However, with memory limitations, the list capacity is certainly limited. Also, creating a list of 1 million elements takes up a lot of storage space, and if we just need to access the
Defined in Gof:"Separating a complex build process from its object representation allows the same build process to produce different object behavior." ”The builder model can be divided into two steps to implement:1. Separate the complex build process and divide the entire process into several steps, each of which can be either a functional component setting or a parameter designation, and in a build method, these steps are strung together.2. Define a
Let's review the basic concepts of design patterns:definitionthe construction of a complex object is separated from its representation, allowing the same build process to create different representations.Builders Hide how the product is assembled, so if you need to change the internal representation of a product, you just need to redefine a builder.Practical Range1. When creating complex objects, the algorithms should be independent of the components of the object and the way they are assembled.

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
C # examples of the builder mode of the design mode,
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
