INTERFACE - components

The following declaration statements are possible for components:

• TYPE-POOLS, TYPES, DATA, CLASS-DATA, CONSTANTS for data types and data objects

• METHODS, CLASS-METHODS, EVENTS, CLASS-EVENTS for methods and events

• INTERFACES for the inclusion of component interfaces, and ALIASES for alias names for components of interfaces

The only interface components that can be addressed without implementation of the interface in classes are data types and constants. The latter can be addressed using the name of the interface and the class component selector (=>).

Note

All components of an interfaces are in one namespace. Within an interface, the name of a component must be unique, regardless of its type (data type, attribute, method, event , or alias name). The components of an included interface are identified by the prefix intf~ (name of the interface with interface component selector).
