Class HttpDiscovery

java.lang.Object

org.bitcoinj.net.discovery.HttpDiscovery

All Implemented Interfaces:

PeerDiscovery

public class HttpDiscovery
extends Object
implements PeerDiscovery

A class that knows how to read signed sets of seeds over HTTP, using a simple protobuf based protocol. See the peerseeds.proto file for the definition, with a gzipped delimited SignedPeerSeeds being the root of the data. This is not currently in use by the Bitcoin community, but rather, is here for experimentation.
