void ANSimMobility::extractDataFrom (  cXMLElement *  node  )  [protected]

Utility: extract data from given <position_update> element. { // extract data from <position_update> element // FIXME start_time has to be taken into account too! as pause from prev element's end_time const char *startTimeStr = firstChildWithTag(node, "start_time")->getNodeValue(); const char *endTimeStr = firstChildWithTag(node, "end_time")->getNodeValue(); cXMLElement *destElem = firstChildWithTag(node, "destination"); const char *xStr = firstChildWithTag(destElem, "xpos")->getNodeValue(); const char *yStr = firstChildWithTag(destElem, "ypos")->getNodeValue(); if (!endTimeStr || !xStr || !yStr) error("no content in <end_time>, <destination>/<xpos> or <ypos> element at %s", node->getSourceLocation()); targetTime = atof(endTimeStr); targetPos.x = atof(xStr); targetPos.y = atof(yStr); }

void ANSimMobility::fixIfHostGetsOutside (   )  [protected, virtual]

Overridden from LineSegmentsMobilityBase. Implements LineSegmentsMobilityBase. { raiseErrorIfOutside(); }

void ANSimMobility::initialize (  int   )  [protected, virtual]

Initializes mobility model parameters. Reimplemented from LineSegmentsMobilityBase. { LineSegmentsMobilityBase::initialize(stage); EV << "initializing ANSimMobility stage " << stage << endl; if (stage == 1) { nodeId = par("nodeId"); if (nodeId == -1) nodeId = parentModule()->index(); // get script: param should point to <simulation> element cXMLElement *rootElem = par("ansimTrace"); if (strcmp(rootElem->getTagName(),"simulation")!=0) error("ansimTrace: <simulation> is expected as root element not <%s> at %s", rootElem->getTagName(), rootElem->getSourceLocation()); nextPosChange = rootElem->getElementByPath("mobility/position_change"); if (!nextPosChange) error("element doesn't have <mobility> child or <position_change> grandchild at %s", rootElem->getSourceLocation()); // set initial position; setTargetPosition(); pos = targetPos; updatePosition(); } }

void ANSimMobility::setTargetPosition (   )  [protected, virtual]

Overridden from LineSegmentsMobilityBase. Implements LineSegmentsMobilityBase. { // find next <position_update> element with matching <node_id> tag (current one also OK) while (nextPosChange) { const char *nodeIdStr = firstChildWithTag(nextPosChange, "node_id")->getNodeValue(); if (nodeIdStr && atoi(nodeIdStr)==nodeId) break; nextPosChange = nextPosChange->getNextSibling(); } if (!nextPosChange) { stationary = true; return; } // extract data from it extractDataFrom(nextPosChange); // skip this one nextPosChange = nextPosChange->getNextSibling(); }
