Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.
It is safe to call GetObject() from within this method.

Finds the appropriate entry which must be used in order to forward a data packet to a next hop (given a destination).
Imagine a routing table like this: [A,B] [B,C] [C,C]; being each pair of the form [dest addr, next-hop addr]. In this case, if this function is invoked with [A,B] then pair [C,C] is returned because C is the next hop that must be used to forward a data packet destined to A. That is, C is a neighbor of this node, but B isn't. This function finds the appropriate neighbor for forwarding a packet.
| [in] | entry | The routing table entry which indicates the destination node we are interested in. |
