Message Synchronous
|
| A synchronous message is a visual synonym of a synchronous message. It adds no additional semantics; it is simply an example of the synchronous message adapted for use on a communication diagram. This usage of the synchronous message has the same form as a synchronous message used on other interaction diagrams: a solid line with a solid arrowhead directed from one lifeline to another (possibly reflexive). It has a different appearance from other forms of the synchronous message as it uses a Dewey decimal system (x.y.z) of message sequence labels that indicate the time ordering 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. |
