20 | * The message return graph node implementation.<br> | |
df0b8ff4 | 21 | * This class differs on the AsynMessage class only on the drawing line style (dashed instead of plain line).<br> |
73005152 BH |
22 | * Message return are generally associated to a message. This means, they are connected to the same lifelines than the |
23 | * associated message but in the opposite direction and for a different event occurrence.<br> | |
24 | * <br> | |
25 | * WARNING: The association validity is not checked, it is not necessary to provide a valid association, not even needed | |
26 | * to set an association to drawn a message with a message return style.<br> | |
