◆ Update()

void LinkGraph::BaseEdge::Update ( uint capacity,
uint usage,
uint32_t travel_time,
EdgeUpdateModes modes )

Update an edge.

If mode contains UM_REFRESH refresh the edge to have at least the given capacity and usage, otherwise add the capacity, usage and travel time. In any case set the respective update timestamp(s), according to the given mode.

Parameters
capacityCapacity to be added/updated.
usageUsage to be added.
travel_timeTravel time to be added, in ticks.
modesUpdate modes to be applied.
