Member Function Documentation

NeighborDatabase::NeighborEntry & dtn::routing::NeighborDatabase::create	(	const dtn::data::EID &	eid	)
throw	(
	)

Query a neighbor entry of the database. If the entry does not exists, a new entry is created and returned.

Parameters

eid	The EID of the neighbor.

Returns

The neighbor entry reference.
