Class: McDbXrecord ​

2d.McDbXrecord

扩展记录类型，实体可以设置它的扩展记录，用于存放更多的信息。

Example

//写扩展记录
import { MxCpp, McDbDictionary, McDbXrecord, MxCADResbuf } from "mxcad"

let mxcad = MxCpp.getCurrentMxCAD();
let dict = mxcad.getDatabase().getNamedObjectsDictionary();

let sName = "MyDict";
let idDict = dict.getAt(sName);
if (idDict.isNull()) {
   let newDict = new McDbDictionary;
   idDict = dict.addObject(sName, newDict);
}
let myDict = idDict.getMcDbDictionary();
if (myDict) {
   let xrec = new McDbXrecord();
   let data = new MxCADResbuf();
   data.AddString("TestData");
   xrec.setData(data);
   myDict.addObject("MyRecord", xrec);
   console.log("write xrecord ok");
}

// 读取扩展数据。
async function MxTest_ReadxData() {
  let selEntity = new MxCADUiPrEntity();
  selEntity.setMessage("选择对象");
  let id = await selEntity.go();
  if (!id.isValid()) return;

  let ent = id.getMcDbEntity();
  if (ent === null) return;

  let data = ent.getxData();
  data.forEach((val, type, dxf) => {
    console.log(JSON.stringify({ val: val, type: type, dxf: dxf }));
  })
  
  //let data = ent.getxDataString("DataName");
  //MxFun.acutPrintf(data.val + "\n");
}
