This article mainly shows you the "Visual Studio 2010 sequence diagram is like", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "what the Visual Studio 2010 sequence diagram is like" this article.

About sequence diagrams

The sequence diagram represents the chronological order in which messages are sent between objects. Each meta-role is represented by a lifeline-that is, a vertical line is used to represent the lifetime of the object throughout the interaction. Arrows between lifelines

The connection represents the message. Sequence diagrams can be used to describe a scenario-the historical process of a transaction.

One use of sequence diagrams is to represent the order of behavior in a use case. When a use case behavior is executed, each message in the sequence diagram corresponds to a class operation or a trigger event in the state machine that causes the transformation.

We mainly look at the sequence diagram provided for us in VS2010. Here is the corresponding toolkit:

1. Lifeline lifeline, which represents the role or object instance modeled in the sequence. You can determine whether it is a role or object instance by setting its Actor attribute to true.

two。 Messages, including:

2.1 Synchronous synchronization messages

2.2 Asynchronous Asynchronous messages

3. Create is used to create lifeline elements and instances.

4. Comment comment tags (similar to those in other drawings)

5. Comment Link annotation chain wiring (similar to those in other drawings)

6. Interaction Use interactive applications for creating a reusable sequence or a reference to other sequences

CombinedFragment composite fragment

It can help us complete judgment, looping and other functions. The following figure shows the corresponding support in VS2010:

Generate sequence diagrams from code

1. In the right button of the method, you can see the menu that generates the sequence diagram:

two。 Here are some settings:

3. Once confirmed, it can be generated.

Interact with class diagrams

1. In the UML Model Explorer on the left, you can drag the class designed in the class diagram directly onto the sequence diagram to create a lifeline, as follows:

two。 Existing lifelines can also generate classes and interfaces:
