template<class TNodeData , class TEdgeData >

int TNodeEDatNet< TNodeData, TEdgeData >::AddEdge	(	const int &	SrcNId,
		const int &	DstNId
	)

Adds an edge from node SrcNId to node DstNId to the network.

If the edge already exists return -2. If the edge does not exist and was successfully added return -1. Normally the function should return an ID of the edge added but since edges in TNodeEDatNet have no IDs we return -1. Function aborts if SrcNId or DstNId are not nodes in the network.

int TNodeEDatNet< TNodeData, TEdgeData >::AddEdge	(	const int &	SrcNId,

	)

Adds an edge and edge data from node IDs SrcNId to node DstNId.

If the edge already exists, set edges data and returns -2. If the edge does not exist and was successfully added returns -1. Normally the function should return an ID of the edge added but since edges in TNodeEDatNet have no IDs it returns -1. Function aborts if SrcNId or DstNId are not nodes in the network.
