Description
The AcBrEntity class is the interface base class for topology objects. This class defines the functions that are common to all topology objects, and cannot be instantiated as it has no meaning on its own. It is derived from AcRxObject to provide full-service, runtime type checking for all derived topology classes.
Remarks
The AcBrEntity class casts aggregate collections of derived class objects for purposes of storing and retrieving from an array (such as AcDbVoidPtrArray) and declares pointers to topology objects whose subentity type will not be known until after a function call.
