//      returning from AddToDb() to change the wrapper state and establish
//      database reactors for the database resident object.

//      Override this method to create a non-database resident
//      wrapped object of the correct type. Be sure to attach it to the
//      encapsulated AcAxObjectRef before returning.
//
// Derived classes should also call Fire_Notification before returning from any
// method which modifies a non-database resident object. This call is necessary
// because the notification mechanism used by the default implementation relies
// on AcDbObjectReactors and does not work for non-database resident objects.

// Derived classes wanting to support non-database resident objects should
// override the following methods:
//
//      1. ForceDbResident
//      Override this method to return VARIANT_FALSE.
//
//      2. AddToDb
//      Override this method to add a non-database resident wrapped
//      object to a database. Be sure to call SetObjectId on the wrapper before
//      returning from AddToDb() to change the wrapper state and establish
//      database reactors for the database resident object.
//
//      3. CreateObject
//      Override this method to create a non-database resident
//      wrapped object of the correct type. Be sure to attach it to the
//      encapsulated AcAxObjectRef before returning.
//
// Derived classes should also call Fire_Notification before returning from any
// method which modifies a non-database resident object. This call is necessary
// because the notification mechanism used by the default implementation relies
// on AcDbObjectReactors and does not work for non-database resident objects.
