Mode definition
Separates the construction of a complex object from its representation, so that different representations can be created during the same construction process.
Use Cases
1. When different event results are generated for the same method and different execution sequence;
2. Multiple parts or parts can be assembled into one object, but the running results are not the same;
3. The product class is very complex, or the calling sequence in the product class produces different performanc
1 Builder Mode Concepts
1.1 Introduction
The builder mode is a step-by-step creation of a complex object that allows the user to control the object's construction process more finely without knowing the internal build details. This pattern is designed to decouple the process of building complex objects from its components, separating the representation of the build process from the part.The
1. Mode motivationBoth in the real world and in software systems, there are some complex objects that have multiple components, such as automobiles, which include wheels, steering wheel, transmitter and many other components. For most users, it is not necessary to know the assembly details of these parts, but rather to use a complete car, which can be designed and described by the builder mode, which separates the parts from the assembly process, crea
No one buys a car with only one tire or steering wheel. Everyone buys a complete car with multiple components, such as tires, steering wheel, and engine. How to assemble these components into a complete car and return them to the user is a problem that needs to be solved by the builder mode. The builder mode is also known as the generator mode. It is a complex creation mode with a low usage frequency. The

Mode Motive
Both in the real world and in software systems, there are complex objects that have a number of components, such as automobiles, including wheels, steering wheel, engine, and many more. For most users, it is not necessary to know the assembly details of these parts, but rather to use a complete car, which can be designed and described by the builder mode, which separates the parts from the assembly process, creating a complex object step
Builder mode, construction mode
Definition
The builder mode creates all the parts one by one, and thus creates a complete product object. The builder mode hides the product structure and product part construction process from the client, and separates the responsibility for directing the construction process from the responsibility of specific

And everyone at each stage is certainly not the same ah, I think it can be said that there are no two people in the world in this 5 stages of life is exactly the same, but people who live to 70 years of age, have experienced these stages is certain. In fact, this is an example of a more classic
Personal Understanding:
The construction of a complex object is separated from its representation, allowing the same build process to create different representations.
After searching for a number of builder models, I found that some of the builders ' goals were to encapsulate the product in different order, some of the same order of different products, the order was encapsulated in the director, and some were not encapsulated, but deferred to the

1. Concept of builders ' modelsdefinition: Separating a complex object construct from its presentation so that the same build process can create different representations;Core: Separation of construction and presentation, different representations of constructionDifferent from abstract Factory mode:(1) is similar to the abstract factory pattern because it can also create complex objects. The main difference is that the builder model focuses on the ste
Purpose:Separates the construction of a complex object from its representation, so that different representations can be created during the same construction process.
UML structure diagram:
Applicable to the following situations:
1) when creating complex objects, algorithms should be independent of the components of the objects and their assembly methods.
2) When the constructor must allow different representations of the object to be constructed.
Abstract base class:1)
The builder mode is the most complex creation mode. It is used to create a complex object that contains multiple components and returns a complete product object to the user, the builder mode focuses on how this complex object is created step by step. for users, there is no need to know the creation process and internal composition details, you only need to create a complete object to make a complex object
