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

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

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
In a software system, it is sometimes necessary to create a complex object, and the complex object is composed of a combination of steps by its various molecular objects.For example, in a procurement system, if a buyer to purchase a batch of computers, in this actual demand, the computer is a complex object, it is CPU, motherboard, hard disk, video card, chassis and other assembled, if at this time to let a buyer a computer to assemble the words are really tired buyers, In this case, we can use

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
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.

The following is my understanding of the builder model. I have not applied it in development. This is just my understanding of books. Builder Mode
Builder mode: separates the construction of a complex object from its representation, so that different representations can be created during the same build process.This is the standard expression of the
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

"I will tell you about the builder mode in the design mode. The builder mode is used to create complex objects step by step. It allows users to build complex objects by specifying the types and content of complex objects. Users do not know the specific internal build details ."
"Hey, isn't this similar to the abstract
In design patterns, the creator (builder) mode is defined to separate the construction of a complex object from its representation, so that the same construction process can create different representations. I believe most beginners do not understand this sentence.
In fact, the Creator mode is to create a complex object step by step. It allows users to build complex objects by specifying the types and content of complex objects. users do not know the
Some people who know siwft know that ring is a very core component of swift and determines how data is distributed in the cluster. Swift determines the number of partitions in the Cluster Based on the configured partition_power (2 to the power of partition_power), and based on consistent hashAlgorithmAllocate partitions to different nodes and distribute data to corresponding partitions.
Therefore, building a ring is a process that swift initialization must go through. Simply put:

The Separates the build of a complex object from its performance so that the same build process can create different manifestations. The look at this concept, may feel very abstract, can understand but do not know what use. Let's make an analogy to understand the definition above. Before we make a metaphor, let's talk about what this design pattern is for. Why do we use this model? The builder model is responsible for decoupling th
