Adding constructors and destructors in a UML class diagram for C++ classes

Question

在为C++代码编写UML类图时，是否需要包含相关类的构造函数和析构函数？

Answer 1

In many cases, adding constructors/destructors to a C++ class diagram would just be textual boilerplate noise and not really meaningful. Only if you want your diagram to be a complete documentation of your C++ classes, you may want to add constructors.

Contrary to what @Marco is saying below, this is not a matter of the underlying business logic, but a purely ergonomic issue of avoiding cluttering and noise in (typically complex) diagrams.

Answer 2

The constructor can be added if it's part of the business logic, you just don't add a return type.
Would be under the functions/methods section:
+ClassName()
I would not add destructors. Again, depends on whether your business logic needs it.
