bool dht::Database::checkToken	(	const dht::Key &	token,
		const KNetwork::KInetSocketAddress &	addr
	)

	token	The token received
	addr	The address of the peer

Returns:: true if the token was given to this peer, false other wise

bool dht::Database::contains ( const dht::Key & key ) const

Test whether or not the DB contains a key.

Definition at line 227 of file database.cpp.

void dht::Database::expire ( bt::TimeStamp now )

Expire all items older then 30 minutes.

Parameters:

now

The time it is now (we pass this along so we only have to calculate it once)

dht::Key dht::Database::genToken ( const KNetwork::KInetSocketAddress & addr )

Generate a write token, which will give peers write access to the DB.

Parameters:

addr

The address of the peer

Returns:: A Key

Definition at line 143 of file database.cpp.

void dht::Database::insert ( const dht::Key & key )

Insert an empty item (only if it isn't already in the DB).

Definition at line 232 of file database.cpp.

void dht::Database::sample	(	const dht::Key &	key,
		DBItemList &	dbl,
		bt::Uint32	max_entries
	)

Get max_entries items from the database, which have the same key, items are taken randomly from the list.

If the key is not present no items will be returned, if there are fewer then max_entries items for the key, all entries will be returned

Parameters:

	key	The key to search for
	dbl	The list to store the items in
	max_entries	The maximum number entries

Definition at line 99 of file database.cpp.

void dht::Database::store	(	const dht::Key &	key,
		const DBItem &	dbi
	)

Store an entry in the database.

Parameters:

	key	The key
	dbi	The DBItem to store
