Detailed Description

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

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

Member Function Documentation

template<typename T, int ST>

OSB_LIB::TypeId<T, ST> OSB_DB::OtlType::mkType

(

OSB_LIB::TypeId< T, ST > &

dest

)

const [inline]

For use in the constructor of an OSB type identifier.

A NULL value is translated to OSB_LIB::Type<T>().

Parameters:

dest

Type identifier to populate, see below.

Returns:

Reference to dest.

Note:

The argument allows for implicit template instantiation:

          OtlType origin;
          OtlType dest;
          // fetch into origin ...
          OSB_LIB::CpMapper::Type t;
          OSB_LIB::UsageMapping mapDef(ut,
                                       origin.mkType(t),
                                       dest.mkType(t));
