Definicja interface type

Collection of attribute, method, and event definitions, used in a common context.

An object type can support one or more interface types. The attributes, methods, and events already defined in the interface types are therefore available to the object type with their interfaces, and are also passed on to the relevant subtypes. If interface types are used, names and interfaces are standardized, and the definition of attributes, methods, and events in the object type definition is simplified.
