Example 20 with I2NPMessage

use of net.i2p.data.i2np.I2NPMessage in project i2p.i2p by i2p.

the class ExploreJob method buildMessage.

/**
 * Build the database search message, but unlike the normal searches, we're more explicit in
 * what we /dont/ want.  We don't just ask them to ignore the peers we've already searched
 * on, but to ignore a number of the peers we already know about (in the target key's bucket) as well.
 *
 * Perhaps we may want to ignore other keys too, such as the ones in nearby
 * buckets, but we probably don't want the dontIncludePeers set to get too
 * massive (aka sending the entire routing table as 'dont tell me about these
 * guys').  but maybe we do.  dunno.  lots of implications.
 *
 * FloodfillPeerSelector would add only the floodfill peers,
 * and PeerSelector doesn't include the floodfill peers,
 * so we add the ff peers ourselves and then use the regular PeerSelector.
 *
 * @param replyTunnelId tunnel to receive replies through, or our router hash if replyGateway is null
 * @param replyGateway gateway for the reply tunnel, if null, we are sending direct, do not encrypt
 * @param expiration when the search should stop
 * @param peer the peer to send it to
 *
 * @return a DatabaseLookupMessage or GarlicMessage or null on error
