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

the same method of the scene, different execution order, produce different event results, multiple parts or parts can be assembled into an object, but the result is different, the product class is very complex, or the order of call in the product class produces different performance, This is a good time to use builder mode, when initializing an object is particularly complex, such as many parameters, and many parameters have default values. 2

Folder: Views of UML Nine types of UML diagrams The relationship between classes in UML In this article, we present a view of UML that includes one or more diagrams in each view. This article focuses on the details of each diagram in UML:1. Case

Author: zyl910I. background Currently, many commonly used UML tools do not support objective-C, which is inconvenient to draw UML. You must manually convert the objective-C syntax parameter list to the UML or C ++ syntax. It is laborious and error-prone.So I want to write a tool that automatically converts the parameter list of objective-C syntax to

Uml and other diagrams, Uml In object-oriented processing, class graphs are at the core and provide the main rules for defining and using objects. It is a diagram describing classes, interfaces, and their relationships. It shows the static structure of each class in the system and is a static model. I. Class Diagram 1. Class A class is the basis for creating a class chart. It defines a group of objects wit

In the first part, we have established the understanding that UML is a language used to develop the components of software systems and the standard of interactive methods. UML involves 6 major aspects-from use-case models, dynamic and logical models, to final physical deployment models, and extension mechanisms that allow special annotations to be added to models.So, how do you use

　　When I mentioned UML before, I thought of the complicated flowchart. I admire the people who think about the UML diagram of the whole system, because they have the blueprint of the whole software architecture in their mind, so that when writing the implementation, they will know where to change and where to expand. And to be an architect, UML is also an ess

only for the creation of complex objects. There will be more than one product class in a system. These product classes do not necessarily have a common interface and may be completely unrelated, in this case, you need to provide multiple sets of abstraction and specific builders to create inconsistent products or use a unified interface to identify products. The UML diagram of the builder mode is as foll

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

There are many types of UML diagrams, only two of the most important and common-class and time series diagrams are discussed here. 1. Class Diagram through the class diagram, we can easily understand the code architecture, clarify the relationship between the modules, includes inheritance (inheritance), implementation (realization), dependency (dependency), composition (composition), Aggregation (Aggregation), Association (association), and so on. The

Classes may have the following relationships: Association, dependency, aggregation, aggregation, composition, and generalization, also known as inheritance), implementation (realization ). 1: Association refers to the relationship between two classes. For example, a customer and an order can only belong to one customer. A customer may have multiple orders. It can be divided into one-way and two-way directions. It can be divided into one-to-one, one-to-multiple, and many-to-many based on the corr

Easy introduction to UML (3)-SRP cook well, let others program, uml-srpA cook can make a good dish. Maybe he graduated from New Oriental or the secret recipe of his family. It is simple, happy, and efficient for you to let him cook a table of food. However, programming will become an annoyance and hard nut to crack. Maybe this metaphor is not very appropriate, but for every class, they are like an actor, ma

Three main elements of modeling: 1. Basic Construction blocks of UML; 2. Rules on how to put these constructor blocks together; 3. Some common mechanisms applied to the entire UML; The UML constructor consists of three types: A, thing B, relationship C, and diagram. Things: including "structured things", "behavior things", "grouping things", and "commenting thing
