Detailed Description
A reference to a SomeData.
This class is useful for having clones of objects.
The matrix in SomeDataRef is meant to overwrite the matrix of thedata. This is unlike a group with 1 object in that with groups, the matrices are multiplied.
Constructor & Destructor Documentation
| LaxInterfaces::SomeDataRef::SomeDataRef | ( | SomeData * | d | ) |
Increments count of d.
References LaxInterfaces::SomeData::Id(), Laxkit::anObject::inc_count(), and newstr().
|
virtual |
Decrement count of thedata, if any.
Member Function Documentation
|
virtual |
Only read in the id. It is up to the program reading in to substitute references for actual objects.
Reimplemented from LaxInterfaces::SomeData.
References Laxkit::PtrStack< T >::e, makestr(), and Laxkit::PtrStack< T >::n.
|
virtual |
Return an actual object at the end, if we are pointing to another clone. If final object is an empty ref, then return NULL.
