This wraps the ObjectARX AcDbAssocPersSubentIdPE class. 

This is a AcRx protocol extension base class that defines protocol to obtain a persistent query and manipulation protocol that is not available in the Entity class proper so that the client code can manipulate subentities of entities. 

The derived concrete classes implement this protocol for the individual derived Entity classes. Only the methods that are pertinent to the particular Entity type need to be overridden. 

Notice that ObjectARX provides an implementation of the AssocPersSubentityIdPE protocol extension for the common entity types such as Line, Circle, Arc, Polyline, Polyline2d, etc.
