Usage

From source file:ru.jts_dev.authserver.packets.LoginClientPacketHandler.java

public final IncomingMessageWrapper handle(final ByteBuf buf,
        @Header(CONNECTION_ID) final String connectionId) {
    if (buf.readableBytes() == 0)
        throw new RuntimeException("At least 1 readable byte excepted in buffer");

    final int opcode = buf.readByte();
    final IncomingMessageWrapper msg;
    switch (opcode) {
    case 0x00:/* w w w  .  ja v  a  2 s  .c  o m*/
        msg = context.getBean(RequestAuthLogin.class);
        break;
    case 0x02:
        msg = context.getBean(RequestServerLogin.class);
        break;
    case 0x05:
        msg = context.getBean(RequestServerList.class);
        break;
    case 0x07:
        msg = context.getBean(AuthGameGuard.class);
        break;
    default:
        throw new RuntimeException("Invalid packet opcode: " + Integer.toHexString(opcode));
    }

    final ByteBuf data = buf.slice();

    Class<? extends IncomingMessageWrapper> packetClass = msg.getClass();
    log.trace("received packet: {}, length: {}", packetClass.getSimpleName(), data.readableBytes());

    final MessageHeaders headers = msg.getHeaders();
    headers.put(CONNECTION_ID, connectionId);
    msg.setPayload(data);

    return msg;
