优秀的数据序列和还原类----TSimpleMsgPack

TSimpleMsgPack是D10天地弦的作品。

优点：至简，就一个单元文件实现，不需要引用其他单元。

缺点：不是标准的MSGPACK实现，不能跨语言兼容。

所以：TSimpleMsgPack只能用于DELPHI开发，不能用于其他语言。

而QDAC的QMsgPack却是标准的MSGPACK实现，能跨语言兼容。

有了它，从此数据的序列和还原不再是梦魔。

适用极广：可以适用于所有版本的DELPHI，不论D7还是最新的XE10.1，都支持。激动！

封装极简：完全独立的一个单元即可，不需引用任何其它的单元。

用法极简：调用非常简单。

其支持的序列的数据格式非常丰富。

下面列出该类的一些常用的接口方法：

procedure LoadBinaryFromStream(pvStream: TStream; pvLen: cardinal = 0);
procedure SaveBinaryToStream(pvStream:TStream);

procedure LoadBinaryFromFile(pvFileName:String);
procedure SaveBinaryToFile(pvFileName:String);

procedure EncodeToStream(pvStream:TStream);
procedure EncodeToFile(pvFileName:string);

procedure DecodeFromStream(pvStream:TStream);
procedure DecodeFromFile(pvFileName:string);

function EncodeToBytes: TBytes;
procedure DecodeFromBytes(pvBytes:TBytes);

function Add(pvNameKey, pvValue: string): TSimpleMsgPack; overload;
function Add(pvNameKey: string; pvValue: Int64): TSimpleMsgPack; overload;
function Add(pvNameKey: string; pvValue: TBytes): TSimpleMsgPack; overload;
function Add(pvNameKey: String): TSimpleMsgPack; overload;

function ForcePathObject(pvPath:string): TSimpleMsgPack;

/// <summary>
/// remove and free object
/// false : object is not found!
/// </summary>
function DeleteObject(pvPath:String):Boolean;
