Asynchronous Message
|
| An asynchronous message is a visual synonym of an asynchronous message. It adds no additional semantics; it is simply an example of the asynchronous message adapted for use on a communication diagram. This usage of the asynchronous message has the same form as an asynchronous message used on other interaction diagrams: a solid line with an open arrowhead directed from one lifeline to another (possibly reflexive). It is rarely used on a communication diagram as it does little to clarify the sequencing of messages. There is a single form of presentation in the three different types of interaction diagrams and the two different presentations of the timing diagram. |
