The main purpose of this article is to continue to focus our emphasis on the basic UML diagram; This month, we learn more about sequence diagrams. Again, please note that the example provided below is based on the new UML 2 specification. The purpose of the diagram Sequence

Figure 1: Empty UML 2 framework component In addition to providing a graphical border, the framework components used in graphs also have important functions to describe interaction, such as sequence diagrams. In a sequence diagram, a sequence receives and sends messages (also known as interacti

complete. Significant progress has been made in serialization logic modeling due to changes in the symbol set of the sequence diagram in UML 2 ). Note the text I mentioned above: "The uml2.0 draft Specification has been adopted ." Indeed, the specifications are still in the draft State, but the key is that the draft specifications have been adopted by OMG, which is an organization that uses them until the

procedure call self-correlating message (self-message) represents the method's own invocation and one method within an object that calls another method. Combined Fragments øalternative fragment (denoted "alt") corresponds to If...then...else øoption fragment (denoted "opt") and Switch corresponding to the Øparallel fragment (denoted "par") means that Øloop fragment (denoted "Loop") occurs simultaneously with the for or Foreach corresponding third, the time series

Various diagrams in UML are an important part of the UML model. In recent articles, I will introduce nine important diagrams in UML. The general content is shown in the following directory. 1. use case diagram, class diagram, and object Diagram 2. Sequence diagram and collab

1. Sequence diagram (Sequence Diagram) is used to display the relationships between objects, emphasizing the chronological order of messages between objects, and showing the interaction between objects. A sequence diagram is a tab

Implement UML sequence diagram and uml Sequence This article begins to discuss issues at the code level. It mainly refers to the design and implementation of the markdown function. This article begins with the code outside markdown:UML sequence diagrams are obtained from https://github.com/bramp/js-

make the image easier to read. (For example, the logical process of the model in UML 1.x is too complex and sometimes impossible to complete. Significant progress has been made in serialization logic modeling due to changes in the symbol set of the sequence diagram in UML 2 ).Note the text I mentioned above: "The uml2.0 draft Specification has been adopted ." In

first, the definition: Time series diagrams (Sequence Diagram), also known as sequence or sequential plots, are UML behavior diagrams. It shows the dynamic collaboration between multiple objects by describing the chronological order in which messages are sent between objects. It can represent the sequence of behavior o

6. Use the [iconix] method to design a blog [sequence diagram] In the previous articles, we performed domain model and case modeling respectively, and used the robustness tool for further analysis and verification.Based on the corresponding model (domain model), the related boundary pair is introduced through the robustness method.Control Object (Controller), and update the attributes (fields) of classes in

First, the problem analysisIn the case of violent resolution, the total number of cases considering the sub-paragraph is 1+2+...+n=o (n^2). Considering the dynamic programming algorithm, the complexity of O (n) algorithm can be realized.Second, the program designIii.

(6) If you need to set post-time space constraints, you can attach appropriate time and control constraints to each message. (7) Attach the front or back conditions to each message of a control flow, which can describe the control flow in more detail.V. Example of Time

They all indicate whether to go to or from an endpoint element.Lifeline Start and endLifelines can be created and destroyed in the sequence graph timescale range, and in the following example
