* TCPAccept与SocketManage
|

*
|

|
|
* TCPAccept: 客户端连接到服务器后的控制对象

* SocketManage: 服务器对批量TCPAccept进行管理的对象
|

|
|
* SocketManageThread: SocketManage的异步封装
|
|||
|
|
*
|
|||
|
|
* 收包流程:
|
|||
|
|
* 1.SocketManage通过OnSocketRecv函数通知TCPAccept接收数据
|
|||
|
|
* 2.TCPAccept在收满4个字节的包长后，根据包长向MultiLevelMemoryPool申请缓冲区
|
|||
|
|
* 3.TCPAccept收满一个包后，通过OnRecvPacket事件函数通知开发者有包了
|
|||
|
|
* 4.TCPAccept将缓冲区送回BufferPool
