数据管理器CdataManager

平台管理器——CPlatManager平台绘图接口：CdataIO_draw平台实体变更：增加图块、移动等获取、设置数据包的信息：获得当前数据包CvectorPackageData*Nonce_GetData();设置当前数据包CvectorPackageData*Nonce_SetData(CvectorPackageData*pData);获得数据包intGetDataNo(CvectorPackageData*pData);intaddCurrPackage(BOOLcheckFlag=TRUE,BOOLsetCurrFlag=TRUE); //增加当前包数据管理器——CdataManager

对数据包里面的数据进行处理：voidpackage_CopyAll(CvectorPackageData*pData0,CvectorPackageData*pData1,intisSelect);对层进行操作：intLayerNameGetLayerNo(intpackageNo,CStringlayerName); //由层名取层号对实体的操作：doubleentity_CalcEllipseAcreage(intpackageNo,intentityNo); //计算一个实体椭球面积对标准属性的操作：CStringentity_GetAttribValueByName(intpackageNo,intentityNo,CStringfldName);

//获得一个标准属性值,通过字段名称数据包——CvectorPackageData*数据管理器对象指针：
