that the "machining process" of the builder pattern is exposed, which makes the builder model more flexible, and the builder mode decouples the assembly process and creates the specific parts, so we don't have to care about how each part is assembled.

you want? I will create an object, the assembly sequence is not his concern.
C ++ implementation:
There are at least four categories: product, abstract construction, specific construction, and director. Product provides specific implementation interfaces, and abstract construction provides unified methods for specific construction classes, A specific construction class contains a commodity object and implements a specific method. The director class contains an abstract construction class object
What is Builder mode
The builder pattern is primarily designed to eliminate the complexity of other object creation processes.
Design Scenarios
There is a user's UserInfo class, create this class, need to create user's name, age, money and other information in order to obtain the user specific information results.

3, migrant workers , he is responsible for the implementation of specific things.Java code
Migrant. Responsible for the construction of specific parts such as windows and floors.
At the same time because the house is built by migrant workers, so after the completion of the building by him to return the house to the landlord
Public class Mingong implements Builder {
private String window="";
private String floor="";
builder, define the method of painting six parts, each painting a kind of person, create a new class to inherit the builder, so the new class must implement the builder's method, here the main use of the abstract method of the characteristics, here to solve the problem of painting a part. Build a leader class director, enter a builder class, define a draw method
The 11th chapter of the design pattern-builder mode (Java implementation) "I was drunk in that restaurant 、、、" "What's the matter?" "The Order of serving, the first dessert, then a cold drink, then the dish or something, no words dead." "That's a bit of a order, too." However, it is very rare, normal if it is Chinese food, are cold dishes before the hot dish, th

First, UML diagramSecond, the conceptBuilder Mode: separates the construction of a complex object from its representation so that the same build process can create different representations.Third, the descriptionRole:(1) Builder: is the abstract interface specified for each part of the product object that is created.(2) ConcreteBuilder: is the concrete creator, implements the builder interface, constructs a
Builder Pattern is a design pattern that creates shapes, and uses multiple simple objects to build a complex object step-by-step.Main Solution: The main solution in the software system, sometimes facing the creation of "a complex object", which is usually made up of the sub-objects of the various parts with a certain a
This article continues to introduce the builder model of the 23 design pattern series.Definition: Builder mode: Separates the construction of a complex object from its representation so that the same build process can create different representations.Practical scope 1, when the algorithm to create complex objects shoul
Builder mode: Separates the construction of a complex object from its representation so that the same build process can create different representations. (Go to "Big talk design Mode").After learning this pattern, I do not know how to compare with the previous simple factory model, and found that both are created objects. But the two are still different, and th
. Do not know how to handle the reasonable?
In addition, after writing a few articles about implementing design Patterns in Java code, it is found that this builder builder pattern seems to combine abstract factory patterns with template method patterns. The above paragraph has said my doubts, as for the abstract fact
Builder mode: Separates the construction of a complex object from its representation so that the same build process can create different representations.
Pattern implementation:
[Code]class builder;//Product class product{public:void Addpart (const char *info) {m_partinfovec.push_back (info); } void Showproduct () {for (std::vector
Client:
[Code]int Main () {
Iterators are a pattern of behavior in design patterns that provide a way to sequentially access individual elements in an aggregated object without exposing the object's internal representation. Python advocates the use of generators, which are also one of the iterators.Series Articles
