Nine types of UML diagrams
Relationships between classes in UML
As described above, the UML view includes one or more diagrams in each view. This article focuses on the details of each UML diagram:

The builder pattern is somewhat similar to the previous abstract factory pattern, but more powerful than the abstract factory pattern, the builder pattern can be seen as two parts, one builder, and the other is that the basic idea of Director,builder is the abstract factory, While the director exists to make the use of
Idea: Since the interstellar picture is made up of several parts: the map (the terrain and the minerals), the building, the troops. Then we think of them as parts, assembled to be the final product (the whole picture).
Builder (Builder) mode example:
The code is as follows
Copy Code
Specification of interfaces for manufacturing individual parts Interface
Key points of the builder mode:
The builder mode is mainly used"Build a complex object in steps ". In this case, "step-by-step" is a stable multiplication, while all parts of complex objects change frequently.
The builder mode mainly dealsFrequent demand changes for "various parts of complex objects. ItsDisadvantage:It is difficult to cope with changes in the dem

Not many computer players have not learned much, but with the continuous development of the project, those who have never seen before, and those who have never used them are all about to start learning. Although I have heard of UML for a long time, I have never read this book and have never used this tool. The class diagrams of UML are also unknown. Basically, I don't know how to understand it. I haven't us

I have recently prepared to study volley's source code, but I have read some blogs on the Internet. They all work with the diagram. This looks more intuitive and the analysis logic is also good, what kind of diagrams can clearly analyze the relationships between various types and how to extract them. So I first learned the modeling t
Builder mode Definition: separates the construction of a complex object from its representation so that the same build process can create different representations.The builder pattern is a step-by-step creation of a complex object that allows the user to build them only by specifying the type and content of the complex objects. The user is not aware of the specifics of the build internals. The

Generalization (generalization)Generalization relationship: An inheritance relationship that represents a general and special relationship that specifies ho
My understanding of the relationship between uml class diagrams and my understanding of uml class diagrams
Relationship between uml class diagrams:
Generalization is inheritance. An Implementation relationship is a class that implements another interface. Dependency is a class that uses another class. It is a usage relationship. In a service of this class, anothe

the created object to be inconsistent in its state. This will appear in multithreaded programs. For example, Cocacola.setsodium (35); Before executing this code, the object CocaCola has already been used by other threads, which results in the use of a CocaCola object that is not in the correct state. simply put, the object is created, and the code that sets the state of the object is not atomized. --------------------------------------------------------------------------------------------------

If the elements in UML are basic words, the view is the syntax.
Sort out the views in UML:
Static View:
As the name implies, a static view is a view that expresses static things. It only describes the static structure of a thing and its dynamic behavior. Examples, class charts, and package charts are provided.
Use Case Diagram: Use Case Diagram is the first step from software requirement analysis to fina
Data Center reconstruction (1) -- UML diagram, Data Center reconstruction -- uml diagram
Finally, we started restructuring. Data Center reconstruction is a very important small project at this stage, because it involves all kinds of knowledge we learned during this time. First, we used the knowledge of softwares, write the document before development, and then use the U
In UML, a link is very important. it abstracts the links between objects and forms a link structure. The following describes the four types of relationships in UML: association, dependency, generalization, and implementation. #160; #160; 1. Examples #160; #160; 1. Association #160; #160; associations are used to connect objects with structural relationships. they can be connected to the same class or

Today we look at another element of the UML basic building block-the relationship.in UML, there are relationships that represent the basic diagram symbols, which are: Dependency (dependency), generalization (generalization, also known as inheritance), realNow (realization) and Association (Association), and the association is divided into common associations (common Association), Aggregation (aggregation,
