通过 SuperObject 的公用函数 SO 实现一个 ISuperObject 接口非常方便;
前面都是给它一个字符串参数, 它的参数可以是任一类型甚至是常数数组.
SA 和 SO 都是返回一 ISuperObject;
SO 可以产生一个 stArray 类型的 ISuperObject, 但 SA 只会产生 stArray 类型的 ISuperObject;
SA 的参数也只能是常数数组.
unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TForm1 = class(TForm) Button1: TButton; Button2: TButton; procedure Button1Click(Sender: TObject); procedure Button2Click(Sender: TObject); end; var Form1: TForm1; implementation {$R *.dfm} uses SuperObject, TypInfo; procedure TForm1.Button1Click(Sender: TObject); var jo: ISuperObject; begin jo := SO([‘A‘,1, ‘B‘,2.5, ‘C‘,‘xyz‘, ‘D‘,True]); ShowMessage(jo.AsJSon); // {"D":true,"C":"xyz","B":2.5,"A":1} {显示类型名} ShowMessage(GetEnumName(TypeInfo(TSuperType), Ord(jo.DataType))); // stObject jo := SO(3.14); ShowMessage(jo.AsJSon); // 3.14 {显示类型名} ShowMessage(GetEnumName(TypeInfo(TSuperType), Ord(jo.DataType))); // stDouble jo := SA([‘A‘,1, ‘B‘,2.5, ‘C‘,‘xyz‘, ‘D‘,True]); ShowMessage(jo.AsJSon); {显示类型名} ShowMessage(GetEnumName(TypeInfo(TSuperType), Ord(jo.DataType))); // stArray end; //SA 再举例 procedure TForm1.Button2Click(Sender: TObject); var jo,ja: ISuperObject; begin ja := SA([‘x‘,‘y‘,‘z‘]); jo := SO(‘{A:1, B:2}‘); jo[‘B‘] := ja; ShowMessage(jo.AsJSon); // {"B":["x","y","z"],"A":1} end; end.
