Beetle.NetPackage是一个多平台Client Socket TCP通讯组件（Apache License 2.0），组件制统一的对象协议制定规则，可以灵活方便地通过对象来描述TCP通讯交互。现有支持平台有Flash,.NET和Android。组件为了统一编写规范制定了不同语言平台下访问TCP服务的统一处理规则;分别有协议描述规范和消息处理控制。不同语言平台下都提供了一致的对象和接口主要包括：IMessage,Packge,INetClientHandler和NetClient等。
IMessage
消息描述接口，所有通讯消息必须实现相关规则。
flash
public class Register implements IMessage { public var Name:String; public var EMail:String; public var City:String; public var Country:String; public var RegTime:Date; public function Register() { } public function Load(reader:ByteArray):void { Name= reader.readUTF(); EMail= reader.readUTF(); City= reader.readUTF(); Country = reader.readUTF(); var dv:String= reader.readUTF(); RegTime=DateFormatter.parseDateString(dv); } public function Save(writer:ByteArray):void { writer.writeUTF(Name); writer.writeUTF(EMail); writer.writeUTF(City); writer.writeUTF(Country); var d:DateFormatter =new DateFormatter(); d.formatString="YYYY-MM-DD HH:NN:SS"; writer.writeUTF(d.format(RegTime)); } } android
public class Register implements IMessage { public String Name; public String EMail; public String City; public String Country; public Date RegTime; @Override public void Load(DataInputStream stream) throws Exception { // TODO Auto-generated method stub Name = stream.readUTF(); EMail = stream.readUTF(); City = stream.readUTF(); Country = stream.readUTF(); String format = "yyyy-MM-dd HH:mm:ss"; SimpleDateFormat sdf = new SimpleDateFormat(format); RegTime = sdf.parse(stream.readUTF()); } @Override public void Save(DataOutputStream stream) throws Exception { // TODO Auto-generated method stub stream.writeUTF(Name); stream.writeUTF(EMail); stream.writeUTF(City); stream.writeUTF(Country); String format = "yyyy-MM-dd HH:mm:ss"; SimpleDateFormat sdf = new SimpleDateFormat(format); stream.writeUTF(sdf.format(RegTime)); }} c#
public class Register:Beetle.NetPackage.IMessage { public String Name; public String EMail; public String City; public String Country; public DateTime RegTime; public void Load(Beetle.NetPackage.BufferStream reader) { Name = reader.ReadUTF(); EMail = reader.ReadUTF(); City = reader.ReadUTF(); Country = reader.ReadUTF(); string date = reader.ReadUTF(); Console.WriteLine(date); RegTime = DateTime.ParseExact(date, "yyyy-MM-dd HH:mm:ss", CultureInfo.InvariantCulture); } public void Save(Beetle.NetPackage.BufferStream writer) { writer.WriteUTF(Name); writer.WriteUTF(EMail); writer.WriteUTF(City); writer.WriteUTF(Country); writer.WriteUTF(RegTime.ToString("yyyy-MM-dd HH:mm:ss")); } } Package
该对象是用于通讯协议描述，默认实现４字节描述消息大小规范。Package的主要工作是对象写入通讯数据和从通讯数据获取对象。对象只是提供一个基础的处理规则，在应用中使用者必须从此类的基础上派生出新的协议处理对象。
flash
public class NPPackage extends Package { public function NPPackage() { super(); } protected override function WriteMessageType(writer:ByteArray, message:IMessage):void { writer.writeUTF(flash.utils.getQualifiedClassName(message)); } protected override function GetMessage(reader:ByteArray):IMessage { var name:String = reader.readUTF(); if(name=="Register") return new Register(); return null; } } android
public class NPPackage extends Package { @Override protected void WriteMessageType(DataOutputStream writer, IMessage message) throws Exception { // TODO Auto-generated method stub writer.writeUTF(message.getClass().getSimpleName()); } @Override protected IMessage GetMessage(DataInputStream reader) throws Exception { // TODO Auto-generated method stub String name= reader.readUTF(); if(name.equals("Register")) return new Register(); return null; }} c#
class NPPackage:Beetle.NetPackage.Package { protected override void WriteMessageType(Beetle.NetPackage.BufferStream writer, Beetle.NetPackage.IMessage message) { writer.WriteUTF(message.GetType().Name); } protected override Beetle.NetPackage.IMessage GetMessage(Beetle.NetPackage.BufferStream reader) { string Name = reader.ReadUTF(); switch (Name) { case "Register": return new Register(); } return null; } } INetClientHandler
该接口主要用于描述TCP连接处理规则，包括有数据接收事件，错误处理事件，连接创建成功和失败事件。
public interface INetClientHandler { void Receive(NetClient client, Object msg); void Error(NetClient client, Exception e); void Disposed(NetClient client); void Connected(NetClient client);} NetClient
该对象主要用于创建ＴＣＰ通讯和进行消息发送接收处理。

mClient = new NetClient("127.0.0.1",9088,new NPPackage(),new NetClientHandler( ClientReceive,ClientError,ClientDisposed,ClientConnected));mClient.SocketEndian = Endian.BIG_ENDIAN;mClient.Connect(); android
mClient = new NetClient("10.0.2.2", 9088, new NPPackage(), this);mClient.Connect(); c#
mClient = new Beetle.NetPackage.NetClient("127.0.0.1", 9088, new NPPackage(), this);mClient.LittleEndian = false;mClient.Connect();
