Interfaces and factories for the base I2P SDK used to develop applications that communicate through I2P.
Implementation moved to net.i2p.client.impl in 0.9.21.
When a client application wants to communicate over I2P, the first thing it
needs to do is get a
I2PClient from the
I2PClientFactory. If it does not already have a
Destination, it must generate one with the
I2PClient.createDestination(java.io.OutputStream) before proceeding. Once it has
one, it then creates an
I2PSession which serves as the
bridge to the I2P network, allowing it to send messages (via
I2PSession.sendMessage(net.i2p.data.Destination, byte)) and receive messages (via
I2PSession.receiveMessage(int)). In addition, the client
receives asynchronous notification of network activity by providing an implementation
This client package provides the basic necessity for communicating over I2P, but there are three other subpackages that are helpful. Specifically:
net.i2p.client.datagram- for applications that want their messages to be both authenticated and repliable
net.i2p.client.naming- for applications that want to resolve readable names into
- net.i2p.client.streaming - for applications that want to use a streaming API to provide reliable in order message delivery (note: the streaming library is packaged seperate from the main SDK - in the mstreaming.jar and streaming.jar)
I2PSession implementation itself communicates with
the I2P router by the I2CP (the client protocol).
Interface Summary Interface Description I2PClientDefine the standard means of interacting with the I2P system An I2PClient contains no state, it is just a facility for creating private key files and generating sesssions from existing private key files. I2PSessionDefine the standard means of sending and receiving messages on the I2P network by using the I2CP (the client protocol). I2PSessionListenerDefine a means for the router to asynchronously notify the client that a new message is available or the router is under attack. I2PSessionMuxedListenerDefine a means for the router to asynchronously notify the client that a new message is available or the router is under attack. LookupResultThe return value of I2PSession.lookupDest2() SendMessageStatusListenerAsynchronously notify the client of the status of a sent message.
Class Summary Class Description I2PClientFactoryProvide a means of hooking into an appropriate I2PClient implementation I2PSimpleClientSimple client implementation with no Destination, just used to talk to the router. SendMessageOptionsAdvanced options attached to a single outgoing I2CP message.
