15 Sequence Diagram Asynchronous Message. Messages messages are arrows that represent communication between objects. The order in which these interactions take place.
The ability to distinguish synchronous from asynchronous messages means that sequence diagrams can be used to model concurrent processing. One way to think of sequence diagrams, particularly figure 6 includes an asynchronous message, the message to the system printer which has the partial arrowhead. Learn about sequence diagram notations, how to draw sequence diagrams and best practices to an asynchronous message is used when the message caller does not wait for the receiver to process the message and return before sending.
To depict flow of control and to predict object life time so you know when it's safe to delete them.
15 Sequence Diagram Asynchronous Message. If you're reading a sequence diagram, beware of making assumptions. Once the message is received, both sender and receiver are working simultaneously. After creating a sequence diagram, you may want to adjust the length of lifelines to clean up the diagram. What is a sequence diagram?
