All Known Implementing Classes:
ByteBufPacketReader
public interface PacketReader
Interface for decoding packets into data.

used to abstract out the implementation details of netty.

  • Method Details

    • readString

      String readString(int length)
      Reads the next N bytes as a string.

      NOTE:Strings in KRO are 0-terminated and use pre-determined lengths. So "hello" of length 20 will be "hello" 0x0 0x0 0x0...

      Parameters:
      length - the size of the string, with zero padding.
      Returns:
      The string object.

    • readBytes

      byte[] readBytes(int length)

    • readInetAddressAndPort

      InetAddressAndPort readInetAddressAndPort() throws UnknownHostException
      Reads the address and port pair from the kro server byte stream, which is a 6-byte series.
      Returns:
      The IP address and port pair
      Throws:
      UnknownHostException

    • readShortLE

      short readShortLE()
      Returns:
      the next 4-byte short in the stream

    • readIntLE

      int readIntLE()
