inline

Get edge's average travel time.

Returns

Travel time, in ticks.

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

capacity	Capacity to be added/updated.
usage	Usage to be added.
travel_time	Travel time to be added, in ticks.
modes	Update modes to be applied.
