示例1: on_readable
//要求fd是非阻塞的
HANDLE_RESULT NetInterface::on_readable(int fd)
{
SLOG_TRACE("socket on_readable. fd=%d", fd);
TransSocket* trans_socket = (TransSocket*)m_socket_manager->find_trans_socket(fd);

{
SLOG_ERROR("can't find trans socket in socket manager. fd=%d", fd);

}
ByteBuffer *raw_data_buffer = NULL;
unsigned int header_length = 0;
ProtocolHeader *header = m_protocol_family->create_protocol_header();
assert(header != NULL);
header_length = header->get_header_length();
assert(header_length > 0);
//1. 检查是否有未处理数据
raw_data_buffer = trans_socket->pop_recv_buffer();
if(raw_data_buffer == NULL) //新的协议包
raw_data_buffer = new ByteBuffer();
unsigned int raw_data_size = raw_data_buffer->size();
if(raw_data_size < header_length) //读协议头数据
{

}

//2. 解码协议头

//3. 接收协议体数据
if(body_length > 0) //允许空协议体

//4. 解码协议体
Protocol *protocol = m_protocol_family->create_protocol_by_header(header);
