Member Function Documentation

§ Clone()

void CDataCellItem::Clone ( IObject obj) const
virtual

Clone the object's contains to a pointer.

The caller should allocate the memory and pass the pointer to this function.. Inheritance should implement this function void Clone(IObject*) and IObject* Clone() should have the same behavior In some cases, if you want to avoid Dead Reference( one object is being referred to by many objects and you can't update all the references). It is possible to use this function to replace the contains at a given pointer. But this may result in memory leak if you do not implement this function carefully or misuse it.

Reimplemented from ParaEngine::IObject.

§ operator=()

CDataCellItem & CDataCellItem::operator= ( const string &  value)
virtual

Assigning different value to the cell.

If type not match, nothing will happen;
