in Unified Modeling Language (UML) sequence diagrams,
you can create lifelines and specify class names and types for lifelines
to develop interactions for C/C++ applications.
Creating lifelines
In Unified Modeling Language (UML) sequence diagrams, you can create lifelines to show how instances participate in interactions between C/C++ elements.
Deleting lifelines
You can delete lifelines from Unified Modeling Language (UML) sequence diagrams.
Terminating lifelines with stop nodes
In Unified Modeling Language (UML) sequence diagrams, when you create a destroy message, a stop node is created automatically on the lifeline. However, you can manually create a stop node on a lifeline to terminate the lifeline at a specific position.
Repositioning lifelines
In Unified Modeling Language (UML) sequence diagrams, you can move a lifeline to reposition the instance’s activity in an interaction frame. Although the horizontal order of a lifeline does not have semantic value in the project, you can move the lifeline horizontally to position it in a location that makes the diagram easier to read.
