1 构造函数
创建一个未连接的 IPv4 数据报 Socket：
DatagramSocket();创建一个指定 IP 类型（IPv4 或 IPv6）的数据报 Socket：
explicit DatagramSocket(IPAddress::Family family);创建一个指定 SocketAddress 的数据报 Socket
DatagramSocket(const SocketAddress& address, bool reuseAddress = false);DatagramSocket(const Socket& socket); ???/// Creates the DatagramSocket with the SocketImpl ???/// from another socket. The SocketImpl must be ???/// a DatagramSocketImpl, otherwise an InvalidArgumentException ???/// will be thrown.2 重载运算符
DatagramSocket& operator = (const Socket& socket); ???/// Assignment operator. ???/// ???/// Releases the socket‘s SocketImpl and ???/// attaches the SocketImpl from the other socket and ???/// increments the reference count of the SocketImpl. ??3 常用操作
3.1 连接与绑定
void connect(const SocketAddress& address);void bind(const SocketAddress& address, bool reuseAddress = false);3.2 收发数据且不考虑 client
int sendBytes(const void* buffer, int length, int flags = 0);int receiveBytes(void* buffer, int length, int flags = 0);3.3 手法数据且获取 client 的 SocketAddress
int sendTo(const void* buffer, int length, const SocketAddress& address, int flags = 0);int receiveFrom(void* buffer, int length, SocketAddress& address, int flags = 0);3.4 收发广播
void setBroadcast(bool flag);bool getBroadcast() const;4 protected 函数
DatagramSocket(SocketImpl* pImpl);-
