20 * The message return graph node implementation.<br>
21 * This class differs on the AsynMessage class only on the drawing line style (dashed instead of plain line).<br>
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>
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>
29 * @see org.eclipse.linuxtools.tmf.ui.views.uml2sd.core.AsyncMessage AsyncMessage for usage example
