Method Detail

decode

Packet decode(ByteBuffer buffer,
              int limit,
              int position,
              int readableLength,
              ChannelContext context)
       throws TioDecodeException

根据ByteBuffer解码成业务需要的Packet对象. 如果收到的数据不全，导致解码失败，请返回null，在下次消息来时框架层会自动续上前面的收到的数据

Parameters:

buffer - 参与本次希望解码的ByteBuffer

limit - ByteBuffer的limit

position - ByteBuffer的position，不一定是0哦

readableLength - ByteBuffer参与本次解码的有效数据（= limit - position）

context - ChannelContext

Returns:

Packet

Throws:

TioDecodeException - TioDecodeException

encode

ByteBuffer encode(Packet packet,
                  TioConfig tioConfig,
                  ChannelContext context)

Parameters:

packet - Packet

tioConfig - TioConfig

context - ChannelContext

Returns:

ByteBuffer

handler

void handler(Packet packet,
             ChannelContext context)
      throws Exception

处理消息包

Parameters:

packet - Packet

context - ChannelContext
