Application :: systemDictionary - Get dictionary handle for system dictionary
The system dictionary is a built-in dictionary, which will be created for each ODABA application. The system dictionary provides type definitions for all system object types (complex data types and enumerations). This includes following groups:
- object type definitions (SDB)
- causality definitions (CAU)
- functional model definitions (ODC)
- documentation objects (DSC)
- administration object types (ADM)
- standard types ( DATE , LOGICAL , ...)
- internal types (interface classes)
Moreover, the system dictionary provides extent definitions for system extents. In order to obtain object type or extent definitions from the system dictionary, Dictionary ::typeDefinition() or Dictionary ::extentDefinition() might be called.
Return value: Dictionary handle ( odaba::Dictionary & )
The dictionary handle usually refers to an opened dictionary. Calling functions with invalid dictionary handles may cause an exception. For checking the dictionary handle, isValid() can be called.
