    • setRestartPending

      public void setRestartPending()
      The router told us it's going to restart. Call instead of setActive(false).
      Since:
      0.9.34

    • setActive

      public void setActive​(boolean active)

    • getActive

      public boolean getActive()

    • receiveNewSyn

      public void receiveNewSyn​(Packet packet)
      Non-SYN packets with a zero SendStreamID may also be queued here so that they don't get thrown away while the SYN packet before it is queued. Additional overload protection may be required here... We don't have a 3-way handshake, so the SYN fully opens a connection. Does that make us more or less vulnerable to SYN flooding?

    • accept

      public Connection accept​(long timeoutMs) throws RouterRestartException, ConnectException, SocketTimeoutException
      Receive an incoming connection (built from a received SYN) Non-SYN packets with a zero SendStreamID may also be queued here so that they don't get thrown away while the SYN packet before it is queued.
      Parameters:
      timeoutMs - max amount of time to wait for a connection (if less than 1ms, wait indefinitely)
      Returns:
      connection received. Prior to 0.9.17, or null if there was a timeout or the handler was shut down. As of 0.9.17, never null.
      Throws:
      RouterRestartException - (extends I2PException) if the router is apparently restarting, since 0.9.34
      ConnectException - since 0.9.17, returned null before; if the I2PServerSocket is closed, or if interrupted.
      SocketTimeoutException - since 0.9.17, returned null before; if a timeout was previously set with setSoTimeout and the timeout has been reached.
