    • I2PTunnelClientBase

      public I2PTunnelClientBase(int localPort, Logging l, I2PSocketManager sktMgr, I2PTunnel tunnel, EventDispatcher notifyThis, long clientId) throws IllegalArgumentException
      This constructor is used to add a client to an existing socket manager.

      As of 0.9.21 this does NOT open the local socket. You MUST call startRunning() for that. The local socket will be opened immediately (ignoring the i2cp.delayOpen option).

      Parameters:
      localPort - if 0, use any port, get actual port selected with getLocalPort()
      sktMgr - the existing socket manager
      Throws:
      IllegalArgumentException
    • I2PTunnelClientBase

      public I2PTunnelClientBase(int localPort, boolean ownDest, Logging l, EventDispatcher notifyThis, String handlerName, I2PTunnel tunnel) throws IllegalArgumentException
      The main constructor.

      As of 0.9.21 this is fast, and does NOT connect the manager to the router, or open the local socket. You MUST call startRunning() for that.

      (0.9.20 claimed to be fast, but due to a bug it DID connect the manager to the router. It did NOT open the local socket however, so it was still necessary to call startRunning() for that.)

      Parameters:
      localPort - if 0, use any port, get actual port selected with getLocalPort()
      Throws:
      IllegalArgumentException - if the I2CP configuration is b0rked so badly that we can't create a socketManager
    • I2PTunnelClientBase

      public I2PTunnelClientBase(int localPort, boolean ownDest, Logging l, EventDispatcher notifyThis, String handlerName, I2PTunnel tunnel, String pkf) throws IllegalArgumentException
      Use this to build a client with a persistent private key.

      As of 0.9.21 this is fast, and does NOT connect the manager to the router, or open the local socket. You MUST call startRunning() for that.

      (0.9.20 claimed to be fast, but due to a bug it DID connect the manager to the router. It did NOT open the local socket however, so it was still necessary to call startRunning() for that.)

      Parameters:
      localPort - if 0, use any port, get actual port selected with getLocalPort()
      pkf - Path to the private key file, or null to generate a transient key
      Throws:
      IllegalArgumentException - if the I2CP configuration is b0rked so badly that we can't create a socketManager
  • Method Details

    • verifySocketManager

      protected void verifySocketManager()
      Create the manager if it doesn't exist, AND connect it to the router and build tunnels. Sets the this.sockMgr field if it is null, or if we want a new one. This may take a LONG time if building a new manager. We need a socket manager before getDefaultOptions() and most other things

    • getSocketManager

      protected I2PSocketManager getSocketManager()

      Returns:
      non-null
      Throws:

    • getLocalPort

      public final int getLocalPort()
    • getListenHost

      protected final InetAddress getListenHost(Logging l)
    • startRunning

      public void startRunning()
      Actually open the local socket and start working on incoming connections. *Must* be called by derived classes after initialization. (this wasn't actually true until 0.9.20) This will be fast if i2cp.delayOpen is true, but could take a LONG TIME if it is false, as it connects to the router and builds tunnels. Extending classes must check the value of boolean open after calling super.startRunning(), if false then something went wrong.
    • getDefaultOptions

      protected I2PSocketOptions getDefaultOptions()
      Create the default options (using the default timeout, etc). Warning, this does not make a copy of I2PTunnel's client options, it modifies them directly.
    • getDefaultOptions

      protected I2PSocketOptions getDefaultOptions(Properties overrides)
      Create the default options (using the default timeout, etc). Warning, this does not make a copy of I2PTunnel's client options, it modifies them directly. Do not use overrides for per-socket options.
    • optionsUpdated

      public void optionsUpdated(I2PTunnel tunnel)
      Update the I2PSocketManager.
      Overrides:
      optionsUpdated in class I2PTunnelTask
      Since:
      0.9.1

      Parameters:
      dest - The destination to connect to, non-null

      Since:
      0.9.9

      Create a new I2PSocket towards to the specified destination, adding it to the list of connections actually managed by this tunnel.
      Parameters:
      dest - The destination to connect to, non-null
      opt - Option to be used to open when opening the socket
      Returns:
      a new I2PSocket
      Throws:
      ConnectException - if the peer refuses the connection
      NoRouteToHostException - if the peer is not found or not reachable
      InterruptedIOException - if the connection timeouts
      I2PException - if there is some other I2P-related problem
    • run

      public void run()
      Non-final since 0.9.11. open will be true before being called. Any overrides must set listenerReady = true and then notifyAll() if setup is successful, and must call close() and then notifyAll() on failure or termination.
      Specified by:
      run in interface Runnable
    • manageConnection

      protected void manageConnection(Socket s)
      Manage the connection just opened on the specified socket
      Parameters:
      s - Socket to take care of
    • close

      public boolean close(boolean forced)
      Note that the tunnel can be reopened after this by calling startRunning(). This may not release all resources. In particular, the I2PSocketManager remains and it may have timer threads that continue running. To release all resources permanently, call destroy(). Does nothing if open is already false. Sets open = false but does not notifyAll().
      Specified by:
      close in class I2PTunnelTask
      Returns:
      success
    • destroy

      public boolean destroy()
      Note that the tunnel cannot be reopened after this by calling startRunning(), as it will destroy the underlying socket manager. This releases all resources if not a shared client. For shared client, the router will kill all the remaining streaming timers at shutdown.
      Overrides:
      destroy in class I2PTunnelTask
      Returns:
      success
      Since:
      0.9.17
    • closeSocket

      public static void closeSocket(Socket s)
    • clientConnectionRun

      protected abstract void clientConnectionRun(Socket s)
      Manage a connection in a separate thread. This only works if you do not override manageConnection(). This is run in a thread from an unlimited-size thread pool, so it may block or run indefinitely.
