Detailed Description

The neighbor database contains collected information about neighbors. This includes the last timestamp on which a neighbor was seen, the bundles this neighbors has received (bloomfilter with age).

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.

Definition at line 202 of file NeighborDatabase.cpp.

void dtn::routing::NeighborDatabase::expire

(

const dtn::data::Timestamp &

timestamp)

trigger expire mechanisms for bloomfilter and bundle summary

Parameters

timestamp

Here is the call graph for this function:

NeighborDatabase::NeighborEntry & dtn::routing::NeighborDatabase::get	(	const dtn::data::EID &	eid,
		bool	noCached = false
	)
throw	(	NeighborNotAvailableException
	)

Query a neighbor entry of the database. It throws an exception if the neighbor is not available.

Parameters

eid	The EID of the neighbor
noCached	Only returns an entry if the neighbor is available

Returns

The neighbor entry reference.

void dtn::routing::NeighborDatabase::remove

(

const dtn::data::EID &

eid)

Remove an entry of the database.

Parameters

eid	The EID of the neighbor to remove.
