This template class is defined in MapColl.h.
template <class ApiObj> class AcMapObjArray
The AcMapObjArray class is used for dynamic object arrays. It stores ApiObj objects in the member data.
To use this template for collecting objects of a particular class, you must define the operator= function for the class.
The AutoCAD Map ARX API uses AcMapObjArray and AcMapObjPtrArray instead of MFC collections to provide array services.
A dynamic object array can grow as needed at runtime.
