CLASS - components

The components of the classes are defined in the visibility sections. The following declaration statements are possible for components:

  • INTERFACES for implementing interfaces and ALIASES for alias names for interface components

Other versions: 7.31 | 7.40 | 7.54


All the components in a class are in one namespace. The name of a component must be unique to its type (data type, attribute, method, event, or alias name) within one class. The components of an implemented interface are marked with the prefix intf~ (name of the interface with interface component selector).
