Class UDPPacketReader

    java.lang.Object
      net.i2p.router.transport.udp.UDPPacketReader

     class UDPPacketReader

extends Object

To read a packet, initialize this reader with the data and fetch out the appropriate fields. If the interesting bits are in message specific elements, grab the appropriate subreader.
