Detailed Description

Interface class between database INTEGER types and type safe object identifiers OSB_LIB::Id<T>.

OtlId extends otl_value<long> with a conversion from an OSB object identifier, which converts an unset id to a NULL value. This makes it easy to use a nullable id in a database transaction.

Definition at line 169 of file otl.h.

Public Member Functions

• template<typename T> OtlId (const OSB_LIB::Id< T > &rhs)

  Conversion from type safe OSB object identifiers. The 'not set' identifier value is mapped to NULL.
  

• long id () const

  For use in the constructor of an OSB object identifier. A NULL value is translated to OSB_LIB::ID_NOT_SET.
  

Constructors to retain otl_value<T> functionality.

• OtlId ()

  Default constructor.
  

• OtlId (const otl_null &rhs)

  Conversion from otl_null.
  

Static Public Member Functions

• static long nvl ()

  The value for id() for a NULL value in the database.
