DBFieldDef :: GetStaticFieldDef - Get static field definition for basic data type

Implementation overview

• Get static field definition by type number
  DBFieldDef :: GetStaticFieldDef ( ityp )
• - internal feature (not documented)
  DBFieldDef :: GetStaticFieldDef ( ityp, size )
• Get static field definition for meta-type by name
  DBFieldDef :: GetStaticFieldDef ( prop_names )
• Get static field definition for meta-type
  DBFieldDef :: GetStaticFieldDef ( meta_type )

Implementation details

1. Get static field definition by type number
   DBFieldDef * DBFieldDef  :: GetStaticFieldDef ( int16 ityp )
   

   • ityp - Internal data type number

     For user-defined data types (complex data types or enumerations) the internal type identification is a unique number within a schema (dictionary). For ODABA built-in data types the value is negative.

2. - internal feature (not documented)
   DBFieldDef * DBFieldDef  :: GetStaticFieldDef ( int16 ityp, uint32 size )
   

   • ityp - Internal data type number

     For user-defined data types (complex data types or enumerations) the internal type identification is a unique number within a schema (dictionary). For ODABA built-in data types the value is negative.

   • size - Size

     Size of the instance or string area.

3. Get static field definition for meta-type by name
   DBFieldDef * DBFieldDef  :: GetStaticFieldDef ( NString &prop_names )
   

   • prop_names - Property name

     The property name is passed as 0-terminated string. It may contain a property path that consists of a sequence of property names.

4. Get static field definition for meta-type
   DBFieldDef * DBFieldDef  :: GetStaticFieldDef ( MAT_Types meta_type )
   

   • meta_type - - internal feature (not documented)
