In Unified Modeling Language (UML) sequence diagrams,
you can create, edit, and reposition messages on lifelines to develop
interactions for C/C++ applications.
Creating synchronous or asynchronous messages
In Unified Modeling Language (UML) sequence diagrams, you can add synchronous and asynchronous messages to lifelines to represent the communication between interaction instances. You can also specify the operations, or methods, of messages.
Adding create or destroy messages to lifelines
In Unified Modeling Language (UML) sequence diagrams, you can add create messages or destroy messages to lifelines to represent the creation or the destruction of interaction instances. You add a create message above any messages and interaction fragments that are covered by the lifeline; you add a destroy message below the messages and interaction fragments.
Deleting messages
You can delete messages from sequence diagrams or delete them permanently from all diagrams and projects. When you delete a message, you have different results depending on the type of message that you delete.
Delaying the receipt of asynchronous messages
In Unified Modeling Language (UML) sequence diagrams, you can move the sending point and the receiving point of an asynchronous message between lifelines to manipulate the time delay between the sending event and the receiving event. Multiple messages can occur between the sending and receiving lifelines.
