Package net.i2p.router.networkdb.kademlia

Class FloodSearchJob

java.lang.Object

net.i2p.router.JobImpl

net.i2p.router.networkdb.kademlia.FloodSearchJob

All Implemented Interfaces:

Job

Direct Known Subclasses:

FloodOnlySearchJob, IterativeSearchJob

abstract class FloodSearchJob
extends JobImpl

Try sending a search to some floodfill peers, but if we don't get a successful match within half the allowed lookup time, give up and start querying through the normal (kademlia) channels. This should cut down on spurious lookups caused by simple delays in responses from floodfill peers NOTE: Unused directly - see FloodOnlySearchJob extension which overrides almost everything. TODO: Comment out or delete what we don't use here. Note that this does NOT extend SearchJob.
