21 | * The base UML2 syncMessages implementation.<br> | |
22 | * This abstract class only define one event occurrence to attach to the message.<br> | |
23 | * Usually a message has two event occurrences attached, one for both ends. But some syncMessages(like synchronous | |
24 | * syncMessages) only need one event occurrence to represent the time when they appear. Others kind of message | |
25 | * representations (like asynchronous syncMessages) will be responsible to define the missing second eventOccurrence | |
