Public Methods

Method Description
DisconnectionHandler ( Connection con ) : void

We don't want to send on disconnected edges. So we remove said connections and edges!
ShouldClose ( ) : bool

We need to make sure we still have a way out of the tunnel maze, otherwise we could get an endless loop resulting in a stack exception. For now, we will simply ensure that one of our overlap or our overlaps overlap has at least one such connection. Furthermore, if we have a long chain of tunnels relying on one overlap, they will eventually all close after the top most peer which happens to be in their overlap closes.
TunnelEdge ( IEdgeSendHandler send_handler, Brunet.Tunnel.TunnelTransportAddress local_ta, Brunet.Tunnel.TunnelTransportAddress remote_ta, IForwarderSelector ias, List overlap ) : System

Outgoing edge, since we don't know the RemoteID yet!
TunnelEdge ( IEdgeSendHandler send_handler, Brunet.Tunnel.TunnelTransportAddress local_ta, Brunet.Tunnel.TunnelTransportAddress remote_ta, IForwarderSelector ias, List overlap, int remote_id ) : System

Constructor for a TunnelEdge, RemoteID == -1 for out bound.
UpdateNeighborIntersection ( List neighbors ) : void

When our tunnel peer has some state change, he notifies us and use that information to update our overlap, here we set the overlap.
