// Description:
|
|
// 类 CKTObjSmartPtr 是AcDbObject派生的类的智能指针类，使用它可以管理类对象的
|
|
// 打开、创建、关闭、删除、比较等操作。
|
|
// 使用时，对于常用类由于做了宏定义只需在类名后跟上Ptr作为新类名声明对象使用
|
|
// 对于新类则按照模板类声明方式声明对象使用
|
|
// 如：AcDbLinePtr pLine; // 常用类时只需AcDbLine+Ptr作为类名声明对象
|
|
// CKTObjSmartPtr<CMyCustomObject> pMyObject; // 新类声明对象
|
|
// KT_OBJ_SMARTPTR_TYPEDEF(CMyObject); // 在派生类CMyObject的.h末尾加
|
|
// 其他地方就可直接使用
