return es; } 请问我这个自定义实体类保存读取出错在哪儿？

还有本例中夹点函数、拉伸函数、变换函数以及对象捕捉点函数如何编程？ Acad::ErrorStatus cascoCEntity::getGripPoints(AcGePoint3dArray& gripPoints, AcDbIntArray& osnapModes, AcDbIntArray& geomIds) const {。。。。}

Acad::ErrorStatus cascoCEntity::getStretchPoints(AcGePoint3dArray& stretchPoints) const {。。。。}

Acad::ErrorStatus cascoCEntity::moveGripPointsAt(const AcDbIntArray& indices, const AcGeVector3d& offset) {。。。。}

Acad::ErrorStatus cascoCEntity::moveStretchPointsAt(const AcDbIntArray& indices, const AcGeVector3d& offset) {。。。。}

请各位大侠帮帮忙呀，能不能给出一个从实体类派生的例子。谢谢大家。
