[odb-users] Mapping abstract

[Bright Dadson]

I have a file called `Account.h` as shown below:

    #ifndef ACCOUNT_H_
    #define ACCOUNT_H_

   //forward declaration of address
   class Address address;
    
    #pragma db object abstract
    class Account
    {
      //fields and methods
      //Inverse bi-directional mapping to Address 
    };
    #endif /* ACCOUNT_H_ */

I also have a second file called `Address.h` as shown below:

    #ifndef ADDRESS_H_
    #define ADDRESS_H_
    #include "Account.h"
    
    typedef Account account_type;//Error her
    class Address
    {
     //Fields and methods
    };
    #endif /* ADDRESS_H_ */

My problem is, when I try to map to Account, I get the error `Account is Abstract`. I want to be able to map to the abstract instead of mappping to each base class - I think doing it this way will remove the verbosity of the mapping code across inherited classes.

Is there a simple way of doing this, can I map to the abstract base class, so all children classes will inherit this? Also Is my forward declaration of Address in Account correct? well considering they are different files.

Thanks.
