) Special method to control whether a call to a buildpartx (), is to determine whether a part of the product needs to be built. The return type of the hook method is usually
